IMHO, using on-demand scanners principle is to scan your system with signatures different from what your real-time antivirus use, so using KVRT with KTS will not give you any benefits, NPE and EEK have different signatures, you can try all products mentioned by other members and see the results by yourself.
For me, I prefer NPE over EEK, just because it is smaller and faster, but be careful with false positives.
