Would you recommend upgrading the VirusBarrier Scanner to the paid version rather than the free one that was on my MacBook Pro

The idea that a third party, with no special knowledge of the inner workings of MacOS, can somehow find a simple way to protect your computer -- that is not already being done by MacOS itself -- suggests that the MacOS developers are somehow "holding out on you". That is absurd.

You should remove any and all (other than Apple built-in) virus scanners, speeder uppers, optimizers, cleaners, App deleters or VPN packages you installed yourself, or anything of that ilk.

Third-party file Sync-ers such as DropBox, BackBlaze, OneDrive, or GoogleDrive can ruin performance, but are not inherently dangerous.

I would recommend uninstalling the app and not use any anti-virus apps. the only thing those apps are good for is separating your money from your pocket, and causing major issues within macOS. there are no viruses that affect your Mac. as of Big Sur, macOS resides in a sealed volume that is unchangeable by anyone save apple.

if you are concerned with keeping your Mac safe, I would recommend that you read Effective defenses against malware and other threats - Apple Community. it's a long article but worth your time to read every word.

+1 on my amphibian amigo's excellent advice!

The only reason to leave that dreckware on your computer is if you want it to run like it's 1992 again.

Let your Mac be a Mac.

😉 I awoke thinking I needed to brush up my alteration this morning!

I find your alliterations refreshing and joyful!

if you don't get back to it 'before the ink dries', your second comment seems more like a Spoonerism.
