Sorry to hear of your problems john but they are well timed from my point of view.
My Bullguard license is about to expire and I was considering going back to AVG which I had used for years up till there were issues with version 9.
Think I'll continue to give it a miss in the light of your comments.
Have already swapped Bullguard for MSE + Zone Alarm on my laptop and both seem to be quite happy working together. If I recall AVG were always blaming ZoneAlarm for problems with AVG 9.
Have not yet decided whether to stick with MSE on the desktop or try Avira or Avast.
