I read some of the other posts of people who had this problem - BUT didn't really see a solution. I have SF 15, Windows 7, and YES I have RX8 as a standalone as well as what came with SF 15 - and I ALSO have SF 12 STILL installed as well as SF 9 - (I won't delete them as this has saved me when SF 15 AND SF 12 goes wonky - which it does sometimes but I have my Trusty SF 9!)
This JUST started approx. 2 days ago - I think it was after the latest update I clicked on. Whenever I start up SF 15 I get the above msg. YES - I added BOTH exceptions to my Anti-Virus system - Kaspersky - did not work - I manually tried turning off ANti-virus and File anti-virus - NOPE! - I've attached a jpg of the msg that pops up - AND YES - I could JUST ignore it and go on - BUT it MUST MEAN SOMETHING - SO I am turning to the Forum.
