Really? So, Malwarebytes and Avast will not work properly if they are both installed?? Hmmm. OK, I did the boot scan, though I had to take my daughter to work while it was running, so I didn't see everything it caught. Now I have some questions about the types of files they found.
It found several files that baffled me. Several were of this variety: {OLE archive is corrupted} and {ZIP archive is corrupted}. How do Zip files get corrupted, and what is an OLE file? And what does Avast do with these corrupted files once it find them?
Also, here is another file Avast found--can anyone tell me what they do and how they could be affected?
"File c:\Documents and Settings\[name]\Application Data\Sun\Java\Deployment\cache/6.0\35\31a0f1e3-1a85421a|>c.class is infected by Java:Jade-A [Heur]" -- this one gave me a number of options, so I selected "Delete." What is "[Heur]"?
Any help would be appreciated--if there is any way to tell how this was downloaded and from where, that might help. My son did have this computer before me, so it's possible that a virus affected the system when he had it.
I'm just curious about all these files--how they get corrupted, what do they do, etc.
Thank you so much for your help--it's amazing that Avast was able to find what other anti-virus programs have been unable to find! Thanks again!
