Like Antivirus..

we try to keep up with the latest. Norton's was a waste of time and money. We're also using Avast, though truthfully there's something on here at the moment which affects Outlook Express - won't let me open or delete certain messages (all different sources) without freezing OE or the whole PC. Also there's a pop up which keeps picking up the first website name we open and it keeps popping up. We do have pop ups disallowed but it still happens. And we also have a firewall (Sygate). Just can't find what's on here :(
