First of all i try to show all super-hidden files by using tools such as USB Disk Security / RRT (www.sergiwa.com) or by using ACDSee program where i use to see hidden files to remove viruses etc

After ^^ these steps, "Hijack this" tool is used to remove / delete viruses. Registry Cleaner program like "Tune up utilities" to clean registry as well as temporary files.

In last i create new user and delete the previous one if necessary
