    Good advice .. Although sometimes we screw up and we want more.
    I remember that I used kis and Avira for scans, a long time ago:)

    Some won't allow you to run 2 full AV at the same time.

    I was a repair guy long time ago, and i got so many systems to fix where 2-3-4 AVs were running...and when you try to explain to the users that isn't good, they won't believe you...

    True, and if they do not believe in the great Umbra of Emsisoft, imagine in me :p but I try to do what I can, at least here at home everyone has already learned about the rule of only 1 antivirus per computer :)

    One of my techs found a machine with 4 AV's recently.. All useless ones mostly, but layer upon layer of AV's.

    Not just antivirus, I bet some people do the same to firewalls (I'm talking about local firewall on the same computer, nothing to do with router firewall or UTM or whatever black box you may have).

    Good thing that even when I was a total noob, I never used 2 AVs at once.

    People still do this. I was talking to my friend who does repairs. He says he deals with this all the time. Average Joe's mentality is "Multiple AVs = multi-layered protection = better protection." Average Joe doesn't know any better.

    Would this be the same as ZAM + AVG Free AV? or would it be more like Avast + AVG?

    Right now, I have ZAM + AVG Free + Malwarebytes Premium + Windows Defender, running for my protection

    I was obviously not as clever as you :rolleyes:

    I was one of those people, like @Lockdown said, i went from no security really to too many, i thought the more i had the more i would be protected, guess who got infected ? :oops:

    a couple of years ago I installed 7 internet security just to check how many my laptop can handle and i had to reinstall the os.
    for time pass it is a good excercise to have more than one antivirus but for security purpose ,I think,it is better to have no antivirus install than having two
    by the way who has more chance to get infection a person with single partner or one with multiple partners

    Lack of storage space and resources was the main reason for me haha.

    This analogy fits perfectly! (y)

    Regarding #1: I ran Emsisoft Emergency Kit one time and it performs a deeper scan than my AV which only does on-access scan. I did not have EEK whitelisted so it would scan what EEK would access as well and fun fact it picked up things that EEK didn't (mostly PUPs). It also picked up all the malware in EEK's quarantine and deleted it right away. That being said, it was a massive waste of CPU cycles.

    I often find machines that still have the expired trial version of McAfee running along whatever.

    I remeber I installed 2-3 AV in childhood I learn lesson my pentium 4 desktop computer going super slow. Unistalling Av is pretty hard because system hang and I try many times and finally I unistall Av from computer. I remeber Umbra words he mentioned many times ComdoEmsisoft :D

    I have never installed two anti-viruses on one system, because it is related to troubles.
    this is not advisable.:oops:

    I remember seeing someone in a security forum, I don't remember if it was here or some other forum, who had 8 real time security programs running... and he was sure it was all working correctly and that there was no problem with his config... And nothing anyone said would convince him otherwise. I hope he never got locked out of his own computer with multiple blue screens.

    IMO all decent A/V software installation programs should check for existing A/V software and then either warn the user of the implications or, better still, refuse to install. You can't expect the average Joe to know these things.
