Saulius i would say that with all the extra scanners you have on your system is major over kill, also dont know where you heard that rubbish the the paid protection of malwarebytes is no good because thats a load of bull#### and if superantispyware became malicious on your system it is more than likely because of all the other crap you have on there.
No point even mentioning threatfire because it is not compatable with avast’s behaviour shield, spybot is not recommended as it scanning capabilitys are outdated nowdays, even glary utility’s is not recommended because it can mess up your system so is alot safer to use ccleaner and a good defragmenter (defraggler is excellent with boot time defrag included), i dont know to much about spyware terminator these days but a few years ago crawler software was just as bad as iobit’s.
I think what has already beem mentioned to the op would be the best to keep his system light fast and well protected imo.
