Information Security Stack Exchange is a question and answer site for Information security professionals. It's 100% free, no registration required.

One of my friends windows laptops (which I don't have access to right now) has in the recent past had a virus (where .doc files were converted to .exe files) which we dealt with.

Now when she right-clicks a folder to "send to compressed file" instead of creating a .zip file it creates an image file (jpg/png variety - will find out which). Is this known behaviour of a virus? I can't find anything anywhere about this kind of behaviour. Avast is not picking it up as a virus, but I can't imagine it being anything but a virus.

Where do I start to fix this?

I would assume, since you say that you dealt with the previous virus, that you "nuked it from orbit". Is this assumption correct, or is your friend's laptop still presumed infected? It is definitely one of the two. –  AviD Mar 13 '13 at 12:45
I didn't nuke it from space, no! Just used avast to remove the virus, but yes that might be a solution! –  Matt Parkins Mar 13 '13 at 15:09
No, the issue is that you know there was a severe problem (the virus infestation). You did not deal with it properly, and are trying to ignore it. Again, I don't know that it is caused by the virus, but I find it pointless to deal with the little things (like checking oil) before dealing with the big, critical things (like the cracked engine). Here's the thing: If it is a virus / malware issue, in some way, the advice you will get here is as I've said: Nuke It. If it is not virus/malware, the question would be off topic here... –  AviD Mar 13 '13 at 19:49
