MSE, just like all other antimalware software, is unable to detect everything. Therefore I run scans with more than one antimalware program, especially if the computer is known or suspect of being infected.
I got my hands on one heavily infected computer. Initially it refused to run Secure-F (the standard antimalware software on that computer) as well as Spybot, because those were blocked by some malware. After running deep scans with Vipre and Ad-Aware, cleaning plenty of infections, the other two programs were able to run and detect more than a dozen additional infections.
