I used to use MSE but went on a dodgy site (unknowing)and caught a virus, I now use ParetoLogic Internet Security and have found that brilliant.. I also use Super AntiSpyware and Mailwarebytes
How do you know Paretologic is brilliant? Did you try re-visiting the dodgy site to test it's worth?
Remember, NO AV or Malware program is foolproof, it's a constant daily battle for them against the virus writers and some days the virus writers win. So just because one product fails one time is no real reason to write it off.
As well as virus/malware writers the AV community's second biggest enemy is user foolishness or if not foolishness then ignorance. Most folk don't realise there's a veritable array of evil-minded so-and-so's out there in the wild trying to do you harm, most users seem to think the Internet is as lovable as the house on Pooh Corner. It's not, it's a jungle.
I presume you have the free copy of Paretologic?
Incidentally, a quick Google on Paretologic logic reveals many alleged scams, particularly something called Pareto Regcure, lots of disgruntled folk, so maybe a little caution is called for.
