Roy,
With all my other things I have done, I did not mention one last job I had was to supervise 60 computer tech’s repairing for Dell, IBM, TDSB, SDM, Ontario Justice, OPP and such.
All this stuff controls your conmputer and really slows it down.
I would get my own antiivirus , I use a free one from avast.com and the newest version of IE to control the phishing.
Adaware will remove any spyware you need to take out.
The firewall will screw you up bigtime, and the perforamnce tuneups stuff will also slow your computer down.
Try to use as little as possible of each one of these.
