Computer Protection


There are several things that you should do to protect your computer from virus infections, spyware and other problems. Follow the tips below to help protect your computer.

Turn on Automatic Updates

When you turn on Automatic Updates, your computer routinely checks the for high-priority updates that can help protect your computer from the latest viruses and other security threats. These updates can include security updates, critical updates, and service packs. Depending on the setting you choose, your computer automatically downloads and installs any high-priority updates that your computer needs, or notifies you as these updates become available. Select your computer's operating system for instructions:

Use Current AntiVirus Software

Antivirus software helps protect your computer from viruses and worms. The worst viruses and worms can make your computer inoperable. Help prevent this by installing an antivirus program. OSU has a site-license for Symantec Antivirus, so all students can install it for free (partially funded by the Technology Resource Fee).

Use Current Anti-Spyware Software

Spyware is often installed without your knowledge when you install other programs and sometimes by just surfing the web. It can be responsible for a wide range of problems including pop-ups, system slow-down, network failure and identity theft.

Turn on a the Firewall

A firewall is a piece of software or hardware that can help protect your computer against network attacks, such as computer viruses. Many operating systems have a software firewall you can activate and most routers have a firewall as well. For instructions to activate your computer's firewall select your computer's operating system:

Do Not Open Files Sent Over Instant Messenger (IM) Programs

Instant messaging, commonly referred to as IM, is a method of online communication like email. The main difference, as the name suggests, is that IM is instantaneous. Using an IM program - such as MSN Messenger, Windows Messenger, AOL Instant Messenger, Yahoo Messenger or others - you and a friend can type messages to each other and see the messages almost immediately.

Never open, accept or download a file in IM from anyone. If the file comes from someone you do know, don't open it unless you know what the file is and you were expecting it. Contact the sender by email, phone, or some other method to confirm that what they sent was not a virus.

Make sure you're using an updated version of your IM software. Using the most up-to-date version of your IM software can better protect your computer against viruses and spyware.

Be Wary of Opening Email Attachments

Many of the most common computer viruses and other malicious software are spread through email attachments (files that are sent along with an email message). If a file attached to an email message contains a virus, it's often launched when you open the file attachment (usually by double-clicking the attachment icon). No matter what email program you use, you can help avoid some viruses by following a few basic rules.

  • Don't open any attachment unless you know whom it's from and you were expecting it.
  • If you receive an email message with an attachment from someone you don't know, delete it immediately.
  • Use antivirus software and keep it updated.
  • If you need to send an email attachment to someone, let them know you'll be sending it so they don't think it's a virus.

Use Strong Passwords

Strong passwords are important because they are the first line of defense against attacks on your computer, but more importantly they protect your identity. Once you've created a good password, keep it secret!

Strong passwords have...
  • 8 characters or more (phrases work well),
  • uppercase & lowercase letters,
  • numbers,
  • non alphanumeric characters (for example, punctuation marks or characters from other language sets)
Strong passwords Do NOT...
  • use your login name in any form (as-is, reversed, capitalized, doubled, etc.).
  • use your first, middle or last name in any form, or your initials or nicknames; or anyone else's.
  • use your spouse's, child's or pet's name.
  • use other information easily obtained about you. This includes license numbers, telephone numbers, social security numbers, the make of your car, the name of the road you live on, the name of your favorite band or sports team etc.
  • use a password of all digits, or of all the same case letter.
  • use a word contained in any dictionary, in any language, spelling lists, or any other list of words or abbreviations.
  • use dates such as September, SEPT2005 or any similar combination.
  • use keyboard sequences, e.g., qwerty.
