Blue Screen

I use the computer with vista.Suddenly there was the Blue Screen in my computer (STOP: 0x00000050 (0x9f748000, 0x00000000, 0x82621b76, 0x00000000).

Then I used the bluescreenviewV1.0 to get the reason of the Blue Screen .the program shows:“avast’s aswSP.SYS cause this problem.”

How do I finish this problem? thanks.

Is this a regular occurrence ?

If so, you could try install the latest avast beta 6.0.1273, http://forum.avast.com/index.php?topic=83583.0, which has a number of these problems resolved. Or you can wait for the next program update which shouldn’t be too long.
