If you are using Windows try turning off Windows Security real time protection.

Answer 3

But, don't do it permanently, it was just for testing. Because this way you will be exposed to several security threats.
You can set an exception in Windows Security for Rstudio to make it work. You can do it by following the steps given in this link.
