remote desktop reboot when avast is turned on

Avast Free Antivirus / Premium Security
1

I have been using Avast for many years, never had a problem. I am very satisfied by its protection overall.

But now I am facing an awkward problem which lead me to write to the forum because I have tried many things, and run out of options. Sometimes when I remote desktop my pc with avast turned on, it reboots with a bugcheck (1C if I remember well). The OS is Windows XP SP3. The same pc with the same configuration has been using avast for years.

The story began last month when I noticed that sometimes my pc reboots when I try to remote control it via MS remote desktop. I began troubleshooting, tried many things (update drivers, check hardware, memory with memtest etc). Then, I read in the internet that there is a slight chance that it’s av-related, so after a lot of troubleshooting I decided to turn avast off. And yep, the pc stopped rebooting …

It’s very strange, because the pc is only used for casual surfing etc. I have not installed anything new software or hardware, just updated avast. Memtest shows no errors. Hardware is old (bought around 2004, its a intel p4@2.4 with 2GiB RAM on an asus P4PE motherboard), nothing has been added or removed for several months. The system is stable, apart from that strange bugcheck when someone remote controls it.

Any idea how to proceed? I have verified that it does not reboot if avast is turned off. But I want to use Avast. Just have no idea how to proceed.

Stuff I have tried:

  1. update video card, mobo drivers (although most of them have not changed since 2008-9)
  2. reboot … ofc
  3. remote desktop from different pcs (linux, windows 7, windows xp)
  4. disable other drivers and other programs may could cause conflict.

Any recent minidumps in C:\Windows\Minidump folder - that might correspond to the reboots?

Here is the error:

“The computer has rebooted from a bugcheck. The bugcheck was: 0x1000008e (0xc0000005, 0xbf952937, 0xb6001c00, 0x00000000). A dump was saved in: C:\WINDOWS\Minidump\Mini011312-04.dmp”

It may not be avast fault per see, maybe a strange combination of hardware fault, or software conflict. Don’t know…

But with avast off, it seems to be working okay.

Same recent dumps.

Also I have such errors:

The computer has rebooted from a bugcheck. The bugcheck was: 0x10000050 (0xbbf6fff0, 0x00000000, 0xbf8a80a4, 0x00000000). A dump was saved in: C:\WINDOWS\Minidump\Mini121911-01.dmp.

Maybe two different things?

Everything seems to have crashed somewhere in GDI, but I’m no expert in this to say what might be the real cause.
Let’s see if PK finds a while to come here…

K, thanks for your fast response.

Could you tell me what program you’d use to analyse minidumps?
