Just wanted to post this as it would have helped me if present on this page. Had same problems with avgidseh.sys failing on Windows 7. Booted in using an ubuntu usb and renamed all the windows/system32/drivers/avg*.sys files. This didnt fix the problem, although the failure also moved onto classpnp.sys as per above. Tried various other routed (eg mode to IDE etc) as AVG says it cant be their problem but to no avail. I then looked again and saw the problem had moved back to avgidseh.sys. This time I booted in and deleted the avg*.sys drivers, removed an AVG dir under drivers too and also renamed the avg folder under Program Files then restarted. This appears to have solved the problem for me - AVG is it really not you? Anyway hope that helps someone...
Same problem with avgidseh.sys in safe mode. Thing is it was a Server 2008 standard. Connecting the disk to another PC I managed to get rid of all the files mentioned using Linux LiveCD. Still it wouldn't go into safe mode this time stopping on loading avgrkx64.sys even though it was physically deleted. However, it started in normal mode with lots of pain. Used AVG removal tool and then it came back to live.
I installed AVG for the first time on my laptop today in order to run a scan. The scan found five threats and asked to reboot and I've been stuck in reboot loop eversince. I have tried to rename avg's sys files to no avail. (the only change being that I get a bsod/reboot when windows safe mode boot gets to CLASSPNP.SYS instead of the previous avg*.sys). I have now tried to follow the steps described above (changing the hard drive settings in BIOS ) nd have also attempted to remove the avg folders and sys files altogether. Still stuck at CLASSPNP.sys I will probably have to do a clean install in the morning. I would be surprised if the issue were not related to AVG as this great amount of trouble seems to have been triggered by a simple first scan under a fresh install of AVG. I am running on windows 7 64bits
3 more occurrences of the same problem. One ended up with re-installation as I couldn't even get to Safe Mode and removing all the avg.... files from Drivers folder didn't work very well as it was then hanging on avgrkx64.sys. In normal mode ( Windows 7 ) the system was hanging on Welcome screen. Other 2 after running AVG removal tool in Safe Mode all went to normal. Sorry but I just have no time playing with memory dumps.
Would it be possible for AVG to to get your removal tool do it's job on external drives in case you can't get into safe mode?
Cannot it be made to do it on an external drive. Surely you can delete files and edit the registry on an external drive although the registry bit is a bit fiddly as you need to do it from the same OS that's installed on the external drive. Anyway it would be a very effective lifesaver when you can't get into the system. I'll try getting the dumps next time I get into this sort of issue as we have many clients running AVG in different environments and by the look of it it's just a matter of time we get another one to fix. Just hope it won't be a server again.
