So has this Win32: Malware-gen thing been confirmed as a real threat or a false positive?
I'm still suspicious of it but I've had three different files being reported as Win32: Malware-gen by Avast and only using boot time high snesitivity scans. I used Avast's delete option to get rid of the first reported problem which was a file in my Restore Points folder. A new boot time scan afterwards was clean.
That was last weekend. This weekend I did another boot time scan and very quickly up came another case, this time in my Docs & Settings > All Users > Application Data folder. This time I sent it to the virus chest. Later that day I did another boot time scan and there was another reported Win32: Malware-gen this time again in the Restore Points folder but a different file from the previous deleted case.
As I knew where it was I found the folder and used both Spybot and then Malwarebytes to scan the folder. They reported nothing. I then tried a Quick Avast scan and that, which like the Full System scan I'd also done and had shown up nothing previously with this this or the earlier 'infections', was now also reporting the file as a virus.
Again I put it in the virus chest, repeated a boot time scan (clean), Quick scan (clean) and a full system Malwarebytes scan (clean). This morning I did a boot time scan at Normal sensitivity and that came out clean too.
That's where I am at but now no longer sure what to trust and not looking foward to doing a boot time scan at highest sensitivity in case it throws up another Win32: Malware-gen report somewhere else.
I thought I'd check
