My Time Machine has stopped backing up because "An error occurred while starting the backup. Anti-virus software may be preventing Time Machine from writing to the backup." My back up disk is no longer on my desktop and nothing is listed in Disk Utility. I have NetBarrier software that I just updated. What is the problem??

First, there is no reason to ever install or run any 3rd party "cleaning", "optimizing", "speed-up", anti-virus, VPN or security apps on your Mac. This user tip describes what you need to know and do in order to protect your Mac: Effective defenses against malware and other threats - Apple Community.
There are no known viruses, i.e. self propagating, for Macs. There are, however, adware and malware which require the user to install although unwittingly most of the time thru sneaky links, etc.
Anti Virus developers try to group all types as viruses into their ad campaigns of fear. They do a poor job of the detecting and isolating the adware and malware. Since there are no viruses these apps use up a lot of system resources searching for what is non-existent and adversely affect system and app performance.
There is one app, Malwarebytes, which was developed by a long time contributor to these forums and a highly respected member of the computer security community, that is desshoigned solely to seek out adware and known malware and remove it. The free version is more than adequate for most users.
I suggest you do what leroy recommended and remove NetBarrier according to the developer's instructions.

Try disabling your third party AV and test.
Third party AntiVirus is not recommended— it typically does nothing but add issues to the macOS and competes directly with Apples own built in security:

Have you try another Extern Harddrive for your Time-Machine back-up?
Timemachine-Capsule,or and extern Harddrive?
If A/V is an issue on this,matter, uinstall the A/V when your using your Time Machine!
I have removed Net Barrier and all the other apps in the Intego bundle, as well as MacCleanse. My external drive which has worked well for the Time Machine no longer appears on the desktop. Has it been corrupted somehow through this process? It is a 5T easy store hard drive from WD and I would hate to lose it. Any hope of being able to use it again?
Tried to run First Aid on the easy store drive. Got this response:

Do I need to erase the hard drive (and lose all my previous backups) to use this drive again? Will that work?
Yes I would TRY erasing and then use it for ™ backup. However there MAY be problem with the disk. I would try reusing the WD disk but also get another disk and backup to that disk too just in case.
When you have one ™ disk and connect another disk and select the second disk ™ will ask you if you want to use the new disk all the time or use both disks. If you select both disks ™ will alternate which disk ™ uses.
My Time Machine has stopped backing up.
