Safe Computing

  • Here are some tips on how to keep your PC healthy and on the Internet.

    Protect Against Viruses

    Virus Protection is a MUST! IUP offers Mcafee Enterprise Edition for free to all IUP students. You may use another antivirus program if you wish.

    Here’s how you download Sophos Virus protection:

    1. Start up your web browser and go to IUP’s antivirus page. Read through the website. It explains how to download this software.

    Note: If you are using Norton Antivirus, make sure you update it regularly. If it is not updated it will not pick up new viruses. If you do not have the update plan with Norton to update their antivirus software, we recommend you remove Norton Antivirus and install Sophos.

    Secure your PC

    If you have Windows NT/2000 or XP running on your PC make sure you have an administrator password set! Check on this by clicking on logoff under the start menu and then use “administrator” as your username and don’t enter a password. If this lets you log onto your PC then you don’t have a password setup. Hit <CTRL><ALT><DELETE> and choose “Change Password” to setup an administrator password. We have had a number of PCs compromised because the PC was not secure.

    Another way to ensure your PC doesn’t get a virus is to create an account without administrator rights and use it instead of logging on as administrator. This way, if you download a virus it will not have administrator rights and won’t be able to cause as much damage.

    Make sure you are up to date with all Windows updates and security patches. The Windows update page will check your PC and help you install any new updates and patches you might need.

    Don’t Use File-Sharing Programs!

    Most file-sharing programs such as Kazaa have other programs that come with them and get installed when they are first setup. We have found that many of these other programs, also known as spyware, can be harmful to your computer. If you have installed file-sharing programs you can check to see if they installed spyware by running a program called AdAware. AdAware is free to download. Other alternatives are Spybot and Malwarebytes, which also have free and pay versions.

    File-sharing programs are setup by default to share out files that are already on your PC to anyone on the Internet. This could cause you to share out copyrighted material. Companies scan the Internet for machines that are sharing out their copyrighted material. When they find someone on our network sharing copyrighted material, they send a letter to the IT Support Center. Once the IT Support Center is notified they are legally bound to disable the port sharing the copyrighted material.

    You also can get your port disabled if you are allowing too many people to download files from your computer at one time. This could cause excessive bandwidth usage. When this happens, the IT Support Center needs to disable your port to keep the Internet connection open for academic use.

    Attention Windows XP Home Users!

    Please check to make sure you only have one network connection enabled! The home version of Windows XP sometimes tries to use an Internet gateway or a network bridge connection. If you have either of these enabled on your PC under your network connections you could cause problems with the network. If it does cause a network problem your port would be disabled. Here are the steps to disable the extra connections:

    1. Go to the Start menu
    2. Choose Settings
    3. Choose Internet Connections
    4. Look for any connections labeled Bridge or WAN.
    5. Right click on those icons and choose Delete. If delete is grayed out, choose Disable.
    6. If your Internet connection stops working, call us! We can get you back on line.

    Bridged connections can also be a problem in Windows Vista. To remove a bridge from a Vista computer:

    1. Open Network Connections by clicking the Start button, clicking Control Panel, clicking Network and Internet, clicking Network and Sharing Center, and then clicking Manage Network Connections.
    2. Right-click the network bridge that you want to remove, and then click Delete. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
