This last week I’ve noticed my Pc has been slowing down at certain points, I first suspected a virus of some sort so did a full scan with Avast, malware Bytes , and Super Anti spyware, along with Eset and kaspersky’s online scanners which all came up with nothing. The slows downs usually happen when I’m using netflix or low intensive tasks and idle states.
I opened up task manager to see if i could find anything wrong and everything looked normal even though almost all my ram and 99% of my cpu were been used on idle. The only way to restore it to normal is to restart the computer.
Knowing I would be watching Netflix i decided to download a more thorough task manager and got the Process Explorer, this is what it found when i checked it. (pic included) as you can see Avast alone is using 98 percent of my Cpu power and looks to be the main culperate in slowing down my pc.
Other than netflix what are you doing when this high CPU is high ?
The netflix would be streaming and I’m not a netflix user so I don’t know if this is cached to a temporary file, which is constantly updated. This could cause avast to be continually scanning these changes.
When this high CPU is experienced, is the avast tray icon rotating ?
It is possible that it may be stalled.
What avast version are you using, free/Pro/AIS/Premier the latest version is 9.0.2013 ?
It’s just netflix and other random tasks like Steam and Origin not doing much in the background, I just looked and I do not have the latest Avast installed its was from 2009 I think? which is strange as I downloaded it from the main site around 6 months ago after a fresh install. I’m sorry I didn’t notice if it was roatating as it’s hidden in my tray. next time it happens I’ll be sure to take a look for you. Thanks
Personally I wouldn’t wait for it - I would recommend that you update to the latest version as there were some fixes between your version and the latest one. If this did resolve it then you aren’t chasing an issue resolved already.
It is probably better to do a clean reinstall again.
Download the avast! Uninstall Utility, avastclear.exe find it here and save it to your HDD.
Now uninstall avast! - using add remove programs, if you can’t do that (as appears to be the case) start from the next step, reboot.- 2. run the avast! Uninstall Utility, it will request it be run from safe mode (and will handle the boot into safe mode), once complete reboot into normal mode.- 3. install the latest version, reboot.
Note: save the copy of avastclear.exe so it can be reused as some users are reporting that after running it, it is self-deleting.
