The protection on my PC There are thousands of ways to protect your PC from problems and attacks. I have spent many years trying and testing software to have a relatively secure and smooth working system. All of the software I rely on is FREE and does the job very well.

Worms - A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well. Trojan horses - A Trojan horse is simply a computer program. The program claims to do one thing (it may claim to be a game) but instead does damage when you run it (it may erase your hard disk). Trojan horses have no way to replicate automatically.
