BleepingComputer.com: On demand scanners

Now i run nod 32 for my real time but i am wondering since i have superanti,mbam, and a-squared for my on demand do they conflict if i use them all at once for on demand scanning since i usually go to sleep and let them do the scanning or should i run each separately to get better results(including nod32).

It is best to use one at a time to avoid conflicts

As a general rule, using more than one anti-spyware program like Malwarebytes' Anti-Malware, SuperAntispyware, Spybot S&D, Ad-Aware, etc will not conflict with each other or your anti-virus if using them as stand-alone scanners. In fact, doing so increases your protection coverage without causing the same kind of conflicts or affecting the stability of your system that can occur when using more than one anti-virus. The overlap of protection from using different signature databases will aid in detection and removal of more threats when scanning your system for malware. However, if using any of their real-time resident shields (TeaTimer, Ad-Watch, MBAM Protection Module, Spyware Terminator Shields, etc) together at the same time, there can be conflicts when each application tries to compete for resources and exclusive rights to perform an action. Additionally, competing tools may even provide redundant alerts which can be annoying and/or confusing. Keep in mind that you can overkill a system with resource heavy security programs that will slow down performance.
