BSOD referencing "aswSP.sys"

Avast Free Antivirus / Premium Security
1

Hi! Um…how should I start…I just uninstalled the Norton Internet Security trial on my computer through “program and features” and I also ran the Norton Removal Tool. Then I downloaded Avast 5 free and installed it successfully. The installer did not ask me to reboot the computer. I registered Avast 5 online. Afterward, I restarted my computer and upon startup I got a BSOD about “aswSP.sys”. The computer restarted immediately after the BSOD. I couldn’t catch the bugcheck. I got a minidump but I don’t know where to upload it. This occurred on Windows Vista SP2 x86.

edit:

I guess I forgot to mention that the error does not show up again after the computer automatically reboots. It only showed up once. I can’t seem to deciphered the minidump using the windows debugger.

I’m not sure if this code is relevant: 0x00000050 (0x9ccd1000, 0x00000000, 0x8eb757ff, 0x00000000)

can you boot up at all? if you cannot, tap f8 on startup and turn off automatic reboot so you can see the error and get it to us

I had BSDs on two two machines with Internet Security 5 and received a new driver from avast to replace aswSP.sys in the system32 driver folder. The new driver seems to have fixed the BSD problems. On one machine, I got a BSD (page fault) as soon as I rebooted from the installation which forced me into the Safe Mode. In the Safe Mode, avast isn’t run so I was easily able to replace the aswSP.sys driver. The instructions I received from avast had me disable the self-protection module but I found this step totally unnecessary. They sent me both a 32-bit Windows and a 64-bit Windows aswSP.exe file replacement. On the second computer, Internet Security 5 installed without a problem but over the next two days I experienced random BSDs that quickly threw me into a restart. I haven’t seen BSDs since Windows 95 so suspecting the same avast problem, I replaced the aswSP driver on my second machine and I have not had any BSDs for the last two days.

It would be nice if Avast made this file available in their updates and let us know about it.

I’m sticking with 4.8 until an official word has been given.

I am about to do the same. In addition to the BSD problems, I can’t get a critical DOS program to execute and uninstalling Version 5 solved that problem also. No problems with 4.8 so I guess I will move both machines back to 4.8 The real question is do I ask for my money back on Version 5 since they have a 60 money back guarantee?
