How To fix a Virus Infected Computer

These days malicious software is becoming an epidemic. It seems like it’s everywhere. Also, there’s been a change in the way Malware / Virus  acts. It used to be that it would slow down your computer, or display annoying popups, but now malware is becoming increasingly discreet. You could be infected right now ,and not even know it. Also, it often seems as if the only way to make sure you’re not infected is to scan your computer with numerous anti-malware programs. Doing this can be time  consuming and, while scanning, may even slow your computer to a crawl. Even after that you still can’t be sure you’re clean. This is because scanners cannot recognize all new malware.

2. How To fix a Virus Infected Computer

 Because of these difficulties I have come up with a better method. This uses multiple programs, not to remove files, but just to analyze the computer. Each of these programs is very effective and easy to use. They are all portable applications and will not cause any conflicts on your computer because they are only running when you’re using them. However, they do require an active internet connection to function properly. Don’t worry, these steps will also help you to fix your internet connection in the event that it is not working. After you have already gone through the below process once, and had all files whitelisted, this approach is much faster, much more certain, and much easier than any other approach I’ve seen. No active malware  / virus can escape this process. However, inactive pieces of malware may not be flagged by this approach but may be found by other scanners. Rest assured that these are not direct threats to the safety of your computer and thus do not constitute a failure of this article. These are some of the scanners I run while a repairing an infected computer.

1.  Malwarebytes Premium

2.  Hitman Pro

3. ComboFix

Even after a Virus infected computer has been removed from a system many of the problems caused by it may still remain. That said, one of the first things you should do in order to fix any of these problems is to make sure that all infections have actually been removed. Read my article  to find out What Is Malware. If you know that you still have infections on your computer then, instead of trying to fix problems while the virus  infection still present, you should first remove all virus/malware infections. To do this please see my article about How to Repair your Computer before seeking IT Support.

3. How To fix a Virus Infected Computer

Once you have confirmed that your computer is entirely free of malware you should then back up all of your important files. This way if anything goes wrong while fixing the computer, which is a very real possibility, your important documents will still be intact. There’s one more thing that I always do after a virus / malware removal  and it’s to make sure you tune up your computer, One of the best free software’s out there is Ccleaner it’s very safe to use, just make sure you always backup your registry via Ccleaner software.  or see another option, my article on How To Tune Up Your System

Finally,  Stop thinking that a free antivirus will safe you in today’s Virus World,  that will never happened.  If you want to be safe from Trojans, spend the money on a a real antivirus I recommend  Malwarebytes Premium .

20 Troubleshooting Steps To Diagnose and Repair your Mac OS X System

Macbook Repair Miami

Steps to Diagnose and Repair your Mac OS X System.

1. Restart

Restart  your system, Many of the times this very simple process resolve many of your issues.

2. Check/fix the file system

There are many different ways to do this. You can boot off the OS X Installation CD, run Disk Utility, and select Repair Disk. If you don’t have access to the CD, you can also run the UNIX           command fsck from the Terminal in Single User Mode. The specific sequence of how to do this varies depending on what version of OS X you’re running. Go to Apple Support for specific instuctions.
Disk Utility will report back whether or not there were any problems, and whether or not it could fix any problems. If it is unable to fix a problem, then you need to get a 3rd party utility, or reformat the disk before doing any other troubleshooting. NOTE: reformatting the disk will erase it, so a 3rd party utility is usually a better idea.

You can also use a 3rd party utility like DiskWarrior or Norton Disk Doctor These 3rd party utilities can fix some kinds of errors that the free Apple tools cannot. (But don’t ever install the Norton components on your hard drive – just run the tools by booting off the Norton CD.)

If there were errors that needed to be fixed, and your software reports that they were all successfully fixed, you may have solved your larger problem.

3. Make sure you’re not running out of free space on the System volume

When the system is running out of memory, it needs to write swap files to your hard drive. If your hard drive is already almost full, then the system will bog down into unusability. Keep tabs on how much free space you have on your boot disk by getting info on that disk in the Finder. Alternatively, you can use the excellent freeware DiskSpace application, which will give you a display of free space on your menubar.
You should have at *least* 500MB to 1GB of free space at all times. Realistically you would want more than that, especially if you plan on burning CD/DVD’s. Remember that even if you have more free space than this when you first booted, swapfiles can eat up diskspace quickly – 2GB or more of swapfiles is not unheard of. So it’s a good idea to have at least 3GB of free space immediately after booting.

