I have Slipstream web accelerator and a dialup connection. It’s never really started very well on it’s own, so I finally disabled it from starting automatically and put an icon in Quick Launch. I dial up and then start Slipstream. It’s worked good ever since.

I did have a couple issues directly related to Avast but they were easy to fix. Slipstream is a proxy and uses port 5400 so I had to add 5400 to “HTTP Ports” in the Avast Redirect Settings and right below that “Ignore local communication” has to be unchecked or else the Web Scanner won’t scan. And right below that I had to uncheck “Ignore local communication” in the Mail settings to get the Email Scanner to work.

It might help if you could go into a little more detail about your system and what you mean exactly by “quit working.” What kind of connection to the internet do you have and what web accelerator are you using?
