        At work we spent a couple months this summer dealing with weekly virus infections of DWH*.tmp "generic trojan" on half of our computers, and per policy if the guys running the symantec servers see two or more hits on a single computer, that computer must be wiped and reinstalled.
        Yeah, it took us two months to convince them it's a problem with symantec finding it's own temp files, not an actual virus.

        • But it always started with an actual hit (or two), as it would mostly double with every scan (the odd extra actual hits would cause bubbles in the progression). So when I had this problem, I had the machines nuked too. Thankfully it was rare here (there were only a couple repeat offenders who didn't end up getting JRE afterward).

        Norton Ghost is a discontinued drive replication program that was loved by sys admins to copy exact drive states so any hacked machine could be simply restored to a state where it was known to be good. Other tools have taken over since then, and that's why the program went away.

            For now. At one time Ghost and Drive Image were competitors, with Drive Image actually being the more powerful and less expensive of the two. Then Symantec bought Drive Image, rolled the technology into Ghost, and made it almost entirely unusable. After attempting to use it twice I found a freeware replacement and never looked back. This replicated my experience with WinFax and some other product that doesn't come to mind immediately.

    With occurrences like these it's no surprise people sometimes think antivirus and security recommendations consist of 75% FUD and 25% common sense.

    How many of us have seen just about every damn thing we download labeled as some kind of trojan or other?

    It's commonplace on file sharing sites to see outright mockery of those who raise alarms about the scary alert their AV just popped on those files; that's how bad antivirus programs get.

    I understand that sometimes shady files do contain viruses, but nevertheless I've seen claims from major security vendors and from Microsoft that the vast majority of illicit files contain viruses. Seems like I'd have noticed some missing money, some funny things on my credit report, or some suspicious traffic in my router logs if that was true, but they've all been squeaky clean. And I used windows XP SP3 with no firewall or antivirus until this year.

    Bottom line, I should be using better protection and it's possible I've had some viruses, but if I did they clearly haven't harmed me yet. And it's still difficult to distinguish the level of actual threats from the hilarious mistakes and massive, obvious disinformation campaigns going on.

      Given the turnover speed in AV development, it's not only likely but pretty much a given that their whitelist box wasn't up to date. Usually, testing your new signatures against the whitebox takes close to your update cycle time.

    Avira has this bad habit of detecting some files as malware (e.g. scene game cracks) although they don't exhibit infection. I personally submitted a few of these files to Avira for review and they confirmed no infection is found, but it's an "illegal" modification of a legit file so it stays as flagged for warnings in their VDTs.
    Now I'm not a conspiracy theorist but this reeks of shady deals to "reduce" piracy.
    I should change my Avira Free antivirus but I'm too lazy to go through a couple restarts and installing something else. Maybe Avast, which I gave up because it had this voice update notification enabled by default and scared me to death one night by yelling at me "VIRUS DEFINITIONS HAVE BEEN UPDATED!".

        Malware gets tested before being sent out, much like AV kits. And much in the same way: Where AV kits are tested for whether or not they detect all known threats, malware is tested whether it gets detected by the most common AV kits. And being bundled with Windows means that this AV kit MUST be evaded or defeated by the malware you create. Else, your chance for infectio

        • It's not bundled with Windows and you're not prompted to download or install it when you're installing the OS. You actually need to visit a website to download it.

          As far as I know, it's not even the most poplar anti virus software out there, so the bad guys are probably more concerned with the 3rd party AV packages.

    • Avira let's you pick the level of sensitivity- the highest sensitivity has the most false-positives. There are about 5 or 6 levels of sensitivity.

      Personally I'd rather a false positive every once in a while than to ever get a false negative.

      • Sadly, the false positive rate in Avira on highest setting is like setting the metal detectors at airports to a level where they can pick up the hemoglobin in your blood cells...

        • I use Avira on the highest setting. I've probably had 2 false positives in the last 12 months. Probably about 5 in the 2 or 3 years I've been using it.

    • perhaps a game crack included their .dll for this very reason...

    • Avira has this bad habit of detecting some files as malware (e.g. scene game cracks) although they don't exhibit infection.

      Avira scans for both known malware in its database, and uses a heuristical algorithm to detect possible but unknown malware. So it will tend to flag flies other virus scanners miss. This can be bad as you found out, but it can be good as it can catch new viruses before they're in anyone's database. I don't think any of the other free antivirus software has this feature, though sever
