Here's a very weird glitch I found shortly after updating to 4.8.1187. As the title says, avast! only shows 5 providers running and has the Internet Mail Provider stuck on "waiting for a subsystem to start" when it normally never had to do that. I didn't really notice this before, but after doing a defrag (using vista's built-in function) and a reboot shortly after this suddenly hit me. A screenshot of this exact status in the On-Access menu shows this in a bit more detail.
On top of this, a weirder related problem involves trying to re-initialize or stop all the providers. The message "Stopping Internet Mail" pops up first even though it shown to not be running at all. Then nothing happens after that--you still see avast! with 5 providers running! This really confused me, so I waited a bit, and then sure enough all of the other 4 providers shut down as well at the same time after a significantly long wait (outlook one does not apply to this case as I wasn't running it). After this case I tried starting up the providers again and the same deal happens--only the 5 providers activate and the Internet Mail one resumes its status of "waiting for a subsystem to start". I will try a reboot in a bit to see if this temporarily "fixes" it, but since this was rather out of the blue, it might be harder to reproduce. If anyone has any immediate requests for some information I'll see what I can do. Also, there are no error messages in the avast! log viewer.