To fix: trash unneeded files and applications off of your System volume to free space. And try to create fewer swap files by adding more RAM or running fewer applications simultaneously. Restarting will temporarily get rid of all swap files, but they’ll come back.

4. Repair permissions

Run this in Disk Utility in your normal login. Open Disk Utility in the Applications/Utilities folder. Select the boot drive ( probably “Macintosh HD” ), click on the First Aid tab and click the Repair Permissions button. See if this cures the problem.

5.  Create a new user account. 

You do this by creating a new user in the Accounts tab of System Preferences, logging out of your main account, and logging into the new account. If this makes the problem go away, it means the cause is in your user account.

While it’s good that we know approximately where the problem is, unfortunately there’s a lot of stuff in the user account to pick through. And now you will have to do some serious troubleshooting. Oftentimes, this will be a preferences file in ~/Library/Preferences/. If you can pinpoint that one bad file, you’re done. If you have no idea what’s going on you can try the laborious process of keeping that new account you made, and bringing over the files one by one until you find the one that was the problem. Even easier is to ask an expert if it’s a frequently seen problem, first letting them know that it was a problem in your user account.

6. Clear system & user caches

Use a third party tool like Cocktail or Disk Warrior / Panther Cache Cleaner  to deep clean all caches. Reboot. See if this cures the problem.

7. Disable Application Enhancer, if you’re running it

Haxies from Unsanity. They’re great, and they’re pretty well programmed, but they’re hacking the system in non-standard ways. Unsanity claims that APE will be disabled by holding down the shift key while logging in. However, if you want to be ultra-safe about it, download the APE installer from Unsanity and use the ‘uninstaller’ option to remove all traces.

8.  Startup in SafeBoot mode, and see if the problem continues

You do this by holding down the shift key during bootup. If this makes the problem disappear, then it is a problem with Extensions or StartupItems. And most likely, those would be 3rd party Extensions or StartupItems. Most of those are kept in /Library/Extensions/ and /Library/StartupItem/. Move those items to the desktop, and see if you can isolate which one was causing the trouble. There are also some 3rd party extensions that are *annoyingly* installed in /System/Library/Extension/, however you must be very very careful mucking around in there, as almost all of those Extensions are supplied by Apple, and your machine will not function without them. Use common sense, and ask the experts.

9.  Reset Firmware

Resetting your firmware will reset all firmware settings back to factory defaults. Things like the boot rom, power management, etc. are found in the firmware. To do this hold down the following buttons on your keyboard at boot up: cmd+opt+O+F. Once in open firmware type these commands:

reset-nvram (hit return)
reset-all (hit return once more, the system should reboot)

10. Unplug all USB, Firewire devices except Apple mouse

Reboot with everything unplugged. If this makes the problem go away, then you have a bad external device, bad cable, or bad port on your computer. Try to isolate which one it is. Be especially wary of USB hubs.

11. Reapply the latest combo updater

Download the latest OS X updater from Apple. These updaters come in 2 flavors, an updater which will only update the next most recent version of the OS, and a combo updater, which will update all versions since the last paid update. You want the combo updater. It will be labeled as the combo updater, and it will be much larger than the normal updaters – around 80MB at this time. Find the updater on Apply the updater, even if your system version number is already up to date. See if this cures the problem.

12. Run the Apple hardware diagnostic CD

Boot off the CD by restarting while holding down the C key on the keyboard. See if you get any useful information.

13.  Check the hard drive for bad blocks

One way of doing this is to try to re-initialize your drive using Drive Setup from the OS X Installation disk. Unfortunately, this will wipe out all of your data, so back up first, if that’s the route you go. If the initialization fails, your disk is worthless garbage and must be replaced.

You can use the TechTool Deluxe CD that came with the Apple Protection Plan to check for bad blocks. Norton Disk Doctor will also allow you to test for bad blocks without erasing your disk using the Check Media option. Other 3rd party disk utilities may allow this as well. Hearing odd noises coming from your drive is a tip-off that this may be your trouble.

14.  Take out 3rd party RAM

See if this cures the problem.

15.  Unplug 3rd Party PCI cards

If this solves the problem, replace the cards one by one until you identify the problematic card. Contact the manufacturer to see if updated drivers are available.

