Is svchost.exe a virus? if so can i just delete it from the processes tab to remove it?

some say they are network services or system under user name (this is all in windows task manager) and my antivirus just detected it as a threat so should i delete them all?
Dont delete it! Read...



The Svchost.exe file is located in the %SystemRoot%\System32 folder. At startup, Svchost.exe checks the services part of the registry to construct a list of services that it must load. Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services.
