Ryck, I wonder if your persistent Prosoft cookie is actually from Prosoft Engineering or perhaps it is a malware cookie masquerading as a Prosoft cookie?
Interesting thought. The next time it appears I'll try to get a bit of detail.
The cookie appeared this morning, as soon as the computer booted, and this is how "Cookie" described it:
Website: .prosofteng.com
Name:
_cfluidPath: /
Secure: NO
Expires: 2018-01-01 10:44 AM
Contents: dc5e44f10004d0ce4ca0d567c48cc19a11483296293
Browser: Safari
Notes:
• Cookie said there was 1 tracking cookie. It uses red type to indicated a tracking cookie.
• The information
_cfluid is the only underlying information in red.
• The expiry date is exactly one year from the time I first booted this morning (10:44 AM)
My results seem to be consistent with the first result in artie's first screenshot.
