    Answers to frequently asked questions. Please consult
    this list before asking a question that may be answered
    here.

    Before you post, a reminder - it is advisable to use
    a fictional email address when posting to this board.
    If you use your real email address, you open yourself
    up to receiving spam, virus infected emails, and more.

    Answers to your questions will be posted here as a
    reply to your original message, and not emailed to you.

    Please remember, if you are asking for help with a
    virus, it helps us to help you if you tell us as much
    detail as possible, including the name of the virus as
    was told to you by your antivirus software.

    Q. My computer keeps shutting down - something about
        RPC failure. What do I do?

    A. You have been lax in keeping your computer up to
        date with antivirus software and more importantly
        in this case, critical security updates available
        from Microsoft. A virus has been released which
        takes advantage of a security flaw in Windows 2000
        and Windows XP. Microsoft released a fix for this
        weeks ago, but you haven't installed it. See the
        further down the rest of this list to find out what
        to do, including advice about antivirus software
        and WindowsUpdate.

    Q. I've recieved an email telling me that I have been
        infected with a virus called JDBGMGR.EXE and that
        I should delete it, and then warn everybody that I
        know about this. What should I do?

    A. The email you have recieved is a hoax, and no action
        should be taken except to delete the email that made
        these claims.

    Q. Oops, I've already deleted JDBGMGR.EXE - how do I
        get it back?

    A. You don't need to. The file is only required by
        software developers who program in the JAVA language.

    Q. I've recieved an email that warns me about an email
        titled either "It takes guts to say Jesus", "An
        internet flower for you", or "Life is beautiful".
        What do I do now?

    A. Nothing. The emails you have recieved are more
        hoaxes, all of which have been around for a very
        long time. I suggest consulting one of the
        following websites for information about hoaxes:
        http://hoaxbusters.ciac.org and http://snopes.com

    Q. I've recieved an email reply from 'Microsoft' with
        an attachment. I didn't email them, and my virus
        checker tells me the attachment is infected with
        a virus! What do I do, and who at Microsoft should
        I report this to?

    A. The email is not from Microsoft, as their policy is
        to never send files by email. The email you have
        recieved is the result of someone you know being
        infected by a virus as a result of opening an email
        just like the one you recieved yourself. Delete the
        email.

    Q. A file called ~ keeps appearing on my desktop or in
        other places on my computer. It appears to contain
        my address book. Do I have a virus?

    A. No. This file is produced as the result of a bug in
        the current version of Outlook Express. Microsoft
        are apparantly aware of the issue and will release
        a patch sometime in the future.

    Q. I think I might have a virus, how can I tell?

    A. With antivirus software. If you don't have any, you
        can get some for free from http://www.grisoft.com

    Q. I already have antivirus software but it didn't
        find virus X, why not?

    A. To ensure your antivirus software can be able to
        detect the latest virus threats, you need to keep
        it updated. Many antivirus software packages come
        with an auto-update feature. Ensure it is working,
        and if not then check the website of it's developer
        to see if a manual update is possible.

    Q. If I install antivirus software and keep it updated,
        is that all I have to do to keep my computer protected?

    A. No! Antivirus software will only detect and prevent
        infection by viruses. There are lots more nasty things
        out there on the internet that are just waiting to do
        the dirty tango with your computer. For one, you need
        to keep your operating system up to date with all the
        latest security patches. This is a free service
        provided by Microsoft. All you have to do is go to
        the WindowsUpdate website, scan your computer, and
        apply any updates that are available. You can find it
        at http://windowsupdate.microsoft.com

    Q. So, if I install antivirus software, and keep my computer
        up to date with security patches, is that me safe now?

    A. Not completely. You should also install a firewall.

    Q. What's a firewall?

    A. A firewall acts like a bouncer on the door of a nightclub.
        It controls what can enter and leave your computer.
        You can get free ZoneAlarm from http://www.zonelabs.com
        An alternative is Sygate Personal Firewall free from
        http://smb.sygate.com/products/spf/spf_ov.htm

    Q. I keep getting pop up messages while I am on the internet,
        what can I do to get rid of these?

    A. There are two types of popups. One uses the 'messenger
        service' included with Windows 2000 and Windows XP. To
        rid yourself of these, install a firewall (see above).
        The second type of popup is triggered by web-pages you
        visit. These can be controlled by a popup stopper.
        You can get one free from http://www.panicware.com

    Q. My browser home page has been taken over by another
        website! Also, when I do searches I get taken to a
        website I didn't want to go to! What's up?

    A. Your browser has been hijacked, and your computer
        probably is also infected with Spyware. You can clean
        these nasties from your computer with some software
        called Spybot Search & Destory, free from
        http://www.spybot.info

    Q. After I updated my computer with the security patches
        available from WindowsUpdate, I was no longer able to
        open attachments in Outlook Express! Why not?

    A. This is by design, and was implimented to try and
        control the ever-increasing spread of virsues. If you
        are absolutely sure the attachment is safe to open,
        you can disable this blocking by going to Tools,
        Options, Security, and unticking Do not allow attachments
        to be saved or opened that could potentially be a virus.

    Q. I have been infected with Virus [insert name here]. How
        do I go about removing it?

    A. Most antivirus software is designed to prevent infection
        by a virus. If the software was not updated, and the
        virus was able to infect your computer, you may find that
        your antivirus software is unable to remove it from your
        computer. In this case, do a search of the internet for
        '[insert name here] removal tool'. Replace [insert name
        here] with the name of the virus that you have been
        infected with. This should give a result directing you
        to a page with a tool that you can download and run that
        will remove the virus for you.
