The easiest and fastest way in which you can remotely control another computer is by using TeamViewer. The software is quite handy for both personal and business purpose and can help you smartly manage different situations without wasting your time.
But, since it establishes the on-distance connection through the Internet, TeamViewer might be blocked by certain antivirus programs – in that respect, the security solutions might see the app as a possible security breach so it will block its access and functionality just as a precaution measure.
Well, if that happens and if you cannot use TeamViewer because of your antivirus software, don’t worry; you can re-enable the program easily by setting up an exception rule within Firewall. Below we will see how to perform this process for the most popular antivirus programs that are currently used on the Windows 10 platform.
