I'll let others chime in on other items, but http://www.ccleaner.com/ should be reviewed as well as EWIDO.
System and software: Dell P4 with 1.5gig RAM running Windows XP SP2 with all updates. Zonealarm Pro installed for firewall, virus scan & anti spyware protection.
I've known there was a problem for quite some time, but not exactly what the problem was. First, I'm not able to view source code on web pages. Second, my gmail account keeps flashing a "your cache may be full" message.
Today I used Google Desktop to do a search, and found at least 200 CACHED webpages on my system. I find this a major problem, because I regularly use the Internet / Tools / Delete Files / Delete also all offline content command to clear cache on Explorer and I clear cache manually on Firefox. Not to mention the fact that ZoneAlarm has an automatic cache function weekly.
So, where are all these cached pages hiding??? I'd like to clear them out.
