Some antiviruses might find our software suspicious. This is usually happening on the first days after an update because some antiviruses build their databases using the number of installs of specific software. Let’s say our software is installed on less than 20 computers with a specific antivirus. In this case, this antivirus can mark our software as suspicious. It will be marked back as trusted when it will be installed on more computers. So don’t worry, your PC is safe!
