My kids' computer has been infected with some virus and I need the basic steps to start cleaning this up. I read the post on downloading Hijackit and gmer, etc., but the PC cannot access the sites for this yet. Clicking on any program results in a message that the program is infected and a scan is started. Eventually the scan takes me to a webse for purchasing AntiVirus Scan ... sofwareea.com. How do I begin to clean this up?
