Since people are also having it, I might as well post it here also. It may not be the same as what other people are experiencing. But it has one common point: ashWebSV using high memory.
My case is different though. It memory usage jumps up to as high as 80Mb on some occasions after an update is done by Avast. In some instances, its average memory usage is around 30-40Mb, and this happens always after an update of Avast is done. I find it funny actually. The common factor: it always eats up memory ALWAYS after an update is done. Without the update being done or during normal operations, the peak that I have seen is around 20Mb. Which is normal. But once an update is done, memory usage goes up.
I usually fix it by pausing ashWebSv from the Avast Menu, then resume it. Then it acts normally again. It behaves the same on my Windows XP SP3 PC. Same fix as well.
As for my specs:
Core 2 Duo E7300 2.66Ghz, 4Gb RAM, 4Gb ReadyBoost, Intel DG31PR Mobo, using a Windows Vista Ultimate SP2.
For the security Software: Avast 4.8, Online Armor Free. I only use on demand scanners like MBam, SAS and ESET Online Scanner, as back ups. I have also disabled Windows Defender and Windows Firewall (from the control panel). So it basically just Avast and Online Armor running. As for the updates, Avast is always updated.
Perhaps the programmers can also check into this. o:)
