The sript blocker will stop certain scripts from harming you computer. However there is no software that can stop/remove all spy-/add-/malware. To make your system as safe as possible you need to have/do a few things.

  1. keep your os up to date http://windowsupdate.microsoft.com
  2. Use good anti-virus software - Avast :wink: and have on access protection on
  3. keep Avast up-to-date ofcourse
  4. Use a firewall. Preferably a router with build in one. But if you can’t afford that, you can use the free edition of ZoneAlarm www.zonelabs.com
  5. There are progs especially designed to detect/remove spy-/addware like cwshredder, hijackthis, ad-aware, spybot s&d and TheCleaner.

    All, except for TheCleaner are freeware.

6)Getting infected or not has also to do with the way you use a computer. Setting up the system correctly will make it more secure and less vulnerable to infections. It is therefor needed to read the manual of progs/operating system to learn what is possible and how to set them up correctly. Espescially when multiple user are using the same computer. If you have windows XP/2k look at the next link for many things you can change to make the system more secure. http://www.markusjansson.net/exp.html

I hope this information will help you to keep the system clean and let you enjoy the use of it.
