I was told my antivirus would scan even if my computer is turned off. This doesn't make sense to me... Is this true? Will my computer scan when the computer is off?

Will my antivirus scan even if my computer is turned off?

Simple answer, NO.

As Anti-virus is a program that runs on your machine, if it's off it won't work.

It would not work if your computer is off


But who told u this

Yes it will scan when you turn it on again. Keep it on auto scan.

Is a lightbulb on when it is off?

You can scan your hard drive in another computer such that your operating system is not running
