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, 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

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.

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

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

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

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

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
