32-bit versions of Internet Explorer were crashing after Intrusion Prevention System (IPS) 20150220.001 definition package was applied to their Norton Products. We have released a fix for this issue through our LiveUpdate servers. See the Security Response Blog Article for more information.
Running NIS on Windows 7 Pro 64-bit with IE11 (latest updated). Sometime this evening, IE11 started crashing. In fact, it crashed an already-open browsing session, and now trying to start it up just instantly causes a "Internet Explorer Has Stopped Working" error.
Tried resetting IE11 settings to default. No change. Tried running IE11 in no-addons mode. No change. The error is shown as the following:

Now, IPSEng32.dll is a Norton file. So I uninstalled NIS. Bingo - IE11 started working like normal. Re-downloaded and re-installed NIS. At the outset (said last updated 20 hours ago) IE11 worked fine. Then it auto-updated and applied a patch... and instantly IE11 stopped working again. Ergo, something Norton did is breaking my IE11. Doesn't seem to have affected another computer I have running IE10.
EDIT: The other IE10 PC had been asleep and hadn't updated NIS yet. It is also now crashing in exactly the same manner as this one... and since that PC is almost entirely unrelated to this one in terms of software being used, this is going to be a bigger problem than just me.
