Currently, I have installed zonealarm's free firewall, spybot search and destroy, the free avg virus scanner, and the free adaware program. I am also using firefox with noscript for my internet browser. Are there any other programs I should consider downloading? I remember the guides mentioning that multiple programs for the same function (i.e. multiple virus scanners) are beneficial since one may detect stuff that another wouldn't; however, the guides also said that multiple programs may weaken and/or fight with each other. So, currently, I'm not really sure what else to add?
Any thoughts? I'm sorry if these are somewhat simple questions.
thank you
