Usually, after installing a security software, there may appear a slight slowdown of the system, which to a certain degree is normal.
If you notice a significant slowdown, this issue can appear for the following reasons:
-
CompuClever Antivirus Plus is not the only security program installed on the system.
Though CompuClever Antivirus Plus searches and removes the security programs found during the installation, it is recommended to remove any other antivirus program you may use before installing CompuClever Antivirus Plus. For more information, please refer to “How do I remove other security solutions?”.
-
The Minimum System Requirements for running CompuClever Antivirus Plus are not met.
If your machine does not meet the Minimum System Requirements, the computer will become sluggish, especially when multiple applications are running at the same time.
-
There are too many invalid registry keys left in your Windows Registry.
Cleaning the Windows Registry can improve the performance of your system. Click the Optimize button on the CompuClever Antivirus Plus interface to visit our webpage with Tune-up tools.

-
You have installed applications that you do not use.
