A few days ago, after I clicked to open Firefox on my computer, my computer abruptly rebooted without notification or warning. I think it was caused by aswMon2.sys
I tried to attach the minidump, but it said that I can’t upload that type of file.
You can zip the minidump and send to vlk (at) avast (dot) com
Which is your avast version?
My avast! version is 4.8.1351 on Windows XP SP3 32-bit.
