Computer Maintenance, Part 2: Security

This is not a comprehensive guide to computer security, but a short checklist of things you can do every week or so to avoid most security hazards.

Update your
operating system and applications

Security holes in software are often discovered, so the software developer usually distributes fixes/patches/updates
that address these issues. Virus and spyware scanning software also prompts you to update their definitions to detect more recent threats.

  • Windows: When updates become
    available for Windows or applications, you’ll often receive a prompt
    when starting the application or an icon will appear in the lower-right
    tray.

    • Click the icon and/or follow the instructions on the
      prompt
  • Mac: To check for
    software updates, go to the Apple in the upper left, then select Software Update

Scan for Viruses

UCLA provides Sophos Anti-Virus for free (www.bol.ucla.edu/software/sophos)
and we install it on the computers we issue, so I’ll assume that’s what you’re
using.

  1. Right-click the Sophos shield tray icon (bottom-right
    for Windows, top-right for Mac).
  2. Select Open Sophos Anti-Virus. This will start
    a program that opens a new window.
  3. Click Scan Local Disks (Windows) or click the
    green arrow (Mac).

Scan for Spyware

UCLA provides Webroot Spy Sweeper for free (www.bol.ucla.edu/software/spysweeper).
Windows users should periodically scan for spyware…

  1. Right-click the Spy Sweeper icon in the lower-right tray.
  2. Select Sweep for Spyware. The program will scan your computer for known spyware.
  3. Upon completion, choose to quarantine items discovered.

No virus/spyware (aka malware) scanner detects all threats. To improve your chances of detecting and removing threats, or if you don’t have a virus/spyware scanner installed, try an online malware detection/removal utility.

If you encounter anything puzzling or suspicious, contact me as usual.
