offshoreclicks,toolbarxxx,i-lookup,teensguru

Four sites (offshorclick.com, toolbarxxx.com,i-lookup-com,teensguru.com) that I have marked in the "Restricted Sites" keep getting unchecked.

I go back and check them again, and a few days later they are unchecked.

I have been running "AOL Spyware Protection" and that found the above 4 files as being part of "2020Search", so I quarintined them.

So what is causing this?
Is is SpywareBlaster error?
How do I fix it?

 

have you got pest patrol if you have then it could be pest patrol given false readings
