II. The following are some of the types of computer viruses
File-infecting Virus
A virus that attached itself to an executable program. It is also called a parasitic virus which
typically infects files with .exe or .com extensions. Some file infectors can overwrite host
files and others can damage your hard drive’s formatting.
Macro Virus
This type of virus is commonly found in programs such as Microsoft Word or Excel. These
viruses are usually stored as part of a document and can spread when the files are
transmitted to other computers, often through email attachments.
Browser Hijacker
This virus targets and alters your browser setting. It is often called a browser redirect virus
because it redirects your browser to other malicious websites that you don’t have any
intention of visiting. This virus can pose other threats such as changing the default home
page of your browser.
Web Scripting Virus
A very sneaky virus that targets popular websites. What this virus does is overwrite code
on a website and insert links that can install malicious software on your device. Web
scripting viruses can steal your cookies and use the information to post on your behalf on
the infected website.
Boot Sector Virus
These viruses are once common back when computers are booted from floppy disks.
Today, these viruses are found distributed in forms of physical media such as external
hard drives or USB. If the computer is infected with a boot sector virus, it automatically
loads into the memory enabling control of your computer.
Polymorphic Virus
This virus has the capability to evade anti-virus programs since it can change codes every
time an infected file is performed.
