• • Program Virus - Infects executable files or programs on a computer system. When a user executes an infected program, the virus activates and may replicate itself by embedding its malicious code into other executable files.
• • Multipartite Virus - can infect both executable files and boot sectors. They are capable of spreading through multiple methods, making them particularly resilient and challenging to remove.
• • Stealth Virus - viruses conceal their presence and activities to evade detection by antivirus software.
• • Polymorphic Virus - have the ability to change their code or appearance each time they infect a new file or system, making them more difficult to detect byantivirus software.
• • Macro Virus - are written in macro language and infect documents or templates that support macros, such as those created in Microsoft Word or Excel.
• ActiveX Virus – Because most users do not know how to setup ActiveX and Java controls it leaves a potential security hole
