I have virus but can't find it

Hilsbils_2

I have windows 7, 64 bit

it has been getting slower and slower on start up, lost the link to my graphics card (which I reinstalled) and lost the link to open outlook (which I reinstalled)
it then starting hanging & looping on start up and I had to do a command prompt with my recovery discs to bootrec.exe, since then I have been able to start up although its very slow and its now lost my graphics card again (I haven't tried outlook as I don't want my emails to download)

I have followed the thread about removing malware and this is what has happened so far:

• I couldn't download malwarebytes until I renamed it
• Ran malware bytes but it crashed the machine
• Lavasoft AdAware crashed the machine
• I ran malwarebytes in safe mode (full scan) and it didn't find anything
• Activescan from Panda security found 6 infected files that turned out to be tracking cookies but wanted £9.99 to remove them
• Ccleaner found 1,000 mb of files mostly ie temporary files and cookies which I deleted
• Spybot didn't find anything
• Superantispyware couldn't launch
• Housecall, tredmicro didn't find anything with a quick scan so now I'm doing a full scan

I wondered about using hi-jack but I'm not 'techie' enough.
I assumed my pc was automatically saving restore points (as thats what it says it should do) but when I have tried to go back to a restore point it says there are none saved, so I think I should try & do a restore point now even though I've got problems so at least I have something to fall back on.

I'm assuming this must be a virus, does anyone have any suggestions please? thanks

Download this and save it to your desktop.

http://public.avast.com/~gmerek/aswMBR.exe

When you've downloaded it...

• Right click aswMBR.exe > "Run as Administrator "to run it
• Click yes to the prompt to download Avast! virus definitions.
• Set the AVscan to Quick Scan, & click the Scan button.
• When the scan reports "Scan finished successfully", click Save log & save the log to your desktop.
• Click OK when prompted. aswMBR.txt & MBR.dat will be appear on your desktop.
• Click EXIT.
• Copy & paste the contents of aswMBR.txt & post it here.

Don't click to fix anything yet, just post the log.

How old is the computer? Is it a laptop? If it is a laptop that is around a year or more in age, chances are the faults are down to a blocked up heatsink which is putting the laptop in "limp home" mode to prevent the CPU being overcooked and you'd start getting data corruption when the machine shut down.

Yes it is a laptop not quite 6 months old.

I have downloaded aswMBR and 3 minutes into the scan it has frozen the machine at line 383 Scanning: c:\windows\bfsvc.exe

I couldnt save log but have written out the lines up to then, if it will help I will type them out. I will try and rescan if I can get the machine rebooted

I would say back up important stuff and do a fresh format and install of Windows

I have backed everything up, I was just hoping to sort the problem out without having to start from scratch

Run it without the Avast quick scan. It should only take a miute or so.

• Right click aswMBR.exe > "Run as Administrator "to run it
• Click NO to the prompt to download Avast! virus definitions.
• click the Scan button.
• When the scan reports "Scan finished successfully", click Save log & save the log to your desktop.
• Click OK when prompted. aswMBR.txt & MBR.dat will be appear on your desktop.
• Click EXIT.
• Copy & paste the contents of aswMBR.txt & post it here.

Might be quicker than faffing about trying to find a needle in a haystack with all these attempts you have made to no avail

I didn't get the option to click no to quickscan, so I put down to scan c:\ (was that right?) so far it has been 12 minutes

Could have installed Windows by now

Would be handy if you could run HijackThis and post the log file.

Notice you have Lavasoft AdAware which I wouldn't use these days.
