multiscanning
{{Use dmy dates|date=March 2025}}
Multiscanning is running multiple anti-malware or antivirus engines concurrently. Traditionally, only a single engine can actively scan a system at a given time. Using multiple engines simultaneously can result in conflicts that lead to system freezes and application failures.[http://www.smartcomputing.com/editorial/article.asp?article=articles%2F2003%2Fs1407%2F38s07%2F38s07.asp Clash Of The Antivirus Apps].

Reason
Testing agencies published results showing that no single antivirus engine is 100% effective against every malware threat.[http://www.gfi.com/whitepapers/why-one-virus-engine-is-not-enough.pdf Why one virus engine is not enough]. GFI White Paper. gfi.com[http://www.av-test.org/certifications.php AV-TEST.org]. AV-TEST. Retrieved on 2012-02-29. Because each engine uses different scanning methodologies and updates their malware definition files at various frequencies, using multiple engines increases the likelihood of catching malware before it can affect a system or network.[http://blogs.technet.com/b/forefront/archive/2007/10/19/the-advantage-of-multiple-anti-virus-engines-on-server-products.aspx The advantage of multiple anti-virus engines on server products – Forefront Team Blog – Site Home – TechNet Blogs].
