I am facing a problem for a couple of days now that seems impossible to resolve...
WinXP SP2 machine
I was using outlook and had the preview pane enabled. as soon as I opened my inbox folder the first email appeared. for my bad luck, it contained a virus which my Symantec Antivirus (full version: 10.0.0.359, with updates on 20/5/09) detected. I deleted the email, unfortunately it seems my system has been compromised.
Keep getting reports from my antivirus that it found and successfully deleted files like "hacktool.rootkit", or "downloader".
Apart from that, there was a file in one of my folders in Docs&Settings under a folder named "nameOfFolder.exe" which I could not get rid of - I turned to safe mode and removed it, but it came back up on restart to normal mode. I finally managed to remove it today by first renaming and then deleting (!).
Moreover, there is a file in my system32 folder with the name bootok.exe which from what i read is a virus/trojan - which again I cannot get rid of: i can delete it, but it keeps coming back.
Finally, I cannot go to my registry editor.
I have updated my antivirus but in every scan my machine appears clean...
I also scanned with malwarebytes' antimalware: clean.
also with rootkit.reavealer: clean.
tried also to run HiJackThis, but it cannot run...
