Last update: Wed, 2020-10-14 13:01

Symptoms

You have an antivirus or a different security solution in place and you want to install Acronis True Image 2021.

OR

After Acronis True Image 2021 is installed on a machine with a different security solution in place, the machine displays significant performance degradation, such as programs not running or running slowly, unexpected reboots, slow booting, etc

Cause

Two or more antivirus solutions are active on the same machine.

If more than one such program is running, there are a number of ways in which they can interfere with each other:

  • Antivirus and antispyware programs usually integrate deep in the system to be able to detect threats even on kernel level; as such they will attempt to install monitors in the same part of system kernel, resulting in conflicts
  • Performing the antivirus scan consumes a considerable amount of system resources, running two scans at the same time is prone to completely overload the system.
  • If a threat is detected, each antivirus will attempt to disarm it in its own way, triggering a collision between the two programs. This can result in either false alarms or worst case, system overload by simultaneous efforts from both programs.

Solution

Acronis True Image 2021 integrates with Windows Security Center to monitor the status of Real-time protection, the relevance of Protection updates, and product license status. If a different antivirus is set in Windows Security Center as Virus & Threat protection then the real-time protection module of Acronis True Image 2021 will be deactivated automatically. That ensures that we will not initiate any conflict between two simultaneously running antivirus solutions. To eliminate any possibility of that conflict from the other antivirus part, we recommend that you leave only Acronis True Image 2021 and uninstall the third-party antivirus.

In case the other antivirus solution is not detected by Windows Security Center, then Acronis True Image and the other antivirus will conflict over resources. In this case, we recommend to deactivate either Acronis True Image 2021 real-time protection module or deactivate/uninstall the other antivirus solution. 

On Windows 7, Windows Security Center may incorrectly report the information about third-party antivirus software. If you use Windows 7, please manually deactivate real-time protection either in Acronis True Image or in the other security solution, to avoid conflicts.

To deactivate antimalware protection in Acronis True Image 2021, go to Protection section, and click Turn off protection, then select for how long the protection should be disabled:

More information

On Windows 8 and newer, web filtering can be used independently of installed third-party anti-malware solutions.
