Add me to the BSOD folks.
Happy Sunday to me.
Just an FYI because I'm seeing a few responses in the forums below as if this is a rare problem or some inferring the BSOD reporters are only whining or running conflicting software or that the user is doing something to blame themselves. I suspect that may not be the case in this instance. Me: Win 7 x64, standard HP general public mass-produced 2-year-old box with nothing fancy installed and all the fat removed from initial setup, 6GB memory on wired internet broadband, no problems and always running wonderful over the lifetime of this box with Avast from day-one.
Until 6am-ish this morning at upgrade/reboot to Avast .1489 anyway. Four hours later I was still trying to get the use of my pc back. Something fought me even trying to uninstall .1489. After upgrade/reboot whatever changed Windows just struggled against every keystroke, to BSOD over and over, took down internet connection, IE software wouldn't open from Taskbar button, network/other pc's fine still, Chrome opens but no internet, refused to let me use old system restore points (from safe mode). Diagnostics run otherwise, no issues anywhere. Eventually it let me uninstall in safemode. Anywho running very late now but at least pc back no time to grab whatever file and drop wish I could give it the day but I need to be far far up the road by now sigh: will revert to .1483 (was where I was before 6am) and as it doesn't seem to be a unique-to-me issue then it will likely be worked out over the next week or so and so I will try updating program again in a few days.
Interesting though was that I haven't seen a BSOD since Windows 98 SE -- ahhh, my old friend.
But where is the *official* site I can download the old .1483 version from safely? Very careful where I go these days, and especially in the next few minutes.
