further protection
Tobmanp, you have already installed nearly all the protection you need. However you did not mention having an anti-spyware program.
Spyware, as you may know is not as dangerous as a worm or virus, bothg of which could delete and corrupt your hard drive files. However, Spyware, unless you are protected can sneak into your computer, obtain private information, snoop into the websites you watch and then pester you with banners and ads and slow down your computer. 90% of all computers become infected with spyware.
Experts like
www.spybot.com which is free and very effective. I like
www.adware.com product. I suggest you take a look at both and choose what you like best.
