Yes I can second that. AVAST has been hounding me for 2 weeks to update, so tired of getting the messages and have my machine always being slowed down as it checks for currency of the AV version, I decided to install the recent AVAST version 2014.9.0.2011
WHAT A mistake … immediately after reboot my CPU is constantly hitting 100% CPU at nearly all webpages.
I would estimate that the CPU is in 100% region 10 x more often that with the previous AVAST version.
This makes browsing impossible and frustrating.
*** AVAST, I second the previous comment - PLEASE PLEASE get this right and stop pushing updates on the PUBLIC if you cant. ***
Your issue is different from what this topic is about, the issue discussed here is about the gradual increase in memory for the avast service and when browsers are closed this memory doesn’t release.
Please start a topic of your own for your separate issue, I would also suggest that you update your XP to SP3 as this is likely the cause of your problem.
I was having this same problem on my 2 machines at home. During start up I had my task manager open and a Trusted Installer process (C:\Windows\servicing\Trustedinstaller) starting running 2-3 minutes after boot. I let this run the first couple of times and right after it “automatically” ended Avast would shoot up to 100% CPU and have a memory leak that would go into to 2-3 gig range.
I have now ended the installer manually on both machines during start up and the 100% cpu problem has gone away.
Not too sure if the 2 are related, just too much of a coincidence to ignore that this “fix” worked on both of my machines. Both machines are running Win7 with all updates installed.
I have done a boot time scan and a full system scan on both machines and no viruses were found.
Download the latest version of avast! Uninstall Utility and save it.
Download the latest avast! version and save it.
Uninstall avast from Control Panel (if possible). If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
Run the avast! Uninstall Utility saved on 1 in Safe Mode. Boot after you’ve run it. Repeat this for any major avast! version you have ever installed/upgraded in your computer.
Install avast! using the setup saved on 2. Boot.
Register your free copy or add the license key for Pro. Or even upgrade your key from old versions.
Check and post the results. If, for any reason, you did not solve, try doing the step 3 in Safe Mode anyway.
Well I’ve seen no reports on the forum of this issue returning so you should be fine, there have been two full stable versions released since your problem occurred.
To be safe you should always make a system image before upgrading and if problems occur then it is simple to revert.
