Removing the antivirus isn’t the best solution, but if it helps, you might want to try switching to a different antivirus tool that is known for fixing such errors.
Perhaps, your current antivirus software wasn’t able to stop the virus from entering your device, or it simply malfunctioned and it’s giving you the error.
Therefore, you need a new antivirus that has a Home Network scanner which keeps an eye on all your home network, thus allowing you to track all possible attacks on every computer in the network.
What you also need from your antivirus is an advanced machine learning AI feature that continuously scans for signatures and blocks them the same second they look suspicious.
