    Best free file (/directory) scanner for detecting malware?


    Hi

    I am using Windows Defender to protect my PC.
    I am suspicious that it may have missed some malware and I would like to scan particular directories.
    I understand that it is a bad idea to have more than one anti malware application running simultaneously.
    So I would like to install something to catch viruses/Trojans/spyware etc with on-demand scanning of individual files & directories (and maybe my entire PC but that is less important right now)

    Any recommendations?

    Thanks

    I recommend using Avast! because of my recent experience with it. I had Webroot installed and Avast! noticed a virus Webroot had missed.

    Is it possible to install Avast! without it scanning everything all the time?
    i.e. Is it possible to run it purely 'on demand' ?

    I ran MalwareBytes and it found some stuff (yikes!)
    - PUP.Options.NotChromeRun.A
    - PUP.Optional.ProductSetup.A
    - PUP.Optional.ProductSetup.A
    - PUP.Optional.WinYahoo.A

    Does anyone know if any of those are serious?
    Either way it says it has quarantines them so I am hoping it's all under control. Fwiw, I also ran SuperAntiSpyware which found nothing...

    Like a fool I let a young teenager loose on my PC and I have no idea what he got up to.

    Yes, the free version is actually entirely on demand. You can't use real-time protection without paying. You can also adjust what you scan, but I'd probably do a full scan first and then scan whatever fits for you as needed. As for the PUPs found by malwarebytes, a PUP in and of itself isn't typically malicious, but I'd still remove them. Odds are you never installed them yourself anyway.

    I use BitDefender Total Security.
    Its the best antivirus program I ever used.
    In the past I wasn't careful on the internet and with torrents I took viruses and malware on my laptop.
    McAfee, Avast, AVG and a few others couldn't detect them and were a huge impact on the performance.
    I had to install windows again several times, eventually I found BitDefender and wanted to try it out a little bit.
    Because I like it to have a lot of setup in the beginning I installed BitDefender Total Security.
    After the first scan it removed a lot of infections without asking what to do with it or even a reboot.
    Since then I have only used BitDefender Total Security with Malwarebytes. I am not capable of defeating these 2 programs, doesn't matter how much I try to get any viruses and malware and I'm very good at getting them.
    Also, BitDefender doesn't have any impact on performance if you set it right up.
    I've played a little with updates, within how much time the definitions of malware and viruses needs to be updated and thats the only thing that'll take impact on the performance if you set it without enough delay or too long delay.

    A)
    @Axe0 - OK but if I install "BitDefender Total Security" that will be doing real time scanning etc yes?
    i.e. I would need to uninstall Windows Defender because you shouldn't have two real-time Anti-virals working simultaneously, yes?
    If so that's a slightly different conversation. I was looking for an on-demand scanner.
    Also BitDefender Total Security its £59.95/year. That's quite a lot when you can get so much for free.

    Is there a way to install Malware Bytes on an on-demand basis?


    B)
    @thebeesknees - which version of AVAST are you using and how much are you paying?


    Thanks both

    P.S. I know it proves little but number of active users is intriguing:

    AVG is one of the top 10 retailers in the UK !!
    With 200 million monthly active users worldwide, apparently.
    (AVG - Security Technology | News Release)

    And free version has 80 million users:

    Bit Defender claims to have even more "500 million home and corporate users across the globe" !

    AVAST has
    "230 million active users worldwide"
    https://www.avast.com/en-gb/about

    And free version has 50 million users:

    Yes, it is real time.
    No, you don't have to uninstall Windows defender because you cannot uninstall it.
    Windows defender will be deactivated when you install another AV program.
    I use Total Security, but I recommend the free AV program for you.
    Malwarebytes free is what you are looking for.

    Axe0 - like I say in post#4 I ran MalwareBytes and found some PUPs.

    I'd quite like to run some other on-demand stuff to see if anything else comes out of the woodwork.

    I'm not completely ready to abandon Windows Defender. No offence but I'd like to see some further second opinions on BitDefender. Fwiw, last time I looked into it I concluded that most of the "expert" reviews were extremely biased....
