Unknown Trojan attacking computer--please help!

=Bobby Baldwin;387588]All right, I was online a few days ago and I was trying to watch a video on a web site, and it said I needed to download something before I could watch the video, so like an idiot I did, and pretty much instantly I started getting a popup that says,

"Your computer was infected by unknown trojan. It's dangerous for your system (Critical files can be lost)! Click OK to download the antispyware program to clean your system! (Recommended) "

Since it doesn't look like a normal windows vista type popup, I've just been exiting it, and not downloading what it seems to want me to.

I've run my McAfee antivirus and also AVG free, but they don't come up with anything... When I ran spybot it came up with something called win32.Agent.gvu and when I tried to get rid of it, spybot never showed it again...but the popups still aren't going away, so I'm not sure if that's my problem or not.

I'm kinda worthless when it comes to computers, besides doing the basic stuff, so if anyone who knows a bit more about them would be willing to give me some ideas, and help me out, I'd really appreciate it. My computer is running slow, both in booting up and when I'm on the internet....and yeah, I have no idea what I'm doing...hopefully someone out there can help me get this straightened out.

Thanks, Bobby[/QUOTE]

I have a vista....I have that same exact problem. I did as was told to bobby, but I get stuck when I am to delete msvid... I turned off the user protection (under control panel) and reboot and everything and I cannot manage to delete the bugger. It keeps telling me I need permission. Please help me!!!! I haven't had a virus/bug in over 5 years and now this! It's really getting to me because none of my detection software can get it I'm really looiking forward to your help in this.
Thank you,
Christine

We need to get a look at things. Please read this topic, install the latest version of Hijackthis, run a scan and save the log (you can close it for now). Then, download and run Deckard's System Scanner and post the main.txt log here.
