If you cannot turn off your antivirus here is a workaround that I found that doesn't involve editing the unpackPkgZip file. Debugging the unzip package function and then stepping through it gives the antivirus enough time to do its job without interfering. Use this command:

debug(utils:::unpackPkgZip) install.packages("packageName")

and then step through the code (by pressing enter many times) when R starts debugging during the installation.

I found this solution here.

If you want to make this change more permanent you can add the debug code into your Rprofile file, see here, but you'll still need to use step through the unzip function each time a package is installed.
