  1. Project By Ben Woodard ISC 110 Professor: Dr. Elaine Wenderholm Anti-Virus Systems

  2. What is a computer virus? • .Small software programs designed to spread from one computer to the next to: .Corrupt/ Delete Data .Hack personal information .Erase information on a hard drive .How do they spread? .Through pop-ups, email attachments, downloads .All computer viruses are a type of Malware .Malware, short for, “Malicious Software” is programmed to disrupt the proper functioning of a private computer, gather sensitive information and more

  3. Types of Malware and how they work • Some of the most common types of Malware include: • Trojan Horses • Computer Worms • “ScareWare” • “ScareWare”: • Alert you of a virus on your computer, convince you to download a program to “clean” the computer • Computer Worms: • Use computer networks, find lapses in program security. Allows them to multiply rapidly • Trojans: • Appear harmless, when downloaded open a “backdoor” through the use of Rookits.

  4. What is an Antivirus System? • .Computer Software designed to protect a private computer from Malware. • There are two main techniques Antivirus Systems use: • Signature Detection • Scanning incoming files and cross referencing the file codes with those of known viruses • Sandbox Security • Scans already running programs and looks for untested/unwanted codes

  5. Other Key Features of Anti-Virus Systems: • Scheduled and On Access Scanning: • Scan downloaded programs on site as well as daily complete system scans • Fire Walls: • Protects users by not allowing unauthorized access to their compuer • Constant Updates: • Relates to Heuristics, most systems have constant updates for new software as well as virus signatures that were not originally in the system • Automatic clean-up: • Anti-Virus systems will stop the infected program, isolate it (depending on system) and quarantine or delete the file/program • Heuristic Scanning: • Detect new “wild type” or modified malware

  6. BitDefender • Romanian Based Company: Softwin. • Original Anti-Virus System Release: November, 2001 • Notable Technologies: • Active Virus Control: • Used when a program is infected. Checks every running program for malicious characteristics • When a threshold of malicious activity is reached in a program, it will be deemed as harmful and treated as malware • B-Have: • Created in 2006, to decrease dependency on virus signatures • Instead, the system looks at the behavior of programs to determine if they are malicious • Uses a virtual computer system to test new programs • If clean the system is allowed to run, if suspected as malware, the system will destroy the file and record its information

  7. Norton Anti-Virus • A Product of Symantec Company • Mostly uses virus signatures with constant program and heuristic updates. • Notable Technologies: • Insight: • The “smart scanning” of programs, where information is sent to Norton to update the system of new malware • Allows for “trusted” programs and files to be looked over in scans thus increasing scan speed • Performed when computer is idle to not interfere with the user • SONAR: • Much like B-Have in that it checks program behaviors, not signatures • Constantly scans running programs using algorithms to find out attributes about the program. Such as, if the program is using shortcuts to gain access to private files • Main goal is to identify any malware instantaneously, known as “zero day” threat detection

  8. AVAST! Anti-virus • Developed by AVAST Software a.s. • Key Features: • Primarily monitors program activities to determine if they are malicious • Has a “Safe-Zone” firewall which helps to go undetected on the internet • Impossible for malware to destroy AVAST! • Sorts corrupted files from safe files and quarantines them known as a “virus chest” • Real time protection as files are downloaded • GMER • Designed to locate and destroy Rookit technology • Rookits enable constant access to a computer to malware or a hacker. They are hard to detect due to the fact that they will die within seemingly safe programs, often times the user has no idea there is a Rookit until it is too late
