The following site describes about disinfecting your computer from virus, spywares and adware. It also describe about how to immune your computer to avoid another infection.

The following is just an introduction of that website (Copied from that site itself)

My name is Dave Dockery.

I've been removing a lot of viruses & spyware from my clients' computers lately.  This junk has been growing increasingly tenacious.  No longer can you run a single utility, and expect it to protect your computer.

I give a 6-hour seminar entitled Defending Your Computer which details a method of cleaning and immunizing your system.  This website is a resource for that seminar.  All of the utilities that I use are linked from this web, and all of them are free to use.

If you want to disinfect your computer or immunize your computer this site will be a good reference.
