avast Service (32 bit) using more than 50% of the CPU
« on: December 27, 2015, 11:01:31 PM »
Hi,
Since a few weeks I have that problem happening when surfing on internet. Every time I open a new page, avast Service (32 bit) starts using up to more than 50% of the CPU, making the computer run very slowly. The problem occurs with Chrome, Firefox and Edge. I'm using Avast Free for years, never had that issue before. Current version I have is 11.1.2245
Would you have any clue?
Thanks!
Cheers

- OS..? (32/64 Bit..? - which SP/Build..?)
- Other security related software installed..?
- Which AV(s) did you use before Avast..?

- Processor 3.20 GHz, 8,00GB RAM, Windows 10 home 64-bit
- No other security software
- None. Using Avast for years and this PC is pretty recent so I never installed any other AV on it

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