Spyware Guard is a real-time protection tool that monitors certain events and then acts to notify you that these events are taking place rather than prevent specific threats. SG will notify you of any event attempt to change the browser home page - it makes no judgment on whether the change is good or bad but leaves the decision up to you to allow or deny it.
Can you describe these pop ups that your getting?
What OS (Win XP/2000, etc) are you using? What type of anti-virus are you using and when was the last time you ran a scan? Have you performed any anti-spyware scans? Have your tried doing your scans in "
SAFE MODE"?
You need to start there first. If you don't have any anti-virus or anti-malware programs see BC's
List of Virus & Malware Resources and at least scan with
Ad-Aware and
Spybot S&D. In #4 there is a list of several free online anti-virus scans which you can perform.
