Virus Won't Let Me Install Anti Virus.

shahbaz200 · Nov 22, 2014

OS = Win 7 32bit

I didn't had any anti virus installed and I think I got infected by flash drives. When ever I try to download A/V either this happens:

Or A/V setup gets locked:

I have tried many times same happens. I have dual boot with Win 8.1. It works fine but If I install it on 8.1, it won't start in 7 and will give me some "blah blah not found" error. If I get installation work, in the middle it will show error "can not open blah blah file, access denied". I don't know what to do, not only it locks A/V exe setups but many other exe stuff too. Any idea?

From another machine or OS, download a boot antivirus solution. Kaspersky Rescue disk, for instance.
Boot from that, and clean as needed.

I'm not sure what type of computer you have so you may have to do some research on how to, but if you boot into safe mode, you may be able to install an antivirus that way.

I would seriously do a clean, fresh, and nice smelling install of Windows on that 'puter.

Even though most of these AV companies have tools to scan before boot I would honestly just backup everything that's important re-format and re-install Windows 7. I don't think I've ever seen a PC work "as new" after removing serious malware from it. Best option is always to re-install.

In case you're not going to do that then these tools should help:

Kaspersky:
http://www.kaspersky.com/virus-scanner
Check out the Virus removal tool and the Rescue Disk.

AVG:
http://www.avg.com/ww-en/virus-removal
If you know what infected you they offer the tool to remove it.

Norton:

Try power eraser and if that doesn't do it try the other one.

ESET:

Read the instructions and try their removal tool and see if it works.

Agreed. Given a particularly bad virus, wipe and reinstall.
Going through the whole process of scan and clean, with several tools, will probably take longer than just a reinstall.

Didnt saw there cause I was busy, did boot scan with avg scanner, detects few threats but still same issue, scanned system with MBAM in win8 still same.

No, safe mode doesn;t fixes issue.

WhiteDove2014 :

Too much data, can't do fresh install at the moment. And I know it could fix issue easily.
