Hi, I have sometimes caused by a blue screen as you had read from minudump of my pc. Can anyone help me?

I used a program (MemTest) and says it is ok. In the windows error reporting (minidump) there is written:

Bug Check String: IRQL_NOT_LESS_OR_EQUAL
Caused By Driver: aswTdi.SYS
Caused By Address: aswTdi.SYS + 2ca1
File Description: avast! TDI Filter Driver
Product Name: avast! Antivirus System

who can I contact?
thanks

What version of avast are you using and what is the build number, e.g. 6.0.1203 ?

What other security software do you have installed ?
Have (or did) you another Anti-Virus installed in this system, if so what was it and how did you get rid of it ?

There was a bug in aswTdi.sys in 1203 - and it was fixed in beta 1279.

Thanks for the information pk.

The current beta is quite stable, certainly on my system. So if you want to try it, see this topic, http://forum.avast.com/index.php?topic=83583.0 for information and download links. Or you can wait for the official program update release, which hopefully shouldn’t be too long.
