[FSX crashes with fsuipc4.dll module]

Hi Pete.I installed on my pc the latest registered version 4.937.But every time FSX opens(i open it as administrator),a window appears with a security alert,to run or no the fsuipc4.dll module.If i press run then another window appears that asks to me , to assign this as trusted software.If i press yes, the FSX crashes with a message of fatal error .This strange behavour begun 2 days ago with another software.My antivirus is KIS version 15,but the FSX is excluded from scanning.Please help to bypass this frustating situation,because FSX doesn't opens at all.Thank you .Bill.
