Avast Causing Crash in IE11

[matthew_001]

Hey Gang,

   It appears that Avast (Free Version) is causing IE 11 to crash when attempting to sign into web sites (like Amazon).  High level (without source) this appears to be caused by passing a logging string that points to memory that is invalid, just a guess though.  Error Message with details:

The thread 0xf44 has exited with code 0 (0x0).
Unhandled exception at 0x747D2B8A (msvcr110.dll) in iexplore.exe: 0xC0000005: Access violation reading location 0x6946206D.

Here is the call stack that comes from a debugging session if IE when this crash occurs:

>   msvcr110.dll!__woutput_l()   Unknown
    msvcr110.dll!__vsnwprintf_l()   Unknown
    msvcr110.dll!__vsnwprintf()   Unknown
    aswWebRepIE.dll!60d4192a()   Unknown
    [Frames below may be incorrect and/or missing, no symbols loaded for aswWebRepIE.dll]   

I can provide a crash dump for any interested devs.

~Thanks,

Disable the Avast Online Security (AOS) plugin, should fix it. The web shield does all the malicious blocking.

Are you by any chance using Enhanced Protected Mode, if you are then AOS is not compatible with it.

Thanks I already disabled the Avast plugin.  That fixed the issue, but I was hoping to help get the problem fixed so I can continue to recommend Avast to friends and family.
