(Solved) Avastsvc.exe very high CPU and Memory usage
« on: January 20, 2014, 10:16:06 PM »
Hello. I have seen a few topics on this forum about this issue already. However, most of them were solved by uninstalling the old version with the avast uninstall tool, running avast celanup tool, and installing the new beta version.

I too had this problem on my machine. I tried what everyone else suggested on the forums. It didn't work. I still see random RAM usage spikes, to upwards of 1/1.5 GB's, which will then drop the the normal memory usage. However, when the memory drops, the CPU usage starts to go up, very slowly, until it reaches 100%. The only way to stop this is to deactivate the web shield, but not only is that a thing I don't really want to do, the problem appears again around half an hour after reactivating the shield.

Could anyone give me a hand here?

Thanks in advance.

Guys, please help D: . I think I have a older version of avast around here, should I install the old version, no big risk in doing so?

Have you tried a repair? Control Panel>Uninstall a Program>double click "avast">click "repair">reboot
You may need to reboot a couple or more times with a period of time (about 5 minutes) between reboots.
IOW...shut down>wait five minutes>reboot>shut down>wait five minutes>reboot. Give your system enough time
to load all services when you reboot.

Yes, I rebooted around 5 times yesterday (when I installed the beta version), plus a few today, as well, and there were time gaps between each reboot, it wasn't me rebooting right after the pc starting up. By the way, if I tried to disable shields, avast would just freeze until I rebooted, and I could not close it in the task manager.

Any other security software you have now or ever had?
If uninstalled how was it removed?

I never had any other security software on this pc.

I uninstalled avast by using avastclear and RejZor's cleanup tool.

At the moment, I had to uninstall the new avast version (through the same methods), and install 8.0.1483 (I had an old installer in my pc), or else I could barely use my machine.

1) Good idea to keep an older installer...just in case.
2) Did you have this issue with v2014.9.0.2011?

The new beta was supposed to fix this.

You may need to do another clean install of v2014.9.0.2012 beta so you can get to the set-up logs.

Oh, I'm sorry, I totally skipped over that. It's service pack 1.

On AIS 2014.9.0.2011 I had the AvastSvc.exe using much more memory than in v8, usually growing with time (up to 250Mb max) ... but I noticed that disabling the Webshield for few seconds and the reactivating (from Avast settings) actually makes the process shrink down to 7-10Mb... then it will start slowly growing, but it might help to regain little control of the PC ::)

I couldn't disable the shields, because every time I tried to do so when Avastsvc.exe was going nuts, avast would just freeze until I rebooted.

Add the two lines in your WebShield.ini

[General]
UseStreamFilter=0

Ok, I have done this, and I will report back in a while, hope it works!

Yep, this seems to have fixed it, thanks a lot!
