the EmbassySecurityCheck.exe is a program on your PC from Wave Systems Corp.
thatis checkmg for updates and so on.
However some Malware can rename files so I recommend that you do a clean up and a malware scan.
To do this can you clear out your cache folder again ie: Run CCleaner
(Note in CCleaner: go to >options > advanced > Uncheck "Only delete files in Windows Temp folders older than 48 hours").
Now can you scan for Spy/Malware there are a number of programs that you can use for free Malwarebytes' Anti-Malware
is one of them that i recommend after running the program you can post the logfile here.
