It is designed to repair installations not destroy them so I have no idea why, in your case, you would be seeing that. Unless you are using products not covered by MVT or a non-compatible system.
I suggest you contact Technical Support Chat for clarification. (Useful Links above).
Good idea. The only problem is that it seems we need to use the Virtual Technician first, before we can get through to Technical Support Chat. Now that I have experienced the harmful effects first-hand, I most certainly will not use Virtual Technician again. I am posting the problem here in hopes of sparing others the same hard-learned lesson.
In my case, the damage was eventually repaired by a McAfee Support Technician. But it took almost an hour-long remote control session, and he had to delete all the McAfee entries in my registry to get Total Protection re-installed and working properly. You're right that there is a compatibility problem, and it's entirely within McAfee's own product lines.
Well I still doubt that MVT actually broke something...more likely it was broken already and MVT tipped it over the edge so to speak.
Without specifics it's difficult to tell you what might have happened but I assure you I haven't ever heard of MVT actually breaking something.
