My AVG has picked it up every day the last 3 days
According to Dell tech, the vzbb.dll entries can be safely deleted. They refer to/are BHOs with the Verizon toolbar.

verizon is my internet service, however I am not aware of the purpose of this program. I dont think its about my connection.
Apparently it is flagged as a trojan etc by several antivirus programs and spyware programs.
  Luis F. Garcia  
Im not sure if it is good or bad, but some websites say that it is a vundo file, and vundo can be dangerous. But im not really sure if it is.

Surely not essential. Another exploit path I don't need.

Best practices for resolving vzbb issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active vzbb process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the vzbb.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
