I have VFP 8 application that has been working for more than 20 years especially with respect to this issue.

Couple days ago, I find out that I have a tracking malware that I needed to get rid of. So I downloaded both Norton 360 and Spy Hunter 5 to get rid of it.

After I ran the Scan then all of a sudden VFP no longer recognizes a Mapped Drive!!
For example If I share a Directory called c:\Drive_F for "everyone Read/Write" and then use the Tools menu and Map it as F: drive. The following happens;

? FILE('F:\test.txt') produces .F. while
? FILE('c:\Drive_F\test.txt') produces .T.

I have tried deleting the folder and remapping it. Or
redoing the sharing, Or
Uninstalling both Norton and Spy Hunter, ...

It seems like the Anti-Virus has changed something in the Environment that makes VT no longer see a mapped drive. Also any application that runs from within VFP no longer see the mapped drive. I could also be legacy applications have this issue.

Anyway, I need to fix it as soon as possible, and any help would be greatly appreciated.
Thanks.
