As a general rule
, using more than one anti-spyware program like Malwarebytes' Anti-Malware, SuperAntispyware, Windows Defender, Spybot S&D, Ad-Aware, Spyware Terminator, etc. will not conflict with each other or your anti-virus if using only one
of them for real-time protection and others 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, competing tools may provide redundant alerts which can be annoying and/or confusing as a result of the overlap in protection.
If using multiple 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. They may identify the activity of each other as suspicious and produce alerts. Further, your anti-virus may detect suspicious activity while these programs are scanning (reading) files, especially if it uses a heuristic scanning
engine, regardless if they are running in real-time or on demand. The anti-virus may even detect as threats, any malware removed by these programs and placed into quarantined areas. This can lead to a repetitive cycle of endless alerts or false alarms that continually warn a threat has been found if the contents of the quarantine folder are not removed before beginning a new security scan.
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. mvps.org
is no longer recommending
Spybot S&D or Ad-Aware due to poor testing results. See here
- (scroll down and read under Freeware Antispyware Products)
. Ad-Aware has even been placed into the Installers Hall of Shame
for bundling and pre-checking Google Chrome during the installation. Also read Lavasoft Turning to the Dark Side?
written by a former volunteer (now a MVP) who provided support for Ad-Aware but no longer uses the program.
As for Spybot S&D, most people don't understand how to use TeaTimer
and that feature can cause more problems than it's worth. TeaTimer monitors changes to certain critical keys in Windows registry
but does not indicate if the change is normal or a modification made by a malware infection. The user must have an understanding of the registry
and how TeaTimer works in order to make informed decisions
to allow or deny the detected changes. If you don't have understanding how a particular security tool works, then you probably should not be using it. Additionally, TeaTimer may conflict with other security tools which do a much better job of protecting your computer and in some cases it will even prevent disinfection
of malware by those tools.
