your root kit is fucked :s
try to get as much info and then reinstall your OS .. your cached memory ( prob 8k,16 or 32k ) space as well.
after that i would re-config my router ( call your ISP, better safe then.. )
Ubuntu 10.10... is bootable from your cd drive. ( it's a linux OS, but very simple )
If you have time, give it try before you format.. you could prob save some stuff and TRACE that shit
It may not be that bad. The point of these fake scanners is blackmail. The user will be asked to "upgrade" to a paid version in order to have the threats removed. In the mean time, a package would have been left behind that constantly reminds the user of these uncleared threats every time they use their PC.
A friend of mine got one of these, and I was able to identify and remove it using some online research and an appropriate tool from a well respected vendor.
The step by step removal guide is not for the faint hearted though, and some steps are not needed depending upon the exact variant installed.
One trick is that some files are held by an active process, and cannot simply be deleted. This has to be done either by adding script to "autoexec.bat" (which the tools can do for you), or booting from a CD or rescue disk. These then allow removal of the files at boot up.
If a rootkit has been sneaked in, this can be detected by the newer security packages, and removed.
One sign of a rootkit, or something else, remaining is that the scanner will find it's way back onto the PC after a couple more reboots.
At the very least, there is an opportunity to rescue your data before reinstalling the OS. The rescued data should then be subjected to a deep scan by a good security product before being allowed back onto the clean install.
Good security in the first place would normally prevent this scanner from installing it's package, but it might still try it on by showing a webpage that looked like a warning from your OS.
Security packages have a list of known websites like this, and create a blacklist in the registry which prevents these known sites putting ANYTHING on your PC, as well as giving a clear warning before allowing the browser to load the pages.
