Avast causes blue screen

Hi, my desktop pc is new and i’m frequently having the blue screen DRIVER_IRQL_NOT_LESS_OR_EQUAL. I found in google this is caused by avast but was fixed 1 year ago, why is this happening ? I have avast internet security (last updated) , and here you can see the avast proces in the blue screen info

aswndisflt.sys thats from avast

New systems often come with a preinstalled anti-virus.
Did yours too?
If so, did you removed it before installing avast?

It had avg free, yes, i removed it before installing avast. Anyway i will try reinstalling avast to see if that solves the deal.

There are removal tools for most AV’s here http://www.avast.com/en-gb/faq.php?article=AVKB11 to remove remnants before installing Avast.

Unusual that AVG came preinstalled on a new system, I’ve not heard of that before ??? usually it’s Norton, McAfee or TrendMicro.

I did that and never got the blue screen again,thanks !
Probably the guy who installed windows installed avg too. Itsn’t a pre assembled pc.

Thanks for the help !

Your welcome :slight_smile:
