Most computers either come with a set of disks to recover your computer to out of box condition or has a feature to make a set of recovery disks to correct problems just like yours.
They also have a D partition on the hard drive that has a recovery program.
There are several free programs such as Rkill, Malwarebytes, Superantivirus and others that don't cost anything except the price of a blank CD and the time to run them.
There are free antivirus programs you can download and run, just Google "Free Antivirus programs" and choose one.
Some ISPs will give you free antivirus programs just for subscribing to their service. In my case I am with Comcast and they supply Norton 360v5 at no charge.
Hi, My computer has been infected with a virus for awhile now and it's affecting overall performance. I'm throwing to much money into anti virus programs that aren't doing the job. I need to to scrub the hard drive and start over fresh. Can you recommend a product that can be effective and information on operating system installation? Thanks!
