Hello. I signed up on this forum to express that I'm having the exact same problem as ralan and it just started this morning. I've been using avast free for years and have always updated the program when prompted to do so. I run XP pro service pack 3. Like ralan I had no problems with 5.0.545 or any other previous versions. This has to be a problem with 5.0.594. I certainly hope the developers will fix this issue.
