While common sense should always be your first line of defense against malware and hackers, a dependable antivirus solution can save the day when common sense fails. Even if you consider yourself to be an experienced computer user, you shouldn’t underestimate how cunning malware authors can be in finding ways how to deploy malware without anyone noticing.

The best antivirus software won’t slow down your computer nor cost you a lot of money. What’s more, you most likely won’t even know that you have it installed until it detects a threat and prevents it from ruining your day—and potentially even your whole life in the case of banking malware, such as the notorious Zeus trojan, which was designed specifically to steal banking credentials and overcome two-factor authentication.

It’s only when Windows Defender detects a real threat when it alerts you and lets you decide how you would like to proceed.
