I have pondered long on whether to post this here or in the Security forum, finally decided here.
My new system has
XP SP2 Firewall
CA Antivirus
CA Anti Spyware
CA Anti Spam
Lavasoft AdAware SE Plus
Lavasoft Ad Watch SE Plus
Spybot Search & Destroy
CW Shredder
On my old system I also had
AdsGone
Spyware Doctor
Registry Mechanic
Window Washer
CC Cleaner
I believe now it was overdone and slowed the system as most were resident, do I need over and above what I have? I am not asking for comparisons unless there is a significant hole or something not covered.
