  • Virus! Router keeps dropping out - Locked up XP machines??

    Hey

    Ok running Sophos anti virus.

    In the office today and 5 of the
    Xp machines in the room all lock out with test1 account apparently using the computer

    Go to the server and 13 virus appear to which I remove and restart the server

    All appeared fine but then the Internet started to play about. Pinged the router and I am getting constant drop outs ever few seconds.

    I have isolated the router and it pings fine so not an issue with that.

    Any ideas folks? Badly stuck here!

    Unplug all machines that indicated they were infected
    Run an online scan from somewhere like these on all other machines.

    (and others).

    I would, as a precaution, assume that Sophos isn't detecting something. Is it up to date, current version etc?

    Can you isolate what is affecting the router? If you can prove the router on its own is ok then disconnect everything else and add in one at a time.
    Really worth running up to date AV on everything asap though.

    Mcafee also have their stinger tool which has a very limited but recent list it can help with.

      Bitdefender works well too.

        Hmm, I heard good things about Sophos but in reality no AV solution is perfect.
