    Should "false" Positives Be Ignored?


    I just installed an update for a video recorder that I use (GETFlv) and Comodo popped an alert for the Trojware.Win32.Spy.Banker.Gen@1. Most of what I found Googling are non-English returns, but one I found from Virus Total indicated that only 4 out of 43 scanners balked on this program, and each of those four identified it by a different name.

    https://www.virustotal.com/file/4608...53af/analysis/

    That makes it appear that it is a false positive, but considering the nature of the trojan that it sees:

    Steal bank account information from your PC, and:
    The Trojan can be configured to perform any of the following actions:
    Captures Screenshots
    Checks the title of active Internet Explorer Windows to see if it matches any preconfigured strings.
    Delete all the URL cache and cookies.
    Display a fake login screen for certain South American banking sites
    Gather email addresses
    May display a preconfigured message box
    May search for and delete predetermined files
    Record keystrokes
    Register itself as a service
    Replace the contents of hosts file
    Search for and deletes files
    Send an email with the collected information to the remote attacker
    Monitor active Internet Explorer windows for user access to various web sites, particularly those of financial institutions.
    I would like to be sure. Some might say to just not use the program, but it is quite expensive, and one that I use almost daily, so I wouldn't like that idea.

    Am I just making too much of it or not?

    Well... the trouble is, figureing out if it is really false or not .

    Of course if it is a false positive then yes you can ignore it, but how do you know? Frequently with new virii or morphing ones, only a handfull or even one av scanner will even pick it up and it may be legit. On the other hand I've written code myself that managed to trip at virus scanner by accident in the past. There are now so many signatures and code is a fairly random set of bytes that it does just happen sometimes.

    The only way to really get to the bottom of it is to contact the maker of the software and work it out with them... It's not unheard of for a companies build machine to get infected and then produce infected files for DL

    Edit: Just a couple months ago I got a driver disk for a 4x2 HDMI switch that MSE flagged as having a virus on in the driver on the CD! Company was not responsive and so I just didn't install it...

    I don't use Comodo, but does it have a link to report what it found as a virus inside it's scanner program?

    Yes, I sent an email to them about this, but the problem with that, is if the programmers were the type that would design their program for malicious purposes, they wouldn't admit it. I have not found that this company is particularly responsive, regardless of the nature of an enquiry, but since I have been using this program for a couple of years, I tend to doubt that the program is malicious. It's just that rather than have any suspicion, I would like to feel certain that it is safe.

    Yes, I did send it to them, but I'm more interested in a report to me, than to them.

    I wasn't suggesting that the programmers themselves did it on purpose, but it's possible that they unknowingly have an infected build machine OR it may be that by pure accident this compile triggers the signature detection.

    In both cases there may be something they can do to fix it. Like I said, it happened to me at an old company and we were notified and we fixed the problem and issued an update. (Though I admit that I seem to work for the only companies in the universe that actually care when someone calls in with a problem).
