Same issue.
1. Latest version 17.4.2294 Avast Pro
2. No
3. WinXP pro Sp3, 32bit
4. Performed Avast Clear and reinstall the off-line version. But PC also freezes (keeps 95 ~ 100% CPU loading )
So disappointed Avast software quality control in 2017.
Many big mistakes from Avast......
Last time was Blue Screen Fault in Win7, 32bit.............
What is Avast doing now
?
Please fix it quickly , or re-post the download link of previous Avast Pro / IS off-line version (all in yr 2016) to us.
