In addition to what you already have, these are all free and will find different things than the ones that you already have. Unfortunately, there is no ONE program that does it all but these will help.
Spybot S&D (download, check for updates, read the tutorial and scan often, it also does some blocking)
SpywareBlaster (a blocker only, download it, check for updates, enable it and leave it alone except for checking for updates occasionally)
SpywareGuard (similiar to SpywareBlaster but works in a different way and does not update as often for that reason.
Ad-Aware SE (a scanner, download, check for updates, read the directions and scan.
cwshredder (stand alone unit)(another small scanner for certain things, ALL other windows should be closed)
My computer is running very slow in relation to its previous performance. I have been told that it must be spyware and adaware.
I run Windows XP Professional.
I have Norton antivirus running and I also have Microsoft AntiSpyware installed. How effective are these programs to protect me?
Is Microsoft AntiSpyware effective?
Are there any online free programs that I can use?
Your advice would be greatly appreciated.
