Re: you may find this hard to believe...
Hard to beleive? Not on your life! I'm also running the 64bt. Ubuntu 12.04 lts., and guess what? I got the FBI virus too....no windows...but I do run Wine.
First I got the pop-up and it wouldn't let go of my browser...it had it locked up. So I shut the system down, gave it a few minuits and rebooted.
Things looked good, I was able to run system settings so I removed Firefox, restarted again and reinstalled it to see how that would work. As soon as I opened it up the pop-up came back.
Now, I was angry. My 12.04 lts install was fairly new so I decided to clean house. I repartitioned and installed from a dvd. I fired it back up and it all looked good ...no more pop-up! The next day I'm on one of my forums and my curser starts moving around on it's own!!! You ever fight with someone over control of your own machine? I won, and gave it a rest.
That night I received a phonecall. Whoever it was.. seemed unsure of themselves, like a new telemarketer on their first call. He mumbled something I couldn't understand, and then I heard him say as his voice got louder (it sounded as if someone was prompting him) "You have a computer..a Windows computer?" I said "no" He said "you have a Windows computer, a Windows compuer, it doesn't run good. I can give you the comands to make it run better." I said "What the h*ll are you talking about? I don't want your commands!" and I hung up.
The next thing I did was to get Clam TK running. I found 4 files and I deleated them. They were within /home/c/.wine/drive_c/program files (x86)/ This disabled Wine. So I reinstalled Wine. I was back on a forum writing a lenthy post and then my text started to disappear, the same way as if the backspace key on the board were stuck. I returned to my desktop and opened a junk text file I had laying around, and it started to disappear too. Now when I run Clam TK It shows up again.
I've also noticed that my spell checker has stopped working. Is there a section on this forum where I can get help? Clamtk shows a program residing witin the program files(x86 folder to be infected.
