I am a novice with an XP computer using a DSL internet connection with the IE6.0 browser. The computer has had Norton Internet Security and Anti-Virus protection together with E anti-virus from SBC and a built-in firewall in the 2Wire internet connection box. Everything worked smoothly until I downloaded Spybot and SpywareBlaster 2 days ago. IE runs and connects to some web sites but not to others: Microsoft (so no updates), my bank accounts, my health insurer, etc. I am a novice at this and not competent to work out my own fixes. What can I do?
