Okay, this is kind of a long story, but I want to give details in case something is important.
Last night I was downloading a MMO game (massively multiplayer online). The download was going to take a while so I went to bed. This morning, the download was complete, but Symantec endpoint v11 had caught a tracking cookie and a virus called W32.SillyFDC and quaranteened it. After some research, I learned that this virus can come from a flash drive and is associated with a program on such a drive called "autorun.exe". I had noticed this file on my flash drive some time ago, but didn't think much of it; I thought it was the autorun feature of the flash drive. As a result, I don't think the virus came from the game I was downloading, but I don't know why it would suddenly pop up in Symantec while I was downloading.
The game apparently downloaded through something called DNA, which I believe is a bit torrent program or something, but I had no intention of using P2P at all. DNA stayed running in the background until I shut it down by right clicking the icon in the start bar.
I saw reports online of people deleting the virus like Norton tells them (and me) to do, and saying the virus damaged 50 registry entries, subsequently shutting down their capability to access system tools, regedit, among other things, so I decided to come to you before doing anything.
A full system scan with Symantec revealed nothing, the virus is still in my quaranteen, the flash drive is still attached to my machine, and has three hidden files I do not recognize; "recycler" which is associated to the virus and seems only to mirror what is in my recycle bin, DRMv1PM.lic, and WMPInfo.xml, neither of which I recognize. I have not seen the mysterious "autorun.exe" file in my flash drive since all this started going down.
I have run Spybot S&D and it found nothing of note. Maybe I got off lucky?
I have no idea where this virus in my flash drive has come from, since I only use it in my own computers, not strange ones, but I believe it may have been there inactive for over a year. Or maybe I'm just cracked and the virus did come from the download. I have no clue and I am not very knowledgeable about the complex workings of a computer.
Below is my HJT logfile, as you will see, DNA is a running process on my computer, though I did not ask to download it, I think the downloader for the game did it. I thought I shut it down though, I do not know why it is a running process. I think I might need help deleting this program. Thanks in advance for your time and help!
