I did a scan with mcafee online and it didn't find anything. Makes me wonder about this avast.... I won't be using it again, I almost deleted the files!
I guess you get what you pay for....
Well, don't be this hard on AVAST, as it is known for it's good engine and few false alerts. Like Raman said, these detections could be as real as they get (i'm almost sure)....
Why do you trust Macafee online over AVAST home ? There is a big change that Macaffee just did not detect the possibel trojan...as AVAST has better trojan detection than Macafee....
Do a system scan with "Trends online " & "Panda online" also...
If they both say your safe...your are most likely not infected.
Also send a the "infected" files to AVAST for examination please..the virus experts will have a good look at these then.
