Avast dll crashing Internet Explorer

Avast Free Antivirus / Premium Security
1

Hi,

I’m getting browser crashes in IE10 on Win7 SP1. It will just suddenly happen. The tab will crash with an “Internet Explorer has stopped working” message. It will try fix it, but can’t, and then I have to hit ‘close’ and the tab will refresh itself. Sometimes all the tabs refresh themselves after one of the tabs crashes.

It’s related to an Avast process called aswJsFlt.dll

Whenever a tab crashes, I get the following message in Event Viewer:

Faulting application name: iexplore.exe, version: 10.0.9200.16537, time stamp: 0x512347f7

It’s happening often now. Please advise. Thanks.

I believe that is an avast script shield file. You could investigate by turning off/uninstalling the script shield for a while.

Hi, mag. Thanks. That didn’t work though. I switched off script shield and IE10 crashed again within minutes:

Hi, JuninhoSlo. I’m on the latest version, 8.0.1489.

Just happened again as I opened a tab to visit this forum:

Hard to know what to suggest - I have W7sp1, IE10 and avast free and have no issues.

You could try an avast repair - Control panel, uninstall, repair. I’ve rarely known it solve a problem though.

You could also try completely uninstalling the scriptshield component from avast to see if that solves it.

What other addons or plugins does your IE10 have - you could try disabling them.

Hi, mag. Thanks. Yeah, just some standard addons – flash and Java and whatnot. I’ll try disable them and uninstall script shield, like you said. Yeah, strange problem.

Unless a member of the avast team or someone more knowledgeable chips in that’s about all I can suggest - keep disabling things and see if you can track down the culprit.

(I take it you’ve already tried clearing IE cache?)

I would try uninstalling webrep from IE10 too. Shouldn’t logically be connected, but I do recall a plan for webrep to also interrogate malware info sources - and a scriptshield library may possibly be one of those sources? Don’t know if it was ever carried through though.

As a last resort you could try a complete uninstall/reinstall of avast - with no guarantee that anything will change though.

Hi. Thanks for those suggestions. Yeah, I have cleared the cache. And I’ve had WebRep disabled for ages now. Not a lot really to disable, just flash, PDF helper and the Java plugin. But I will try running IE10 without them for a bit. So, yeah, I suppose I’ll have to uninstall/reinstall Avast when I have a chance, like you say, if just to perhaps rule that out. Thanks for your help, mag.
