A quick reminder: Some viruses are destructive and delete (or overwrite) files. You should always have at least two copies of important files saved in two different locations.

To run the antivirus program included on all UDT computers, click Start on the Windows Taskbar, choose Common Programs, then Accessories, followed by Administrative Tools and finally select (click) Virus Scanner from the list of options on the right.

The main window for the Norton AntiVirus Scanner (our UDT "Virus Scanner") is shown below. If you suspect that a virus may be on your U: drive (in your personal storage space labelled "My Stuff"), then select the 'U:' drive by putting a check mark (clicking) in the box to the left of the U: drive. If you would also like to scan your P: drive (your account profiles and desktop) for virus infections then select the 'P:' drive by placing a check mark beside it. Please note: This antivirus scanner will not scan your emails and attachments for viruses. If you suspect an email attachment may contain a virus then you can save it to a file and run the virus scanner before opening the attachment.

If you suspect a virus on the computer you are currently using then select the 'C:' drive in the same manner. (Note: the C: drive is selected by default when Norton Antivirus is started.) You will need to have an administrative computer account to repair many of the files on the C: drive - i.e., you will either need to be a district "Desktop Administrator" (e.g., a Site Contact) or you will need to be logged into a "local administrator" account on that computer.

* * * Please do not scan the R: drive for viruses. * * * The R: drive is read-only and should never be infected.

After you have selected the drives you want to scan press the Scan Now button on the right. Note: You probably do not want to scan the entire S: drive as there are many, many files on the S: drive you do not have permission to repair. See the Timesaver Tip below for instructions on scanning a particular folder.

Timesaver Tip: There may be times when you want to run the antivirus scanner only on a particular folder - such as your folder on the S: drive. You can find the option to scan an individual folder under the Scan menu near the upper left corner of the Norton AntiVirus Scanner window (shown above). First select the drive containing the folder you want to scan in the Drives: section (shown to the right). Next select the folder you want to scan in the Folder: section. You will probably want to scan all files and folders within the folder you've selected so make sure the white box next to Include subfolders contains a checkmark. Then click the Scan button to begin the virus scan.

The virus scanner will begin to search the selected drives (or folder or file) for computer viruses. If it finds a virus, select the Repair button to disinfect - remove the virus from - the file(s).

Unable to Repair? If you discover a virus but are unable to repair it then please let the Site Contact person for your campus know as soon as possible so they can repair the file(s) or submit a Technology Work Request to have the files repaired. In some cases the virus scanner will be unable to repair the infected files in which case they will usually need to be deleted. You should always keep backup copies of important files - in different locations - in case the original files are damaged.

If you have no viruses, the following screen will appear. It means your computer is safe to use... for now.

Remember: The best way to control the spread of computer viruses is to catch them early - before they spread to your other files and to your friends and coworkers. Feel free to use the virus scanner whenever you suspect a virus-related problem or when you receive a suspicious email attachment. It's a good idea to run an antivirus scan periodically to remain confident in the integrity of your data. The more often you exchange files, receive email attachments, download files from the internet, or access shared files on a network, the more often you should scan your files for viruses.

Updates for the virus definition files for Symantec's Norton Antivirus software on DOS and Windows (x86) systems - including our NPS Unified DeskTop (UDT) systems - are included in a self-contained executable update program on the district shared space at:

Definition updates are published by the Symantec Antivirus Research Center (SARC). Their web site, www.sarc.com, is an excellent resource for information about computer viruses and offers the most recent updates to the virus definition files and may be more current than the update on the S: drive. To update the virus definition files for the Norton Antivirus software on your UDT computer you can use the blue "Update Me" button below. During the update process you will be asked a few simple questions:

Question / Message	Response
*IF* you run the update from a link on a web page you will see: What would you like to do with this file? You should select the option to:   Run this program from its current location	OK
You may or may not see a "Security Warning" box appear next which asks: Do you want to install and run "nav_update.exe from S:\district\programs"?	Yes
Do you want to update your virus definition files?	Yes
After updating the files the program will ask: Would you like to search for additional Symantec products containing virus protection?	Yes
The program should find the current virus definition files in the "C:\Program Files\NAVSCAN" folder. Then it will ask you again: Do you want to update the virus definitions files?	Yes
After updating the files the program will ask: Would you like to search for additional Symantec products containing virus protection?	No
Next you will see the "Thank you..." message. (You're finished!)	OK

Happy (and safe) computing!
