VSE 8.8 has Anti-Spyware integrated into it. So it's no longer a seperate plugin that is required .
(The post above is slightly confusing, but correct - Originally Anti-Spyware was sold as a stand-alone product (if you didn't have McAfee AV installed), and also as a plug-in for McAfee AV if you had it installed..
The stand-alone product is end-of-life. The plugins (for VSE 8.5 and 8.7) are still in support. )
So if 8.8 is installed - then you have Anti-Spyware. Not sure why you are seeing what you're seeing -- I'm not near my EPO server to double check, but I would expect that what you are seeing now is correct behaviour.
That makes sense as to why i cant see any anti spyware installations in my queries
