• Risks Explained
• Computer Virus
• Affects a computer negatively by altering the way the computer works
• Worm
• copies itself repeatedly, using up resources and possibly shutting down the computer or network
• Trojan Horse
• A malicious program that hides within or looks like a legitimate program
• Rootkit
• Program that hides in a computer and allows someone from a remote location to take full control
• Symptoms
• OS running slow, stops intermittently or does not start
• Less memory available
• Corrupt files and programs
• Programs do not operate properly
• Unknown programs are activated
• Tools
• Hardware firewall
• Software firewall
• Anti-virus
• Virus definition and signature

• Windows update
• Service Packs
• Internet security
• Hardware Firewalls
• Used for blocking access to ports on computers behind a firewall
• Hides the IP address behind a private IP address
• Built into many routers
• In particular, into wireless routers
• Hardware Firewall Brands
• Wireless routers from the following brands have built-in firewalls
• D-Link, Linksys and NetGear
• Software Firewall
• Blocks access to ports on individual computers
• Example:
• Windows Firewall
• Zone Alarm Pro
• Software Firewalls are also built into security suites such as Norton Internet Security and McAfee Internet Security suites

• Likely Source of Viruses
• Email
• This is the most likely source of viruses entering a computer
• Removable disks, or flash disks in general
• Booting with removable disks
• Macros in Programs
• Executing scripts in Web pages
• Forced Execution
• Some website would force the execution of a script
• ctrl-alt-del and ending the task would provide a way out of executing the script
• In some cases, closing the website would be a way out of executing the script
• Preventing attacks
• tips for preventing virus and other malware
• never start a computer with removable media inserted in the drives or plugged in te ports, unless the media are uninfected
• Never open an e-mail attachment unless you are expecting it and it is from a trusted source
• Set the macro security in programs so that you can enable or disable macros. Enable macros only if the document is from a trusted source and you are expecting it 
• Install an antivirus program on all of your computers. update the software and the virus signature files regularly
• scan all downloaded programs for viruses and other malware
• if the antivirus program flags and e-mail attatchment as infected, delete or quarantine the attatchment immediately
• before using any removable media, scan the media for malware/ Follow the procedure even for shrink-wrapped software from major developers. Some commercial software has been infected and distributed to unsuspecting users
• Install a personal firewall program
• stay informed about new virus alerts and virus hoaxes
• Import Considerations in Preventing Attacks
• Avoid booting a computer with a removable media
• disable the execution of macros in office documents such as word and excel documents and outlook emails
