With McAfee, you can’t add folders as exceptions, so you need to go through the tedious process of adding each file from the WeMod folders as exceptions.
C:\Users\%username%\AppData\Local\WeMod
and
C:\Users\%username%\AppData\Roaming\WeMod
Otherwise, the only other advice we can give is to switch antivirus providers (eg. Malwarebytes, Norton, etc.)…
…or turn off McAfee when using WeMod, which we highly advise against as this can leave you vulnerable to malware.
