Hi- I have a Dell computer with an Intel Celeron processor with 128MB of RAM and 996hz processor. I downloaded a Comodo firewall. Now I need anti-virus(preferably free) and spyware(preferably free). I checked the system requirements for Avast, AVG, and Comomdo anti-virus and they all require an Intel Pentium processor(or equivalent). Can I still get one of these products with an Intel Celeron processor? Or what anti-virus can I get with an Intel processor? I can't afford to get a new processor right now. ALso, do you know of any registry cleaner that I can download for free that will scan and clean my computer. One more thing, do you recommend more than one spyware program for a computer?
