    MCafee vs Windows Defender?


    I am currently using Windows Defender in both of my home PCs. My ISP (Cablevision aka Optimum Online) now offers the full McAfee AV suite for free.

    Looking at some test data, McAfee is not the greatest, but it has a better protection rates than WD. It is also said to use more system resources than other AV suites.

    Any experiences, opinions, or advice will be appreciated!

    My PC came with McAfee so I used it for a year, it worked well but was quite a RAM hog and slowed the machine down a bit at times (mainly if it was doing a scan)

    When the year came up I didn't want to renew at the price of it so thought I would try Windows Defender (been using it now for 3 months), I am getting better performance now using this and so far it has not cuased me any issues

    For home use Windows Defender is ample and use what is between your ears. My bank offered McAfee, I tried it and it wasn't long before I uninstalled it seeing that it was a resource hog and caused other issues in my system.

    Suggest you uninstall McAfee using their removal tool if you have already installed it.

    I would rather not use anything than use McAfee. It is inefficient and ineffective. Almost every infected PC I clean up has McAfee, Avast or AVG on them and it obviously didn't prevent these infections. I know that no product is 100% effective, but these products aren't even close. I test AV and manage AV and endpoint security for 200k devices in a corporate environment for a living, so I'm not an expert but I've seen a lot....

    Thanks for the replies. I think I'll stick with Defender. My PC seems nice and snappy right now and I'd like to keep it that way, besides, I've never had an infection or problem with Defender. I was just tempted by the "sumthin for nuthin" syndrome. :-)

    You forgot to add Norton to that list The only Norton product I will even touch is Norton Ghost.

    I concur with azasadny on this one. McaFee SiteAdvisor, PRO, all of them just are not that...good. They are inefficient as he said. I will say this though the Enterprise version has some amazing controls and most local/state governments use it. That's probably also though because of the price they are offered/and also the free virus removal if they get the platinum contract though lol...I work for the state government and we use McaFee 8.7i which is pretty sweet.

    Edit: oh yeah...and McaFee overall takes up way too many resources!

    Windows 8


    Having a dad that was a system administrator and me likely going to profess into computer engineering, I kind of know about this stuff. I personally hate McAfee (before all of you begin to hate me, read on) because it uses a lot of resources, some research I have done to make sure that my information is correct is that McAfee takes up almost 85% of your resources after only being used for about 30 minutes, also from my own experience with McAfee it can take up to 100% of your resources on boot. Using Windows Defender is very nice to use because it takes hardly any resources, its super fast, super easy and super effective in my tests with Windows Defender I ending up with around 7% of my resources used after 30 min. If you still don't trust Windows Defender then I would recommend installing and testing AVG or AVAST both are very effective and promising.

    I've used MS Security Essentials for about 10 months on my old Windows 7 computer and Windows Defender on my new Windows 8.1 computer for 2 months, both along with Malwarebytes. All without a single virus infection.

    Our cable provider, Consolidated (use to be SureWest), provides free Kaspersky 2014. I've tried that on my two computers and removed it after about a week because it just bogs them down and takes up too much system resources. At times it would use 100% CPU on both machines and wasn't even scanning at the time.
