100% cpu

Dear Forum,

I have been using avast anti-virus free for a number of years, but now I have a problem

I am using a netbook, Lenovo, windows 7, Intel celeron cpu1005m, 1.90Ghz, upgraded to 6Gb ram (from 2Gb). I am using the netbook temporarily whilst my laptop is having the battery replaced. I have had to send it away and the shop says it could take a month.

I have just got back from the shop, and I found that the cpu was running at 100%. On investigating the processes I discovered it was the avast service. Then I found that if I switched off the web shield CPU usage was mostly fine - have to not open too many tabs on google chrome.

Before I went to have the ram upgrade the netbook was slow but normal cpu usage.

I am not happy about not having the web shield.

Does anyone have any suggestions?

Hope you are keeping well,

All the Best,

BillZ

Dear Asyn,

Avast Free anti-virus

Program 2014.9.0.2016

Defs 140322-0

Windows 64 bit

I live in Thailand and I bought the machine with pre-installed software including ESET anti-virus in Thai. I think I have got rid of it all.

Hope you are keeping well,

All the Best,

Download the ESET Uninstaller,and run it in safe mode.You may have remnants leftover from eset.

First, be sure to get rid of all remnants of your prior installed AVs.

Then:

Download avast! Free Antivirus: http://files.avast.com/iavs9x/avast_free_antivirus_setup.exe
Follow instructions: http://www.avast.com/uninstall-utility (Run this tool for all prior installed avast! versions…!!)
Reinstall avast! with the downloaded installer from point 1.
Reboot.

Thanks Marc and Asyn, it worked.

I deleted ESET via safe mode, I had used the uninstaller but not in safe mode.

I still had a problem with avast, but I had tried uninstalling but not properly.

I uninstalled in safe mode and then reinstalled and it is working fine.

Thanks for all your help.

Hope you are keeping well,

All the Best,

BillZ
