I have BD Pro and I had it on auto update but I was getting this error in event viewer: Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7034 Date: 1/8/2006 Time: 10:18:43 AM User: N/A Computer: MELE Description: The BitDefender Virus Shield service terminated unexpectedly. It has done this 5 time(s). For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. I got this error repeatedly since I got BD Pro instead of BD free where I manually updated. I put BD on manual update and I don't get the error. What was causing it to stop 5 times? Trying to update and being unsuccessful? After each error is this in event viewer: Event Type: Information Event Source: Service Control Manager Event Category: None Event ID: 7035 Date: 1/8/2006 Time: 9:18:39 AM User: NT AUTHORITY\SYSTEM Computer: MELE Description: The BitDefender Scan Server service was successfully sent a stop control. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. Then more events related to auto updating BD. So, it looks like the unexpected stopping of BD is related to inability to update and repeated tries? Those above entries were in System. In Applications at the same time each time BD would unexpectedly quit and get the error and then would go ahead and update, I see 241 events in Applications! 241! These are over and over and over, over making the log extremely long for just one day. They all are the same event...241 times and all concern Bit Defender: Event Type: Information Event Source: HHCTRL Event Category: None Event ID: 1904 Date: 1/8/2006 Time: 2:59:22 PM User: N/A Computer: MELE Description: The description for Event ID ( 1904 ) in Source ( HHCTRL ) cannot be found.

The following information is part of the event: http://www.bitdefender.us/, http://go.microsoft.com/fwlink?LinkID=45840. Is this normal if you use auto updating with Bit Defender?
