Before Installing VirusScan 8.5—Detailed Instructions

NOTE: If you are installing VirusScan on a departmental computer, please check first with your departmental IT support person.

For best results, there are several steps to take before installing VirusScan:

1. Check for, and uninstall, incompatible software

Look, in particular, for the following:

If you have an IBM ThinkPad or an HP computer. Your computer may have drivers that are incompatible with VirusScan. To resolve this, see our VirusScan 8.5 FAQ.
If you have a SoundBlaster Audigy II card. The "Creative MediaSource Go!" and "Creative RemoteCenter" software may have been installed. This software can cause conflicts with several antivirus products; we recommend that you uninstall "Creative MediaSource Go!" and "Creative RemoteCenter". Contact your vendor or virus.busters@umich.edu if you need assistance.
Adware and Spyware. These can interfere with antivirus software. We recommend that you check for and uninstall all Adware and Spyware before installing VirusScan; see the Adware/Spyware removal section of our Security Recommendations for tools you can use to remove adware and spyware.
Viruses. Some viruses, if they are on your computer before you install VirusScan, can interfere with installation of VirusScan; they may even attack VirusScan before it can be properly installed. If your computer is infected, use Stinger, a free tool available from McAfee, to remove the viruses. Download it from McAfee's Stinger page; it is small enough to fit on a CD (you could also use a USB keychain drive or ZIPdisk, of course). Please download Stinger using a machine that you are sure is uninfected—say, a computer already protected by VirusScan 8.5.
Follow the directions on the Stinger page; in particular, be sure to disable System Restore first if you use Windows XP, and I recommend that you boot in Safe Mode, then run Stinger. If you do not know how to boot in Safe Mode, use Start/Help, then search for Start Windows in Safe Mode and follow the procedure you find there. Alternately, use Google to search for instructions or call 764-HELP.

2. Clear your web browser's cache (optional)

If you'd like to speed the installation process, clear your web browser's cache. This is typically done in your browser's preferences. Check your browser's built-in help (under the Help menu) for details.

3. Download the VirusScan 8.5 installer.

Now you are ready to download the U-M Preconfigured VirusScan 8.5 Installer—again, we recommend downloading it on an uninfected machine. The installer is about 30 MB, so it will take a while to download over a slow modem line. Be sure that your browser has cookies enabled; otherwise the download will fail.

DO NOT attempt to install VirusScan over the web!. You must download it, then save it to your hard drive, and, finally, double-click the installer file to launch the installer.

If you downloaded the VirusScan installer on another computer, copy the installer onto your hard drive.

4. Disconnect from the Internet.

Now, disconnect your computer from the Internet so that it cannot be attacked before VirusScan is installed. You can unplug the Ethernet cable if you are connected directly, or physically turn off the power to your modem.

5. Uninstall any anti-virus software that is currently on your computer.

One last step before installing VirusScan is to uninstall any other anti-virus products you have installed. For most products, this will involve opening the Start menu, then selecting Control Panel, then selecting Add & Remove Software. I recommend restarting your machine after uninstalling any such products.

Note: You need not uninstall anti-Adware/Spyware tools like SpyBot S&D, Ad-Aware, or Windows Defender.
