How Malware Can Infect Your Computer?

Malware is a code or file, normally delivered over a network, that infects, steals, or conducts any type of behavior that an attacker wants virtually. Since malware comes in many forms, there are a number of methods that infect computer systems. It is important to portect your devices and data from malware. 

Types of Malware

Once you have identified the type of malware that has infected your computer, it is essential that you choose the best protection from malware.

Spam Emails

Malware authors may trick you into downloading malicious files, such as an email containing a file telling you it is a receipt for delivery, invoice, or a tax refund. It may tell you that you must open the attachment in order to receive the items or get money. If you do open the attachment, you will end up installing malware on your computer.

These emails are often easy to notice, such as bad spelling and grammar, or they may be sent from an unrecognized email address.

Malicious Office Macros

This consists of a powerful scripting language that enables the developers to design tools to help you be more productive. Unfortunately, many criminals can also use that same scripting language to design malicious scripts that install malware on your PC.

Infected Removable Drives

Many works infect removable drives such as USB flash drives or external hard drives and end up spreading. The malware may install automatically on your PC once you connect the infected drive to your computer. However, if you don’t plug it in, you can’t get infected.

Always be wary of any USB device that is not yours. If you happen to find a USB device that was discarded or lost, don’t be so quick to plug it into a computer with data you care about. Often, attackers will leave infected USB devices lying around in popular areas, deliberately hoping that someone will find them and plug them into their PC.

Bundled With Other Software

Many times, malware can even be installed at the same time as other programs you download on to your PC, including software from third-party websites. These can even come from files that have been shared via peer-to-peer networks. To avoid installing malware or unwanted software, make sure that you always download software from the official vendor’s website. Additionally, you should ensure that you read what you are installing.

Compromised or Hacked Webpages

Malware can also consist of software vulnerabilities that can infect your computer. For example, when you go to a website, it may try to use vulnerabilities in your web browser to infect your computer with malware. The site may be legitimate but has been hacked, or the site may just be malicious. This is why it is important to keep your software up to date. Any software that you don’t use should be removed.

Other Malware

Other types of malware can download other threats to your computer, and once they have been installed, they will continuously download more threats.
