Which type of malware can infect a system or propagate to other systems?

Malware, being one of the common causes of data breaches, is something every IT and security expert should be concerned about. It’s a fact that many businesses will install anti-virus and forget about it, not knowing that malware can still bypass anti-virus software and firewalls.

The truth is, no anti-virus or anti-malware will protect you from ALL malware. If an infection slips through, it means that your confidential information will be put at risk.

With that being said, it’s important to know the different types of malware and how to prevent them. Keep reading to learn more.

What is malware?

Malware is an umbrella term for any piece of software that has malicious intent. There are several types of malware and each of them has a unique way of infiltrating your computer which may include attempts at gaining unauthorized control of your computer systems, stealing your personal information, encrypting your important files, or causing other harm to your computers. Sometimes the damage can be irrevocable.

Where does malware come from?

Some of the most common sources of malware are email attachments, malicious websites, torrents, and shared networks.

Phishing – Emails can be disguised to be coming from a fraudulent company for the sole purpose of getting you to reveal personal information

Malicious Websites – Some websites may attempt to install malware onto your computer, usually through popups or malicious links

Torrents – Files shared through BitTorrents are generally unsafe because you never know what to expect until they’re downloaded

Shared Networks – A malware-infected computer on the same shared network may spread malware onto your computer

7 Common Types of Malware

Here’s a list of the common types of malware and their malicious intent:

1. Trojans

A Trojan (or Trojan Horse) disguises itself as legitimate software with the purpose of tricking you into executing malicious software on your computer.

2. Spyware

Spyware invades your computer and attempts to steal your personal information such as credit card or banking information, web browsing data, and passwords to various accounts.

3. Adware

Adware is unwanted software that displays advertisements on your screen. Adware collects personal information from you to serve you with more personalized ads.

4. Rootkits

Rootkits enable unauthorized users to gain access to your computer without being detected.

5. Ransomware

Ransomware is designed to encrypt your files and block access to them until a ransom is paid.

6. Worms

A worm replicates itself by infecting other computers that are on the same network. They’re designed to consume bandwidth and interrupt networks.

7. Keyloggers

Keyloggers keep track of your keystrokes on your keyboard and record them on a log. This information is used to gain unauthorized access to your accounts.

How to prevent malware

Be Cautious

A little common sense and caution can also prevent malware from infecting your computer. Here are some tips:

• If an email looks suspicious or too good to be true, don’t open it
• Don’t download files from non-reputable websites as they could contain malicious files
• Don’t use your work laptop on public networks

Additional Tip: Always back up your files!

As mentioned earlier in this article, sometimes malware can cause irrevocable damage — such as file encryption and file loss. To save yourself a lot of trouble, it’s important to keep your files backed up so you can restore them in case something like this happens.
