Hi guys, so I'm also joining the list of "victims"
First thing I did coming back from holiday is to update avast program to version 4.8.1351, and then troubles started immediately.
I'm using Firefox and am crazy about tabs, I often open 20-30 at a time. Following this, computer started to slow down and I noticed that ashServ.exe is taking about 700MB of virtual memory, which makes my computer swap immediately since I only have 1GB of RAM.
Obviously this looks like some kind of memory leak, it's the first time I've seen this kind of problem in avast.
Reading all the posts I wanted to say that I don't believe they don't take the problem seriously, just there are a wide range of hardware, many different software could interract and cause a trouble. Moreover, the fact that we're a few here having a setup that reproduces the problem doesn't mean that it could also be reproduced easily on setups used by the avast team. Working as a QA engineer, I can tell you this is not always so obvious, even when you have dumps or logs for analyses
So, I'm also impatiently waiting for the new build, but I do believe that avast is a software of the highest quality.
Let the programmer who never makes bugs throw the first stone
