This page is intended to document steps you can take to clean up a machine that is suspected to be infected.
Windows
Without networking
If possible, checking the system without a network connection prevents any viruses or malware from doing anything "bad" while you're trying to clean it up. The disadvantage is that you can't download any updates first.
Disable the network
- unplug the network connection
Boot in "Safe Mode"
- reboot the PC into Windows Safe Mode, by pressing F8 as the machine starts up
- select "Safe Mode without networking"
run scans in Safe Mode
- with whatever software is installed (Spybot S&D, Symantec A/V or others), run a scan
- you won't be able to update at this point, or install new A/V software
With networking
- reboot the PC into Windows Safe Mode, by pressing F8 as the machine starts up
- select "Safe Mode with networking"
Linux
