If a client's computer has been dropped off at any of the ITS service centers for reasons including virus, spyware, malware and rootkit infections, it is likely that the technicians have installed certain software on your PC.

Here are some instructions on how to config/run these apps

Microsoft Security Essentials - Windows Defender

 To Download Click: Download Microsoft Securty Essentials

Once downloaded simply follow the basic instructions provided by microsoft. If you are running windows 8 or above Windows Defender will already be installed on your computer

Updating Microsoft Security Essentials

It is recommended that you set up the automatic scans to be at a time when your computer is regularly on. If not, you will need to manual run scans on the computer. You will also want to enable automatic update in "Windows Updates" to ensure that this program is regularly up to date.

 Avira AntiVir

  • UPDATE this software daily. To do so, right-click at the Avira icon (red-white color) in the taskbar (bottom-right) and click "Update Antivirus". During the update process, a window might pop-up advertising the various Avira products. Click Ok to ignore it. Once the update has installed itself, you can Close the window or click Report to see details of the process.

  • To open the main screen of AntiVir, click the Avira icon (red-white color) in the taskbar (bottom-right) and click "Free Antivirus".
  • To scan your PC, bring up the main screen of AntiVir. On the left side, click "Scan System" located near the center of the window.

    Partial Scan

    If you do not want to perform a full system scan, other options can be found under the tab "System Scanner"

    Location of Scanner link

  • The scan will run and may take anywhere from 20 minutes to a full hour. A dialog box will appear with the results of the scan allowing you to remove any threats if they were found.


  • Locate CCleaner.exe(or a shortcut to it) and launch the program.
  • The files deleted by CCleaner are usually temporary files stored by various applications. They are of little or no value. However, if you're not comfortable with deleting unknown files, please visit the ITS service centers for assistance.
  • The column at the center of the screen has two tabs: Windows and Applications.
  • Windows: Depending on your system configuration, you should see the following Applications: Internet Explorer, Windows Explorer, System and Advanced.
  • Applications: The applications under this tab vary from PC to PC. The files that are deleted under this tab mainly include shortcuts, temp files and browser history for non-IE browsers.
  • If an ITS technician has installed the program for you, it is likely that all the boxes are checked (Note: If you would like to save the cookies/history for Internet Explorer or leave the Recycle Bin unchanged, feel free to uncheck those boxes.)
  • Click Analyze if you would just like to see details about the files CCleaner can delete. This does NOT perform the deleting process and merely generates a list of files and their details.
  • Click "Run Cleaner" to perform the deletion. Note: Once deleted, these files can't be recovered.

  • To update this software (which is recommended), click "Check for updates..." located at the bottom right of the application window. This will open a link in your default internet browser and will let you know if you are using the latest version of CCleaner. If it isn't, it will provide a link to download the latest version. (Warning: The web page might contain several links and ads to download other applications and software. Please proceed with caution and only download the latest CCleaner version.)


Malwarebytes Anti-Malware

  • Locate mbam.exe(or a shortcut to it) to launch the program.
  • First you should make sure that the databases are up to date. Click update next to the Database Version
  • Select "Scan Now" to begin the malware scan
  • Once the scan is completed, it will display a list of infected items, if any.
  • Select "Remove threats" to remove the infected items


Spybot - Search & Destroy

  • Locate Spybot(or a shortcut to it) to launch the program.
  • Update the definitions right away (recommended!!). To do so, click the "Update" button under the Basic Tools section. It will bring up the updater window.
