The bottom line: to keep your data safe and your computer productive, follow these signs for safe computing.

	Use effective passwords. Prevent identity theft with these "strong" password tips. Don't share passwords — you risk exposing your email, class registration, grades and salary/wages information.
	Install antivirus software. Get antivirus software for your computer. Marquette maintains a campus site license for McAfee antivirus software available to students, faculty and staff.
	Keep your system up to date. Set up Windows to check for system updates automatically. New updates to your system come out regularly to patch vulnerabilities. Mac users: Use Software Update.
	Be vigilant for hoax emails. Know what phishing emails are(PDF). Don't fall for the email asking you to enter your credit card number or bank information.
	Scan for spyware. Protect your privacy online; download AdAware to remove spyware. A second tool to run: Spybot Search and Destroy. Spyware can sneak into your computer (often when you install freeware) and track your every move.
	Reduce the amount of spam you recive in your eMarq/Outlook Inbox. Activate spam filtering at the level of your choice.
	Put up a firewall. Enable a firewall for Windows XP (or turn on a Mac OS X firewall.). Firewalls keep intruders out of your computer.
	Keep an eye on your computer and logout. Do not leave your computer unattended. Always logout before leaving a lab/library computer. Guard access to your computer by keeping it in a locked room or buy a lock from CDWG to keep your computer from walking away.
	Uninstall file sharing programs. File sharing slows network performance and puts your computer at risk to receive malicious programs. Besides the danger to your computer, Marquette prohibits the illegal download and distribution of copyrighted materials.
	Ensure personal and university data stays private. Remove Hidden Data from Microsoft Documents
