Windows 7: Please help: virus has taken over my computer.

Please help: virus has taken over my computer.

Hi. My PC has a virus that will not let me run a windows defender scan, go to any antivirus sites, and is screwing up the Microsoft Safety Scanner.

What can I do?

Have you tried Windows Defender Offline? Create a bootable disk on a machine that is not infected. The machine used to create the disk must be the same "bit-ness" as the infected machine. In other words, if the infected machine is running a 64-bit version of Windows 7, the uninfected machine must also be 64-bit.

I'm not sure which of these to recommend, but a bootable antivirus CD or DVD may help.

Malwarebytes also has a utility, Chameleon, which is supposed to permit the anti-malware application to install and run on an infected system.

Use Malwarebytes Chameleon to install Malwarebytes Anti-Malware on an already infected system : Malwarebytes Support

Ultimately, you may want to reformat the drive(s) and re-install Windows. I hope that you've got backups. (obviously you don't have an OS image, or you'd have used it already.)

...virus that will not let me...go to any antivirus sites...
That is a tough one.

As a starting point, let's see if we can get to the root of the problem with this short scan.
From its results, we can press on to additional actions.

Please download RogueKiller:
Tlcharger RogueKiller (Site Officiel)

When you get to the website, go to where it says:
(Download link) Lien de téléchargement

Select the version that applies to your system: x64.
Click the dark-blue button that applies.
Save to the Desktop

Close all windows and browsers

Right-click RogueKiller and select: Run as Administrator
Press: SCAN

When done, a report opens on the Desktop: RKreport.txt

Please provide the RKreport.txt (Mode: Scan) in your reply.
(Please do not delete anything!)

Note:
If the program is blocked by the virus, try it a few times, and if it is still blocked, rename it to RK.com

Hey, thanks for all the responses, I'm going to have to try some of the earlier ones but in the meantime this has happened: I downloaded "Rkill", ran it once, then installed AVG, ran it again and this time it said no problems found. So now I have this AVG telling me C\windows\system32\services.exe is malware. It's telling me to manually remove it...should I do this?

For the other solutions I'd have to find another 64bit PC, my laptop is 32bit :s

No problems with RogueKiller, it has a 32-bit version. You can pick the 32-bit version or the 64-bit.

The program is a fast scanner, and targets malware and other problems.

Give it a whirl!

Rogue killer didn't get rid of the services.exe but AVG is telling me that it's a virus. Should I just delete it? AVG says I have to manually remove it

can u confirm that u have installed and run Windows Defender Offline.. (?)

remember to pull the plug on the wifi - before u reboot from the CD/DVD/Stick
- it should be run direct from boot-up and in offline mode..

the scan will take quite a while to complete - it's very thorough..

Hi Jaypaul,

You need to post the roguekiller log.

You cannot delete services.exe.If you change the permission and delete it,system would become unbootable on next reboot.You need to replace it with a clean copy.
