Viruses
Viruses are user-initiated, replicating, and malicious pieces of code that attach themselves to an existing program and can have a serious effect on your operating system, files, and even your antivirus' ability to work properly. The most obvious sign that you've been hit by a virus is the lackluster performance of your system. Viruses are constantly changing as the technology to block them does, making them a constant threat for individuals and businesses alike. Most viruses attack a specific part of your system for which they were written. Types of viruses include:- Bootsector Virus: A virus that is designed to attach itself to the hard disk at the point where the computer initially reads upon startup.
- Macro Virus: A virus that is designed to use an application's macro programming language to dispense itself. They target and affect documents and eventually infect related files.
- Memory Resilient Virus: A virus that targets the computer's memory (RAM).
- Polymorphic Virus: This virus not only replicates itself, it varies its digital signature when it does, making it tough for less-refined antivirus programs to target.
- Rootkit Virus: A virus that is designed to give a third-party administrative control over a system. They are usually disguised as system files.
