However, in both scenarios there must be a cause, such a weak immune system or an expired anti-virus program, in order for the virus to penetrate and spread. Having a reliable anti-virus program is the best solution. Just as a biological virus spreads by injecting its DNA into a host cell, whereas a computer virus needs to attach itself to a document or program to infect other computers and programs. The way a computer virus infiltrates your PC depends on the type of virus it is. Because all computers viruses have their own features and factors that make them unique and dangerous to the health of your computer.

Computer Virus is a kind of malicious software written intentionally to enter a computer without the user’s permission or knowledge, with an ability to replicate itself, thus continuing to spread. Some viruses do little but replicate others can cause severe harm or adversely effect program and performance of the system. A virus should never be assumed harmless and left on a system. Most common types of viruses are mentioned below: Resident Viruses This type of virus is a permanent which dwells in the RAM memory. From there it can overcome and interrupt all of the operations executed by the system: corrupting files and programs that are opened, closed, copied, renamed etc. Examples include: Randex, CMJ, Meve, and MrKlunky. Direct Action Viruses The main purpose of this virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action and infect files in the directory or folder that it is in and in directories that are specified in
