So, it is better to disable the security program temporarily and see if the problem is gone. Before disabling the virus guard, however, it is important to read the instructions provided by the developer.
If disabling works, you should permanently remove the respective tool and install a new one. If not, you should contact the developer and ask for a solution.
Note: After disabling the virus guard, you should be very careful when surfing the web and doing other tasks. For instance, preventing USB drives on the computer is better after disabling the virus guard.
