Antivirus Scan


Acronis True Image 2021 is installed on Windows 8.1 x64.

When you try to run an antivirus scan of the system, scan freezes and never finishes:


This issue is caused by a bug in Windows 8.1 thread scheduler.


You disabled Antivirus and antimalware protection via Pause protection -> Turn off protection.

Despite disabled protection, scheduled antivirus scan continues to run.

In Cyber Protection agent logs C:\ProgramData\Acronis\Agent\var\log\atp-agent you find the following message:

[error] [ScheduleServiceProxy] : UnscheduleTask()[...] No tasks for cmd


Issue in the product.


A third-party security solution detected a PUP(potentially unwanted program) on a machine protected by Acronis Cyber Protect. Acronis Cyber Protect did not detect this PUP and did not generate any alert about it. Why?


Some anti-malware tools detect Adware or PUP`s (Potential Unwanted Programs) in different ways according to internal Cyber Security vendor policies.
