My OS is Windows XP SP3 and the current programs that I have and/or run: General/Registry optimizing and cleaning Ccleaner EasyCleaner Desktop Maestro Advanced System Optimizer Anti Spyware Spybot Ad-Aware SE personal Anti Malware Malwarebytes (Paid version) Firewall Comodo 3 I have 3 questions that don't all relate to this forum but I didn't want to start 3 different threads. 1) I need an antivirus program as I recently unisntalled AVG 8. I don't want Mcafee, Kaspersky, Norton, or AVG. I'm looking for a somewhat lite program within reason that doesn't slow my pc down too much. I'd like a user friendly GUI if possible. 2) I would like to monitor what programs are using what ports. I'm not sure if this can be done with the programs I already have as I don't know every nuance of them yet. If not, is there a small program to do that? 3) Are there any other programs that would be considered more lite or faster than my current anti spyware? I don't like having 2 antispyware programs for the same purpose. Are there any programs that could help my security a bit more? I don't want to slow down my pc very much but within reason would be fine.
