Avast 7/8 high cpu usage during video (browser?) playback

Hi guys.

I'm an moderate-advanced user, and i often help my friends with malware and clean their systems, when i do that, i install Avast on their decent but low end systems, still more then capable to handle modern AV, core 2 duo + 2GB ram ect.

Now, when they are using Avast, they got cpu spikes, all 3 of them, including me! so this can't be configuration/os related, no way!

To recrate the problem i reinstalled Avast on my pc, while my pc is very powerful, and total overkill, i5 @4.8Ghz constant frequency, and Samsung 840 pro SSD, i still mind this spikes which should not happen, at all.

It happens always, when you fast forward, pause-play, or even during normal playback, but at random times. I have no browser protection installed, neither they had. Very low junk installed very low number of addons, maximum performance tuned pc, with 8GB of ram as well.

This was exactly the same on version 7, and its still not fixed yet. Its same on fresh os/used, nothing changing.

Any toughts?

 

I like the newer versions of Avast a lot. I recommend the program to people often, along with a few other AVs. Avast uses very little ram, but I would consider the program only average in terms of cpu & disk usage.

 

dazed1, interesting.

Would you mind helping us analyze the problem by doing the following?

1. While the AvastSvc.exe CPU usage is high, right-click the process in Process Explorer, and select Create Dump -> Create Full Dump

2. Compress the resulting file (e.g. with ZIP) and name it uniquely (e.g. dazed1_dump.zip)

3. Upload the file to ftp://ftp.avast.com/incoming (write-only anonymous access).


Thanks

Hi, thanks for the help, you got pm!

 

Bump!

 

Not using avast at the moment (in fact no av installed at present) ,but i notice that when playing vids /flash stuff through firefox ,the plugin container for firefox uses around the same cpu usage 17.7 % no matter what spec pc you have.Maybe avast service is acting like the firefox plugin container only in chrome? especially as it has web scanning.