16.  Reset PMU

The PMU’s (Power Management Unit’s) location, and how to reset it, varies by machine. Go to Apple Support to find out how to do it for your particular machine. See if this cures the problem. Typically this will fix issues when your system will not power on.

Make sure you only hold in the PMU button for a second. DO NOT hold it in for any longer and DO NOT press it more than once. If you do this it could result in corrupting the PMU itself.

17.  Archive and Install OS X

This will archive user/network settings and replace your current system folder with a new one. Boot off your OS X cd and run through the install as normal. Once you get to the screen where you select which hard drive you want to put the OS on there should be an options button under the hard drive. Select it and then select the archive and reinstall button. Then proceed through the install as normal. This may or may not fix your problem, and it can save you time from copying back ups back over, resetting user preferences, and reinstalling applications.

18.  Reinstall the system from scratch

This step is annoying and time consuming, which is why we’ve saved it for second to last. It requires erasing your hard drive, so you’ll have to either back up, or lose, all of your data.

19.  Send the machine back to Apple

This step is very annoying, very time-consuming, and if the machine is out of warranty, can be very very expensive. So try a couple of the other steps first. Call Apple Support to arrange a pickup or locate an an Apple Authorized Service Provider.

20.  Additional Notes

Uninstall Antivirus Products if you’ve installed them

I have ran my Mac for the past 7 years  and still never seen a Virus until today.

Check your error logs
Check your system logs to see if there is anything relevant to your problem listed there. To do so simply go to the apple menu and select about this computer. A window will pop up displaying some basic information about your computer. Click on the more info button at the bottom of the window. This will bring up Apple System Profiler (ASP). The last tab furthest to the right of the ASP will be labled “Logsâ€? click on it and then select console. It should list error messages related to each application you are having problems with.

Start your system in verbose mode
Start up your computer in verbose mode, hold down cmd+V at start up. You will see the a bunch of text scroll down the screen as everything starts up. Look for anything that gives an error message and record it. Try doing Google searches, or search forums to see if the problem has already been discussed and a known fix has been established. A lot of times you can find fixes on these forums, they are a great tool.

ESD safety is important when working inside your computer
You do not want to damage any component when removing it. Refer to the manual that came with your computer, or Apple Support on the web.

How to Repair Windows 7 Boot problems

How to Repair Windows 7 Boot problems / Miami Lakes Computer Repair

 

This is one of the most common problems with Microsoft operating system.  I’ve decided to uncover some of the fixes I apply to get Windows back on the Desktop.

 

Check your BIOS settings 

Make sure to check the boot order in your Bios Settings. In many cases, having Windows 7 fail to boot may be as simple as having your BIOS set with an incorrect boot order sequence.  It can be quite common if you have more than one hard drive installed in your computer and your BIOS gets reset. Usually  you can access your BIOS seconds after your computer turns on by pressing the Delete button or by pressing a specific  function key. Once in the BIOS, check to see that your system drive is listed appropriately in the boot order sequence; you may need to refer to your motherboard manual for help;

Another possible reason is  to make sure all the cables are plugged in properly. If your hard drive is making an odd noise, such as a clicking sound, your hard drive may be broken. Finally, it is possible that the hard drive is having data corruption issues , which has damaged important system data, such as the Master Boot Record  (MBR).  If you suspect a faulty hard drive, it may be a good idea to backup and scan your hard drive for errors from another computer and  possibly consider buying a replacement.  Trying to repair a boot problem on a damaged drive can possibly lead to even more data loss, so backup your data before attempting anything.

The MBR and other important boot data can also be damaged by trying to install an earlier version of Windows, such as Windows XP, alongside Windows 7 and by third-party programs, such as viruses. In the case of a virus, it is recommended that you run a virus scan of the drive before attempting any repairs as otherwise it could lead to more data loss. It is further possible to achieve the appearance of damaged boot data by having the wrong drive partition set to active, which can be the outcome of an overly curious Windows user with administrative permissions.

Fixing the MBR and other start up problems in Windows 7 is most quickly accomplished by using the Windows 7 Installation DVD. If you do not have a Windows 7 Installation DVD however, you can alternatively use a Windows 7 System Recovery Disc, which we will show you how to create further down in this article.  If you do not yet have either a Windows 7 Installation DVD or a recovery disc, do yourself a big favor and make a recovery disc right away to avoid any unnecessary headaches down the road.

