1. Update your Windows Defender definitions (you will use this as a back up later when Avast is uninstalled), but keep it off for now.
2. Do a complete Avast Uninstall as stated earlier using the Avast Uninstaller Tool and Rejzor's Tool In
SAFE MODE, then
reboot.
3. Turn
ON Windows Defender (WD) as well as the machine's internal firewall (FW).
4. If you have MBAM (Malwarebytes-Antimalware) Premium, which I hope you do, make sure this is also functioning properly for an extra layer of protection (it works differently than an AV, but is compatible with AV's). If you like, you can get the free version for now since we will need the log from that as part of the diagnostics for the malware specialists. Most of us here use MBAM anyway.
5. I need you to run scans and attach logs to make sure we are not dealing with malware causing your problems. Please refer to the directions listed on this link:
https://forum.avast.com/index.php?topic=53253.0 and follow the directions for posting the basic logs for:
- MBAM
- Farbar Recovery Scan
- aswMBE.exe
Please ATTACH them to your next post so that can be reviewed for malware. Thank you.
