It is well known by reading the posts that Avast. 2015 slows sharply web browsing. In addition the site av-test.org seems to confirm these different posts. >:(
Computer’s performance is significantly reduced to the point that even with a paid licence ( available end 2016) I uninstalled avast! and put a competitor instead.
My question is simple : when will the team has planned a Avast SP2 for Avats! 2015 to sustainably and efficiently solve this performance problem. ;D
Avira tested for 2015 in terms of performance difference is obvious.
With version 2013 & 2014 Avast I had no such problems and very frequently now I must use CTRL-ALT -SUP to go kill the process, avast is clearly the cause of slowdowns.
Regarding Internet browsing there is a strong slowdown.
I’m having similar problems. Ever since the 2015 version has been installed, my PC is hesitating, browser is freezing for seconds at a time and Task Manager frequently shows Avast processes taking up to 50% of the CPU. This is unacceptable. You can’t blame this on browser add ons. Before 2015, everything worked fine. Mine is so bad I want to downgrade to the last version. How is the easiest way to do that? I’ll wait until a better version comes out before upgrading again.
I’m running Windows 7 Home Premium. It’s not just the browser that freezes up. It will make any application freeze for seconds at a time. Even solitaire freezes. Here’s my CPU usage.
I solved this problem by noting that the AvastSVC CPU consumption dropped from 50 - 60% to very low values when I disabled the Firewall in the Active Protection menu. Not the optimal way, granted, but lacking a better solution…
