    When I initially purchased a license for NOD32 (Preconfigured with BlackSpears Recommended Settings) I tested it at EICAR. Sometimes I would get a splash page from NOD32 and sometimes I would only get something like "Page Not Found", etc. Basically I would not be allowed access to any file at EICAR.

    I frequently look at discount/deals type websites. Almost all of the time there are no files to download. However, yesterday they had WinRAR 3.51 with free license. I filled out the form. They sent an E-Mail with the download link. When I clicked on the E-Mail link my BlueCoat Web Protection Filter denied access. I was stubborn and temporarily bypassed the Filter. There was tab for a link to the free license. When I move the mouse over the tab it was labeled as Java script. I repeatedly clicked on the link and there was not response. Is this link not working be what NOD32 does in that case to prevent infection?

    I looked at forum posts for that website. Only one person reported that the actual download file had a Trojan in it. The following is what one person out of 100+ posted:


    I followed the instructions and links from the email I received.

    As soon as I installed the program, Symantec Anti-virus found Trojan.Dropper in the file: Default.sfx in the WinRar folder.

    Here's Symantec's page re: this trojan:

    It's a low-level threat, but the fact that I've downloaded any kind of threat really bugs me.

    Anyone else run into this?

    It sounds more like you have a Javascript issue than anything else. When you click on the "Smilies" in this forum, do they work?

    Cheers :D

    I've often wondered, sometimes out loud, how people get infected all the time.

    I no longer wonder.

    Default.sfx is not a trojan, never was never will be.
    In previous versions of WinRAR the file was packed using UPX (archives too) but they removed it since most AV-vendors didn't bother fixing their False/Positive. The new version (3.51) only TheHacker is detecting it as: Aplicacion/NetCat.

    And if you do not want to have Javascript enabled all the time, I suggest you download Firefox + NoScript extension.

    Try submitting the suspicious file to or . These are two online services that will run the suspicious file through several different virus scanners. It could be that the 100+ posters were correct, and the 1 poster had found a false positive.
