avast! Internet Security in combination with OrthWin

[Waterfiets]

Hello,

One of our customers (a dental company) works with a program called OrthWin. It works fine with version 5.0.667, but with version 6 or higher the computer just completely freezes when you start the program. It's already added to exclusions. The program is started from a server.

I'm still trying to figure out if this is an avast-problem or an orthwin-problem.

The guidelines for solving of the problem of using too much CPU has always been the same:

1. Check if the avast tray icon is spinning (while CPU usage is high)
2. If it is, click it (wait for the dialog box to open), and check which file is being scanned (spinning icon means a scan is in progress)
3. Find out which of the providers is scanning the file for each of the Shields.

Please download: http://download.sysinternals.com/Files/ProcessExplorer.zip
Run it as administrator, find "AvastSvc.exe" process (avast! service) and when it'll use high CPU, right-click it and choose "Create dump > Full dump". Then compress the dump file and upload it to ftp://ftp.avast.com/incoming/.

You can also use http://public.avast.com/~vlk/hangrep.exe to generate a manual dump of the application (in this case, avastSvc.exe
