Longs start of .NET applications from network drive

AndrejK

Hello,

We are having problems with Sophos On-Access scanner. When enabled (always and default for every workstation in company) it can take up to 60-120 seconds before a .NET application located on network drive will start. It includes a single executable and around 10MB of DLL libraries which are located in same folder. If I disable On-Access scanning it opens instantly.

If I check the Task Manager I can see that Savservice.exe is peaking at around 20-40% which tells me that DLL files are beeing scanned. And this is taking way too long.

I tried to exclude the folders like so:

\\SERVER\SHARE\FOLDER\ and

X:\FOLDER\

or any other possible exclusion solution but none helped. When user closes application and starts it again from same network path it will open almost instantly. Until next reboot that is.

What can I do? How to correctly exlude those folder from beeing scanned or how to setup the Endpoint so the DLL files are not scanned everytime?

We are using Windows 7 Pro 64bit OS, Novell Netware file server and latest up-to-date version of Sophos Endpoint Security (9.7).

Thank you for your support.

    How to know which file he is currecty scanning?

    I've tried many other exclusion option and none worked. Only exclude remote files works but I can't just exclude all files on network. For now I want to exclude only few paths where we have the .NET applications with many DLL files.

    I tried another thing. On fresh reboot of computer I've tried to copy the folder with .NET app onto local hard drive. It took almost 3 minutes to copy 11MB of files. He is stopping on every DLL file for at least 10 seconds. The average speed of transfer was 110bytes. If I delete copied files on my hard drive and copy the same folder again it will only take 1-2 seconds.

    That is why it also takes so long to start application.

    What else can I do?

    Thank you.
