Update 3449 and Lenovo Access Connections

I believe update 3449 (20080917) has caused a conflict with Lenovo Access Connections 5.02 on Windows Vista Ultimate 64-bit. Upon boot, ekrn chews up at least 50% of the CPU and refuses to let Access Connections load. Disabling NOD32 resolves the problem, but obviously this is a poor solution. Any advice?

 

I had a similar issue with Nod32 2.7 and Access Connections because of a logfile that is created/changed by Windows when Access connections is started or a profile is applied. I had to make a change in Windows registry to disable the logging or exclude realtime scanning of that file to solve the problem. Using nod32 2.7 it's easier to find out since i could see what file that is being scanned. Using nod32 3.0 i don't think you can actually see what file is being scanned. I'm pretty sure the .log file is located under the Windows directory though.
The logfile is not created by AC. It's created by Windows and AC is probably using the Windows API to make some system calls which is the reason why Windows create this logfile.

Not sure if this is the same problem, but you could try to exclude the scanning of all *.log files under the Windows directoyr to see if there is any change. If that solve the problem i'm sure you have the same problem.

 

I grabbed a copy of Sysinternals' Process Monitor and checked out what was causing the fight. Turns out it was a logfile in C:\Users\Public\Documents called AccConAdvanced.html

It looks like a fairly bog standard logfile, but for some reason NOD32 just decided there was something dodgy about it. I added it to my exclusions list for realtime scanning and all is well. It would still be nice to have a more definitive solution but such is life...
