[IE] DEP Errors

Although DEP is turned off IE 11 crashes due to: Windows Data Execution Prevention detected an add-on trying to use system memory incorrectly. This can be caused by a malfunction or a malicious add-on. This does not occur on every site just 2 or 3. The last two errors from Event Viewer are as follows: Faulting application name: IEXPLORE.EXE, version: 11.0.9600.17126, time stamp: 0x53882e30 Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000 Exception code: 0xc0000005 Fault offset: 0x1e261c10 Faulting process id: 0x508 Faulting application start time: 0x01cf8629ba971b65 Faulting application path: C:\Program Files (x86)\Internet Explorer\IEXPLORE.EXE Faulting module path: unknown Report Id: 142bdbe1-f21d-11e3-8c5e-446d57f87030 Faulting application name: IEXPLORE.EXE, version: 11.0.9600.17126, time stamp: 0x53882e30 Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000 Exception code: 0xc0000005 Fault offset: 0x3002b358 Faulting process id: 0x1920 Faulting application start time: 0x01cf86272ff526f3 Faulting application path: C:\Program Files (x86)\Internet Explorer\IEXPLORE.EXE Faulting module path: unknown Report Id: f098a9f5-f21c-11e3-8c5e-446d57f87030 All updates are current and the system has been thoroughly scanned for all types of malware.
