Virus Prevention for Office Computers

There are two vital steps to ensure your Office PC is protected from viruses and worms.

Sophos software and updates

Sophos is set up to check for and download updates whenever your computer is on the Internet. By default, the program will search for updates every 60 minutes. If the update fails for some reason, you will see a little red x over the shield in the system tray—double click on the shield and it will attempt to download the updates again. If you want to change the automatic settings, do the following:

  1. Open Sophos by right-clicking the blue shield in the system tray (by the clock) and selecting Open Sophos Anti-Virus. Alternatively, click Start > All Programs > Sophos > Sophos Anti-Virus.
  2. When Sophos opens, click on Configure Sophos Anti-Virus in the main screen.
  3. At the bottom of the page, click on Update options.
  4. Navigate to the Schedule tab and adjust the frequency at which Sophos checks for updates. Click OK to save your settings.

Scanning your computer with Sophos Anti-Virus

  1. It is good practice to scan your computer for viruses at least once a week. Follow these steps to scan your computer with Sophos:
    Open Sophos by right-clicking the blue shield in the system tray (by the clock) and selecting Open Sophos Anti-Virus. Alternatively, click Start > All Programs > Sophos > Sophos Anti-Virus.
  2. When Sophos opens, click on Scan my computer.
  3. A new window will open displaying the scan's progress. When Sophos detects a problem it is automatically moved to the Quarantine.
  4. When the scan is complete, close the small scan window.

When the scan is finished, be sure to go into the Quarantine and delete any viruses and spyware picked up by the scan.

  1. With Sophos open, click on Manage quarantine items in the main screen.
  2. You will see a list of items detected by the scan. Scroll to the right side of the window and click delete next to each virus or spyware item.
  3. Occasionally Sophos requires that your computer is restarted, and sometimes rescanned, to fully remove a particularly bad virus. If prompted to restart or rescan your computer, do so to make sure that everything malicious is completely removed.

Note: the procedure above scans select, high risk files on your computer, not the whole thing. For the most part, this simple scan is sufficient; however, if you have reason to believe that your computer has a serious infection, follow these steps to create a full system scan.

  1. With Sophos open, click Set up a new scan.
  2. Enter a name for your new scan in the Scan Name: box.
  3. You can choose which locations on your computer you want to scan. To scan the whole computer, simply check the box next to My Computer—all the other boxes (except My Network Places) will automatically be checked as well.
  4. At the bottom of the window, click Configure this scan.
  5. Under the Options tab, select Scan all files. Click OK to save your settings.
  6. If you want your new scan to run on a schedule (i.e. every Monday at 3:00 pm), click on Schedule this scan at the bottom of the window.
  7. Check the box next to Enable schedule then select the day(s) and time(s) you want your scan to run. It is often convenient to schedule scans to run at a time when you won't be using your computer—this way it won't interfere with your work. Click OK to save your settings.
  8. If you want the scan to run right now, click the Save and start button. If you would like to wait and scan your computer later, just click Save.
  9. When you want to use your scan again, just open Sophos and find the scan you want to run under Available Scans.

MS Windows Updates

Office computers are configured to check and download critical windows system updates when they are available.

If your computer is on, the updates will be downloaded at 2:00 a.m. and since auto restarting is not turned on, the updates will be installed the next time your computer is turned on.

If your computer is turned off when the critical updates are scheduled to be downloaded, the updates will download after you turn your system on and since auto restarting is not turned on, the updates will be installed the next time your computer is turned on. Please restart your computer for the updates to be effective.

Please note that to receive the scheduled critical updates every week, you must login to the campus domain.

Note: If you receive a warning message from Sophos AntiVirus that a virus is quarantined or cannot be removed from your system, please contact the Help Desk at x1112 immediately.