Fixing the Master Boot Record (MBR)

Step 1: Turn your computer on, booting from either your Windows 7 Installation DVD or Windows 7 System Recovery Disc.  Remember, you may need to change the boot order inside your BIOS to have the your DVD drive boot first.

Step 2: After the installation or recovery disc loads, if prompted, select your language settings and then continue.  If you are using the installation DVD, when prompted by the following screen select Repair your computer.

Step 3: The computer will take a moment now to scan itself for any Windows installations, after which you will likely be given a choice to select which installation you wish to repair.  Select the appropriate Windows installation from the list and then continue. If by chance a problem is detected in one of your Windows installations at this initial stage, the system may also ask you if it can try to repair the problem automatically. It is up to you if you wish to let the system try to repair itself, but otherwise just select No.

Step 4: Once you have reached the System Recovery Options screen, as shown below, you will be faced with a list of choices that can aid you in repairing a damaged Windows 7 operating system.  If you wish to try the Startup Repair option first, it is often successful in automatically fixing many different start up issues, but in this article we will be using the Command Prompt option to resolve our problems manually. So, clickCommand Prompt to continue.

Step five: Now sitting at the command prompt, enter the following command and then press enter:     bootrec.exe /FixMbr

If successful, you should be greeted with the message The operation completed successfully.  That’s it!  Your Master Boot Record has been repaired.

While the above command does fix the MBR, and sometimes that is enough, there still might be an error with the system partition’s boot sector and Boot Configuration Data (BCD). This might occur if you have tried to install another operating system alongside Windows 7, such as Windows XP.  To write a new boot sector, try the following command:

bootrec.exe /FixBoot

If you are still faced with your Windows 7 installation not being detected during start up, or if you wish to include more than one operating system choice to your system’s boot list, you can try the following command to rebuild your BCD:

       bootrec.exe /RebuildBcd

The above command will scan all your disks for other operating systems compatible with Windows 7 and allow you to add them to your system’s boot list. If this fails, you may need to backup the old BCD folder* and create a new one in its place with the following commands:

        bcdedit /export C:\BCD_Backup
        c:
        cd boot
        attrib bcd -s -h -r
        ren c:\boot\bcd bcd.old

        bootrec /RebuildBcd

*Some users also find simply deleting the boot folder and retrying the above steps effective at resolving boot issues, but it is not recommended.

 

ANOTHER METHOD

 

How To Manually Troubleshoot and Repair Windows 7 Bootloader

 

Here are few tips you can try if the Windows 7 Install/Repair disk doesn’t find the problem and won’t able to fix the boot issue for you.

  1. Boot Windows 7 installation disc in the disc drive, and then start the computer.
  2. Press a key when you are prompted.
  3. Click Repair your computer.
  4. Click the operating system that you want to repair, and then click Next.
  5. In the System Recovery Options dialog box, click Command Prompt.
  6. Type Bootrec.exe, and then press ENTER.

Bootrec.exe options

The Bootrec.exe tool supports the following options. Use the option that is appropriate for your situation. (This works on all versions of Vista and Windows 7 Only)

You can Try the following combination:

Bootrec.exe /FixMbr

The /FixMbr option writes a Windows 7 or Windows Vista-compatible MBR to the system partition. This option does not overwrite the existing partition table. Use this option when you must resolve MBR corruption issues, or when you have to remove non-standard code from the MBR.

Bootrec.exe /FixBoot

The /FixBoot option writes a new boot sector to the system partition by using a boot sector that is compatible with Windows Vista or Windows 7. Use this option if one of the following conditions is true:

  • The boot sector has been replaced with a non-standard Windows Vista or Windows 7 boot sector.
  • The boot sector is damaged.
  • An earlier Windows operating system has been installed after Windows Vista or Windows 7 was installed. In this scenario, the computer starts by using Windows NT Loader (NTLDR) instead of Windows Boot Manager (Bootmgr.exe).

Bootrec.exe /ScanOs

The /ScanOs  option scans all disks for installations that are compatible with Windows Vista or Windows 7. Additionally, this option displays the entries that are currently not in the BCD store. Use this option when there are Windows Vista or Windows 7 installations that the Boot Manager menu does not list.

Bootrec.exe /RebuildBcd

The /RebuildBcd option scans all disks for installations that are compatible with Windows Vista or Windows 7  Additionally, this option lets you select the installations  that you want to add to the BCD store. Use this option when you must completely rebuild the BCD.
