As far as I'm aware of, Geekstogo doesn't provide much information for the common user about how adding more programs (specifically security programs) running in the background/realtime can use up some of the computers resources. I don't think Geekstogo recommends a program unless it has a small footprint, but adding many together can be quite a "drag" on the general all purpose computer. Many members probably don't have "fast computers" like some of us do.
Do you think this should be Noticeably noted in the Free Anti-Virus and Anti-Spyware Software thread and possibly Rorschach112's Preventing Malware and Safe Computing Guide?
I try to remember back when I was very new, trying to increase my security, and following some of the tips sure did improve my security, but my computer slowed down quite a bit too. A lot of the people that buy computers from me seem to only have a P4 maybe 2.0ghz processor, 512mb RAM.
