Don't forget Spybot S&D, Spywareblaster, a good trojan scanner like Ewido Security Suite, anti-intrusion software like Pivx's Qwik Fix and for extra measure, lock down Internet Explorer with IE Spyad. All that should keep your computer clean and running smoothly.
I have Spyware S&D on my pc, along with Adaware (earlier version). It was too late by the time I discovered them and installed them on my pc. Whatever is on that pc, disabled my Norton AntiVirus, and some tools provided by Windows. Many times when I tried to run S&D or Norton, my system would shut down. Then it would pop up with a warning that my virtual memory was too low. I could not find the programs that were running and causing the problem. Time for the geek squad, because my HD now sounds like a coffee grinder.
I'd like to get my hands on the creeps who dream up these worms, malware, trojans, etc.
When my pc is fixed, the first thing I'm going to do is go back to my bookmarked threads, and install everything....probably including Fire Fox.
Thanks again for your help :-)
