We have an application written in 2.6a which uses a fairly extensive set of tables. A number of our customers are complaining that the system's response time has become very slow (30 seconds and more between screen changes, for example).

We have found that in many cases, our users have installed Norton antivirus and that enabling automatic checking of files as they are opened is contributing to, or even causing, the problem. We can't just tell the users to turn off virus checking: they need it, and there may be corporate mandates to keep it on.

We have also found that in some cases, turning off auto-checking addresses the issue, where in other cases, only un-installing the virus checker helps.

Does anyone have any experience with virus checkers, their interactions with Fox 2.6 apps, dependencies on O/S, settings on the virus checkers that will help fix problems, etc.?

This is an increasingly severe problem for us, so any suggestions will be appreciated.


TIA
Bruce
