Unfortunately, no. This notification is not supposed to be customizable. This is a warning message that tells the user that their computer might be accessed by someone not being authorized to.
The fact that this message only shows for the free license means that it was the free license/version that was often abused in the past. We had to implement this message to restrict the ability to use the free license for malicious purposes out-of-the-box.
AVG/Avast keep detecting the program with each new release. We have no idea why this company is ruining the work of their users/customers by blocking benign/legitimate software on their users' computers. This is weird.
Yes, Pauline, I have AV software installed on all of my computers but it is not interfering with RU in any way. This is clearly a host software issue. Both host computers are reporting the same fatal error.
Could you provide the antivirus software name, please. Thanks.
