Well I'm going to put this out there and see... Anyone else getting the infamous Internet Explorer (Not Responding) ghostly-white freeze-ups? I'm going to assume for a minute that it's the SafeOnline BHO add-on. Why? Just happened for the first time on this brand new build of a Vista Home Premium 32 system. While IE was ghost-white and hung up with Internet Explorer (Not Responding) ON THE TITLE BAR, I also noticed that the Prevx tab (actually a SafeOnline tab) above the title bar was missing. It's supposed to be there in any IE window. Microsoft basically blames any IE "not responding" error on either corruption in browser cache, cookies, temp files, etc, or one of the many add-ons & toolbars that people typically have. This is not regular and consistent, but I just reloaded this system minimally (new hard drive) and it happened while I had one instance of IE open (3 tabs). Coincidentally, I was writing to Prevx support in one tab when the freeze happened. The other tabs were Yahoo Inbox, and Wilders Forum. I have been a regular user of SafeOnline since it was launched. I have also recently uncovered a stray conflict in Prevx which was acknowledged by support and in this board. All three systems in the household (similar configs) have experienced occasional IE not responding hangs. But this was the first on this new build.

Adobe Flash & Reader; an HP all-in-one printer; Microsoft's own crap including Bing Bar; PREVX 3 with SafeOnline; Java; Norton 360 (my main security program); that's it! Also loaded but not present in IE is Windows Defender. All programs and updates are 100% up-to-date according to Secunia PSI (these are my 4 layers of security and I'm behind a router. I am 99% certain the system is clean of any malware. Like I said, my biggest hint is the Prevx (SafeOnline) tab which sits atop the IE title bar. When IE stopped responding, the Prevx tab was not in view. I could spend a week disabling each and every add-on and toolbar but I'm not about to do that. Besides, this has happened once, and I'm also pretty sure it's not corrupted temp files, etc. I'm looking for an indication from PrevxHelp on what that missing Prevx SafeOnline tab might reveal, and looking to see if others who are using Prevx 3 / SafeOnline also experience Internet Explorer (not responding). I have used the Norton360 / Prevx / Windows Defender security combo since SafeOnline was created on all my systems. My main system was the one which flagged a recent Prevx3 bug, and it experienced a number of IE (not responding errors) over the last year or two. I am of course upset that this IE freeze happened on this new build, while I was well into another Prevx Support email - lost about 200 words and will have to start over on that one too! I typed this out in Notepad (just to be cautious). I also wish there was some kind of mini-dump log file that would identify the cause of these IE hang ups.
