Somehow Friday last week I picked up a Trojan file named "wupdt.exe". It managed to get in despite A/V, Firewall and port monitors. I only caught it when it started trying to transmit and both my firewall and port monitoring software went berserk. I'm still trying to trace where I got it from, but it's probably not going to happen. According to info I found on the web, this little bug starts putting its feelers into your system and allows whoever sent it to remotely access your computer. I dont know if this works since I keep remote access turned off on mine. I tried the recommended ways to remove it, no luck. Finally I had to go in from my other Windows account, in safe mode, delete the file, then log into that account in safe mode and delete all registry entries relating to it.
If anyone has ever gotten this file and knows for sure where you got it from, I'd like to know. Perhaps it can narrow down my search for the source so I can be more alert next time.
Thanks!
