What would you do if you are attacked by computer viruses? Call the computer company to fix your computer, or buy an antivirus software?
I think that either of these two options cost money. Well, not necessarily. You can defend yourself against computer virus attacks without having to spend even a single cent! How so? Keep reading this article to find out.
Any computer user knows how computer viruses work. Malicious code is injected into normal applications and when it runs, it replicates itself by infecting other programs or files on your computer. These codes are written which do stuffs like surfing the Internet without your consent, stealing your personal data illegally, taking up disk space , slowing down your computer performance etcetera.
Malware is computer program that is created to infiltrate people’s computer systems with the only aim of harming or interfering with computer operations.
The biggest threat computer users face today are malware infections, especially rootkits. This kind of infection is designed to hide its presence by intercepting API calls and altering data which results in security breaches without your knowledge. Once installed on your computer system, rooting (or gaining admin) rights allows attackers access to valuable information like passwords, banking details or valuable intellectual property. Some keyloggers may act as botnet agents , allowing an attacker to remotely monitor and control infected computers.
There are so many computer viruses out there which you become a victim of them if you click on suspicious links sent through email or pop up ads from random websites.
The computer world is divided into two major parts: the Windows computer and the Linux computer. There are a few differences between both of them, especially when it comes to computer security.
In a nutshell, Microsoft computer operating system is extremely vulnerable by design due to poor programming practices where as Linux can be considered as totally immune from virus attacks because its currently open-source software means that anyone can go through the code line by line. This has been proved via trial and error by several security researchers across the globe .
Having said that, computer viruses have been developed for attack Linux systems too nowadays since there’s a growing number of users who use this OS as their primary computer platform… But even so , those created viruses will always be detected by computer security experts and taken down to protect computer users.
Well, if you are planning to switch the computer operating system you’re using right now to Linux then I suggest that you stop reading this article at once since it’s going to waste your time (Linux distributions have a different way of doing things). Instead, I’ll explain how computer viruses can be removed from Windows computer which will prove useful for people who give more importance on their personal data saved in their hard disk drives than they do on computer-related stuffs . So in my opinion, the main purpose is FREEDOM rather than CONTROL in computer usage.
Okay so what is a rootkit? This term was coined around September 2004 when researchers found an unknown rootkit on computer systems used in the United States Congress. For them, this was weird since they knew that computer malware can be easily avoided if computer users use Linux instead of Windows.
As mentioned before, computer viruses are program codes which replicate themselves and then alter computer files to perform malicious functions. But rootkits do not need to alter any computer files at all because it already has control over the Operating System . If computer users try to open Task Manager or Registry Editor , these applications will automatically close down because there’s no way for you to remove the rootkit using conventional methods .
But why would someone install a rootkit onto their computer system?
If your computer system is affected by a rootkit, you’ll lose all computer privileges meaning you will only be able to use the computer in ‘safe mode’. This is when computer hackers can gain total access to your computer system because it usually runs in the background without your knowledge.
Rootkits are created by computer hackers who want to do harm or claim their victims’ computer systems as part of a botnet which is basically an army of computers totally controlled by criminals. Other types of malware like keylogger and backdoor trojans are then installed onto this computer system for additional security breaches .
Basically, if you’re using Windows OS , there’s no way that you’ll stop rootkit infections from getting into your computer system because its large attack surface (the entire area where malware can strike) makes it vulnerable against computer viruses .
However, computer hackers can only control your computer if you’re using Windows OS so there is no need for computer malware defense software when you are using Linux.
