Avast Reporting Too Many False Positives

AvastpngI was without power for most of the afternoon and evening today. When the power company had everything fixed, the first thing I did was to head over to Twitter to see what I had missed. That’s honestly where I find out most of my news lately. On Twitter, I follow a lot of different people. Many of those are staff members and experts right here on GeeksToGo, as well as other security-related sites.

As soon as my Twitter homepage loaded, I started seeing tweet after tweet talking about Avast, and their horrible “oopsie” today with updates. Being the person I am, I started nosing around the web, trying to find out more. The more I read, the more disturbed and angry I became.

Virus definitions version 091203-0 which was released today is creating havoc on many unsuspecting users. It is reporting numerous legitimate files as being infected with Win32:Delf – a very nasty little piece of malware. For many users, Avast isn’t even giving them the option to “skip” actions against the supposedly infected files and programs. They are simply being moved to the “chest”, rendering them useless to the user.

If you do a simple Google search, you’ll see thousands of people complaining on all sorts of forums about losing programs, pictures, documents and the like due to this. People are outraged – and rightfully so. They have placed their trust in Avast to keep them protected, and to keep the things on their computer safe. Instead, Avast is making a mess of things and putting their information at risk.

We at GeeksToGo have long recommended the use of Avast to our users. Normally, it is a very good program. Everyone makes mistakes, yes. But to make one of this magnitude – is nearly unforgivable.

    Just wow... I never really used Avast! myself, but I know a lot of people that do. I better start getting ready for questions..

    I sure hope most of these false positives are really put in the chest, and not deleted (by either user or program)!

    This has cause me serious problems. I was being helped with a nasty piece of malware and a worm and was directed to download and utilize ComboFix. My Avast kept telling me it was a Trojan and aborted the download.

    Avast lit. Saved my PC just lastnight, I had a virus the one mentioned, and it locked my PC up 100%, I found from C-NET it has the win32:DELF-MZG
    I was downloading some programs off C-NET owned by ABC by the way, and most of the stuff, avast alerted me, one got in somehow and as I said almost destroyed my PC, thanks C-NET avoid them I have learned.
    It took 24 hrs of trying fix it pro rescue disk and comand promts etc I am learning so the 24 hours was a good learninf thing.
    I loaded safe mode and ran Avast it found all entries of the trojin and it was all over, it took a long scan ,but after words my PC was back up tp 100%
    I use avast and have never had any problems with it so far, Note if your on C-NET and it (avast) shows a trojin take my word for it , it is not a false thing it literally saved my Arss. I do not work for avast by the way, It is my fav by far.
    Screw C-NET owned by ABC they say all programs are spyware tested, not virus free, come on man c-net avoid.

    I received a false positive from Avast on one of my XP machines. Coincidentally, I had just did a clean install of XP and had installed Avast minutes after the machine was running only a week before.

    The PC had barely been online since then so when it said that a file from TuneUp utilities had been infected with Win32:Delf, I was pretty sure it was a false positive. Of course I did a little research before coming to the conclusion.

    As bad as this is, I'll still keep Avast. It seems to me that every anti-virus program has it's issues. Up until now Avast has treated me well and hasn't cause me any heartache as other anti-virus programs have. 🙂

    I am now struggling because up-to-date Avast missed Sysguard, the latest version, and kivereza.dll.

    These malwares are particularly serious because they contain code which prevents the running of Malwarebytes, which is my second line of defense.

    So now, I struggle.

    I've not had a problem with avast. That being said, I've found problems with every AV I've ever used (Avira, Avast, and especially Norton). None are perfect, and I ALWAYS have more than one line of defense for that reason alone. MBAM professional version's protection system is a good backup, I've found.

    David,

    Don't forget that you cannot run more than one Antvirus program at a time because they will conflict. Same goes with Firewall applications.

    But you can use multiple anti-spyware programs on the same machine, as they will not conflict.
