i am using windows xp and firefox browser. i have avira free antivirus and malwarebytes antimalware. noticed my browser was super slow, and earlier today avira informed me that it found 4 trojans.
updated malwarebytes and did a scan, it did not detect anything. (it seems that the trojan is in the mbam.exe itself?!)
next i scanned using avira, it detected the malware but was unable to remove them.
i posted a topic on the am i infected forum here http://www.bleepingcomputer.com/forums/topic458116.html
and was told that it might be false positives and to do a virustotal.com scan. none of the files were found to be infected. is it normal for avira to be sending false positives (like did it just make up the name of some malware?!)? is it possible for malware to migrate from one file to another? am worried there's still malware hanging around. any help appreciated, thanks!
