about averything including Spyware Doctor which is good for mainly Spyware. You should also use Spybot S&D which is free for spyware. Neither of them protect from viruses so you also need an antivirus program. There are a few free ones that are good such as AVG and Avast. Trojans and viruses are similiar but not the same. Ewido, which is also free after the 14 days trial period is one of the better programs to protect from them.
I use Firefox to access the internet and am wondering if any of the spyware protectors or anti-viruses out there that work with Firefox. Currently I'm using Spyware Doctor, but am not sure if it is even doing anything with Firefox. Also, does Spyware Doctor act against Viruses? I read it protects against Trojans, which are viruses, so do I need a separate Virus protector and if so what would you wise folks out there recommend (one that of course would be compatible with Firefox)?
That's probably plenty of questions for now.
