I've come across an issue where Internet explorer will not successfully launch with "Exploit protection" from MB 3.0 premium enabled. When you attempt to launch IE, you receive a whirly mouse pointer for a couple of seconds before IE crashes. You never see any sign of IE visibly launching on the display. I mainly use Firefox for browsing, so this is a minor issue with me, I do not need assistance further diagnosing this, but am posting this information to help improve the product and assist others. I have identified a workaround, which is to disable "Exploit protection" for Internet Explorer (only) - Of course disabling a protection method for one of the applications which it is most important to protect is far from ideal (but in my case acceptable as I only use IE for a few sites that I trust). (The setting is found under Settings => Protection => (Under Exploit Protection) "Manage Protected Applications" => Turn off "Internet Explorer (and add ins)" x64 Relevant information: Malwarebytes 18.104.22.1689 - Premium (with lifetime license) Windows 10 Professional 64 bit. - v 1607 English International (EN-GB), updated to include December 2016 patch Tuesday.

Narrowed that down to all protection methods running except "Exploit protection" - IE runs OK Re-enabled "Exploit protection" - IE Fails to launch. Under "Exploit protection", In "Manage Protected applications" disabled "Internet Explorer (and add ins)" - IE runs OK Re-enabled that setting - IE Fails to launch. Under "Exploit protection", In "Advanced Settings" disabled all protections in all categories. - IE Fails to launch. In those "Advanced Settings", Restored the default protections. - IE Fails to launch. Disabled Kaspersky setting to force its protection extensions into browsers Accessing IE "Manage Add-ons" settings, disabled all extensions - IE Fails to launch. (note: in the above I disabled "Exploit protection" in order to access the "Manage Add-ons" form, then re-enabled it for the test. Re-enabled Kaspersky forcing its protection extensions into browsers Re-enabled IE add ins. Comment: Three changes occurred to system in a relatively short time (Upgrade to MB 3.0, KTS 2017 patch C and the December Windows Updates), I only noticed the issue after all three and so cannot say if the Windows or KTS updates are implicated. I was not running Anti-Exploit before MB 3.0. Additional issue: the "Manage Protected Applications" seems a bit screwy... This morning I had three "Internet Explorer (and add ins)" items in the list, only one of which could be managed. This evening I have only one again (but sometimes activating the switch has no visible effect but does appear to actually change the setting)
