Old Powerpoint Files (PPT) are opening slow over vpn

Dear Experts,

I have a user which started to have an issue with opening ppt files this week over vpn.
The strange thing is it's only happening with ppt files, pptx are opening fine.
If I copy the ppt file from the Shared drive to the desktop it takes 3-4 Seconds to copy and around 10 seconds to open.
If I open the same ppt file directly from a network share it takes around 3-4 Minutes to open or Powerpoint is even crashing.
The same files are opening fast when on the Office network.
I'm running out of ideas what could be the issue.
I tried the following until now:

- repair office
- Adjust MTU of the Wifi adapter
- start Powerpoint in safe mode
- disable all Add-ins
- Add network share in the trust center to trusted locations (including subfolders)

It's still the same after all this.

the following is used:
- Windows 7 64 Bit
- Office 2013
- Cisco Anyconnect

Best Regards and many thanks in advance for any input,

Patrick

Hi Jamie,

It seems that the Reason is AV Scanner. moved ppt files to the Exeption and it's working fine. But now we are trying to get this to work faster without having to exclude ppt from the on access scans.

But no final and scure solution yet.

Many thanks for your input :-).

Have a nice day,

P
Great - so my comment 42217195 above regarding AV software is the answer. If you agree, could you award the points and close this question? Thanks.
