Microsoft Security Essentials Overview
is basically a stripped-down version of OneCare aimed at users who either canít or don't want to pay for antivirus/anti-malware software.
Using more than one anti-virus program is not advisable
. The primary concern with doing so is due to conflicts that can arise when they are running in real-time mode simultaneously
and issues with Windows resource management.
In contrast, 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. Sometimes you just have to experiment to get the right combination for your particular system as there is no universal "one size fits all" solution
that works for everyone.
