If you use a third-party application which adds restricted sites to Internet Explorer, you may have difficultly logging in to your AOL account when McAfee SystemGuard is running. If a large number of restricted sites are added to Internet Explorer, it can create a significant increase in processing overhead. This increase in overhead causes a timeout issue when the AOL login process runs and can prevent you from accessing your AOL account.
Besides Spybot, SpywareBlaster and IE-Spyad also use restricted site entries to prevent malware. The facility for placing sites in different zones and setting various security options based on those zones is built into Internet Explorer for your protection.
