What's an SR CD?
Power down the computer and turn it back on, immediately tap F8 untail Advanced Boot Options appear, then select "safe mode with networking"
Update your anti-virus definitions and run a scan, then download
Malwarebytes(it's free), install, update, and run a full scan with it while in "safe mode with networking"
See if this rids the virus
edit: I think I know what you mean by restore CD, you mean your installation disk...If your CD is not starting, then you need to go into CMOS and set the drive boot order so that the CD drive is set to boot FIRST...Power down the comptuer, turn it back on and when you see the VERY FIRST picture on the screen, press either F1, F2, or delete key....This will allow you to enter CMOS...Find the section that allows you to set the boot order of your computers drives and set the CD drive to the TOP of the list of drives....This make make the computer boot from the CD drive first, before trying to boot off of any other bootable devices on the system..Before you exit CMOS, be sure you save the settings, or else it will not work. But seriously, reinstalling is a little bit extreme at this point, try running the anitvirus programs first
