Secondlife Search Issues Maybe Connected to Avast

Problems maybe connected to Avast and Secondlife search

(prior to that, Installed WIndows 7 Clean from upgrade disc), SP1 manually, ethernet card drivers, all Windows updates, then motherboard chipset drivers, video, sound, keyboard, mouse, Then Avast, then Secondlife, (with Avast shields disabled), restarted after the install, configured Avast to exclude everything second life, and still search comes up very slow or not at all inside the program

Any ideas?

don’t really wanna switch Antivirus programs like Secondlife peer to peer support suggested
