Hi ppl, Been reading a lot of articles about how various tojans and spyware software attacks your computer. I've been meaning to buy/download one of these softwares off the internet to act as a blocker/firewall etc. Since most of them are 50-60$ wanna know which is a good bet and if anyone is currently using which is it? and how satisfied are you with it.............some of which i have checked out are spyware doctor, adware, norton internet security and countless others....... Also is anyone using a registry cleaner. Tell me if it is really usefull and why do we need it? Thanks PS. If this thread already exists please tell me and i will not post in this anymore.
