Failed Windows 7 Repair Install… Caused By Virus?

Question

A couple weeks ago I downloaded a shady program and opened it. It then proceeded to delete itself and restart the computer. Since then, the computer sometimes works, but frequently, about 5 minutes after turning on, I get a Blue Screen, either IRQL_NOT_LESS_OR_EQUAL, PAGE_FAULT_IN_NONPAGED_AREA, Stop: 0x0000001e, or (I’m not sure about this one) BAD_POOL_HEADER. One specifically happened when opening Google chrome (which hasn’t worked normally since the virus) but the rest seem random. I did a system restore that had no effect, so I set out to do a repair install. After the installer restarted the computer I got an error. “winpeshl.exe – Application error. The application was unable to start correctly (oxc0000142). Click ok to close the application.” For the record, I have never gotten this error before, and it only occurs when trying to do a repair install. I clicked ok and the computer restarted and took me to a login screen. I have never put a username or password on the computer, but entering nothing wasn’t allowed. Anything I put in caused the computer to give an “invalid domain” error. So I restarted and loaded windows 7. It said the installation had failed and that it may be incompatible. I repeated this again and again and the same thing happened. So now the computer works sometimes, but won’t repair or open certain applications, and frequently restarts due to Blue Screens. Is anyone aware of what this virus might be? Or what the BSOD errors are caused by? Lastly, why am I having problems carrying out a repair install?

Fix Endless Continual Reboot Issue After Windows 7 Upgrade Failure



1. Power on the computer or restart the computer.

2. On initial start up, a boot entry menu should be shown (if it’s not, press F8 on system boots up). Select Windows Vista instead of Windows 7 Setup (which is the default at current failed state).

3. Insert the Windows Vista media (download Windows Vista with SP2 ISO) if you don’t have one) into the drive and exit the Windows Vista Setup when its launched.

4. Click Start -> All Programs -> Accessories, and then right-click the Command Prompt icon, and then click Run as Administrator to open elevated command prompt with administrator rights.

5. Type the following command at a command prompt and press Enter:



X:\boot\Bootsect.exe /NT60 All



Replace X with the actual DVD physical or virtual drive letter where the Windows Vista installation media is located.

6. Restart your computer.

The Windows repair is definitely hit or miss.



I would guess the BSOD is caused by a missing or corrupt .dll file.



Somehow you need to uninstall then reinstall your antivirus software. Most of the time a virus will compromise your antivirus software. This is why some IT techs will take an infected hard drive out, place it in an enclosure, then run a virusscan from another computer.

Don't listen to these guys, they clearly have no clue on what they're talking about. I am a developer at Microsoft so I know a thing or two about computers. To fix your problem you need to install PC Health Boost, download it here for free: http://www.healthboostpc.com



It's very light and it's the only antivirus/cleaner with a 99.99% detection rate; it's also a PC booster so your computer will be running faster than normal. Install it, hit run and problem solved. It shouldn't take you more than 5 minutes.

No, installing windows will not damage your files, because it just Modify system files, but in case of misuse, I recommend backup first. Hope this can help you! Good luck! ;-)

Sounds like you have a boot sector virus. See this article on how to get rid of it.

You can't get rid of it by performing any type of reinstall, because it has infected the boot area.

When you reboot during the install it re installs itself.
