But it's a legit contender with the AVs now a days. Windows Defender is a lot better than is used to be. Now if you're downloading files off Piratebay and torrenting, purposely going to shady parts of the web then yeah I'd purchase something greater than Windows Defender.

We have great password managers available today as well. There's a lot of great security and privacy extensions to help like UBlock Origins, HTTPS Everywhere etc. All the top web browsers have really good security baked into them compared to the Windows XP days. I think it really depends on how you use your computer.If you're browsing the same safe sites, purchasing games from Steam or other game stores (not Piratebay), you maintain good email security habits (checking links before you click etc.) and good email surfing habits. Always liked the way the guy in The PC Security Channel tests the AVs. Like others say, you must be a bit more carefull when using WD. I liked Bitdefender before, but found out that it takes alot of resources and does slow down the PC. It all depends on how far you trust 3rd party AVs. Some AVs are better than others not online.WD is also less intrusive than some paid AVs. We see from the video that WD relies alot from cloud. I go to these sites to have some idea of AV (test a bit old, next one is next week)Windows Defender also rely on browser for first line defense (phishing, download filtering).

Is free malwarebytes good enough
