Beginning 4/15/09, viewing craigslist will yield a web page cannot be displayed screen with an attempt at any address. Logout and establishing a new session will work normally with any address until craigslist is addressed, then all subsequent addresses will not work. If I do a system recovery, I can access craigslist once successfully, then it goes back to page cannot be displayed again. I cannot open a ticket with avast. Login yields a blank page. Win XP SP2, IE Explorer 6, Avast 4.8.1296, VPS 090416-0, dial up via netscape, no other virus software. Thanks
