It is my understanding that Defender is just an antispyware program so this person should keep Webroot on it for the antivirus and not have Defender running
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 the others as stand-alone on demand 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.
Security vendors use different scanning engines and different detection methods such as heuristic analysis
or behavioral analysis
which can account for discrepancies in scanning outcomes. Depending on how often the anti-malware database is updated can also account for differences in threat detections. Further, each vendor has its own definition of what constitutes malware and scanning your computer using different criteria will yield different results. The fact that each program has its own definition files means that some malware may be picked up by one that could be missed by another.
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
as a result of the overlap in protection. These conflicts are typical when similar applications try 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 anti-malware 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. Generally these conflicts are more of an annoyance rather than the significant conflicts which occur when running two anti-virus programs in real time.
It appears that Defender is running all the time and I cannot find how to make it not do that
The version of Windows Defender
included with all versions of Windows 7
is part of the operating system so it cannot be uninstalled
. However, you can disable or turn it off.
