    Be cautious who you listen to when it comes to testing AV software. In that AV Comparatives study, note that they do take money fro the companies whose products they are testing, which leads to the possibility of bias.

     

    In addition, their methodology was poor. They tested with "477 Mac samples (most of them belonging to the FlashBack and FakeAlert families)," which basically means that they mostly tested with only two malware families, both of which were extinct at the time of their testing.

     

    Now, as to Avira, it got good results (as far as detection rates) from my own testing. However, it has frequent problems with false positives. I cannot recall any other anti-virus software that has ever been reported to me for causing false positives, yet I'm fairly frequently barraged with reports of Avira identifying legit system files and other things falsely as malware. That's a pretty significant issue. If you choose to use Avira, do not allow it to delete or quarantine anything without checking with an expert first!

    You are pretty computer savy but there are probably 100 users that don't have a clue to every 1 like you.

    Which is why many of us try to educate them on being a smart computer user. Far better to use you head and the tools built into every computer that prompt a thoughtful decison than to install A-V software and believe you don't have to worry about such things.

    Well,

    After reading all the opinions and searchin the Internet a lot, I decided not install any antivirus with real protection on my iMac.

    I'm going to use some precautions and some security extensions to my browser: BitDefender TrafficLight, Do Not Track Me and AdBlock Plus.

    Once a week I intend to scan my system with BitDefender Virus Scanner which is free and not offer real time protection.

    Thanks for your opinion and thank for all try to helped me! It was really very important!

     

    Regards!

    BitDefender's not much good at detecting Mac malware. See:

     

    http://www.thesafemac.com/mac-anti-virus-testing-01-2013/

     

    If you want a free scanner for manual scans only, you could try Intego VirusBarrier Express from the App Store. It's free and has quite good detection rates.

    Thomas,

    Thanks a lot for your suggestion!

    I will definitely change my on demand antivirus scanning tool from BitDefender to VirusBarrier Express.

    I''ve been using Avast! for less than a month (that's because it is installed on a brand new MBP). So far so good =)

    Great! What all has it done for you during that time?

  • Tobi Damaris Level 1 Level 1

    Well, it successfuly detected 1 windows virus and put it in their sandbox, it filtered my incoming emails and blocked all emails which tainted with trojan in attachments. It updates its virus definition daily. And it shows me which website is trustable thru WebRep :)

    Note that, in my experience, avast! has a very serious problem with false positives. I have lost track of how many people I've been contacted by after avast! identified perfectly legit system files as malicious. If you choose to use avast!, I strongly advise not allowing it to quarantine or delete anything automatically!

    How are you using the term "virus?" Do you mean malware in general? Yes, Macs can be affected by malware, no one is saying that can't happen, but the route taken by most malware authors is to trick a user into installing something. It's much easier than trying to get directly into the system (which has been done via Java, not JavaScript, which you should have disabled in your browser.)

     

    As for "virus" qua virus, there have been viruses created for OSX, but only under laboratory conditions, and there are no known viruses for OSX circulating, that we know of. Again, it's much easier and more profitable to just trick a user into installling something.
