Earlier this morning, after a scheduled McAffee scan, I looked through my quarantine section and found the Autorun Generic!atr trojan on my K drive flash drive, a Cruzer micro. It had picked it up on the 20th, which was the first time I had inserted the drive into my pc since coming back from vacation, where I used it often on various pcs. A manual scan of my flash drive also found the Recycler virus W32\IRCbot.gen.a, which the autorun is apparently a part. Now, McAffee quarantined them immediately and subsequent scans of both my flash drive and my PC came up clean, but the question still bugs me. How did it get there. I haven't copied or moved anything except a couple of photos onto my flash drive in months, and a scan before I left for vacation came up clean. I must have picked it up on vacation. But I always thought that something could only infect a flash drive if something is manually copied to the drive. Am I wrong? Can they become infected by just being connected? This has me very worried.
It's a stretch, but could this be a false positive? I've attatched the log info below.
Peace out and God bless.
