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 .

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.

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.
