I’ve been an happy customer of AVAST free for years now, and after reading an article in my favorite magazine about the latest virus technology, I decided to buy Avast Security Suite 5.0.
Now, I have a top notch computer (i7 920, ATI5870 in CrossfireX, OCZ SSD boot in Raid 0, 4x500GB Raid 10) and i since i’ve installed Avast Security 5.0 and making the latest update, i got BSOD at boot time (irq_less_or_equal).
Since i got a dual boot on my PC (XP/Win7x64), and after trying to boot in safe mode in Win7 w/o success i started my “old” Win XP. It first went well but since it has been a few weeks i’ve booted in, i started the update of Avast. After this update i was asked to reboot which I did and OMG I got BSOD back again when booting in XP. At this point I was a little frustrated because i wasnt able to boot in Win7 safe mode so I really hoped that it will luck with XP. So i booted wiht XP save mode and, lucky me, it ran w/o problems… next step was to uninstall AVAST security suite 5.0 and rebooted back again in normal mode in Windows XP and wonder my XP worked back again…
So I can assume that there is something very wrong with AVAST ? Or perhaps I had some deep incrustrated rootkit ?
Also, since Win7 save wont boot can someone tell me how to fix this ?
Since i got dual boot I booted in XP, located the file “aswNdis2.sys” and renamed it as “aswNdis2.sys.old”.
Before rebooting, I’ve downloaded aswclear5.exe http://www.avast.com/uninstall-utility and then rebooted in Win7 safe mode.
In Win7 safe mode, i deactivated the Avast selfprotection (in settings) in started aswclear5.exe.
Reboot back again in Win7 (normal mode) and everything worked back again except the fact that i didn’t have Avast running.
I’m now gonna try to re-install Avast with the firewall off.
ywdt, please, zip and upload the C:\Windows\Memory.dmp file to this anonymous ftp server: ftp://ftp.asw.cz/incoming
Please, go to folder \windows\minidump and send the newest (recent) .mdmp files for analysis. There is also C:\Windows\Memory.dmp file.
Better if you can compress (zip) them and add some information about the BSOD and the link for this thread.
Manual dump: when the machine is in stalled state, hold down the rightmost CTRL key, and press the SCROLL LOCK key twice. This will cause a machine to ‘blue-screen’ and dump of memory will start.
In notebooks without the right most CTRL key, see http://forum.avast.com/index.php?topic=51847.msg440718#msg440718
I have been having either BSOD or just plain reboots on three computers (XP on the secretary, Win 7 32 on two others) ever since I upgraded to Avast 5 ISS. We ended up just uninstalling it completely on the secretary’s computer and our service tech will probably put Trend Micro (his favorite) on it. I’d rather continue to use Avast (as I have for many years), but can’t take the chance of losing my work, or having more days of downtime trying to debug it. We turned off all of the services, and it still just rebooted her computer. Did a full uninstall of Avast and it’s worked perfectly for a day now.
