More Than A Virus: Common Malware to Watch Out For

More Than A Virus: Common Malware to Watch Out For

We often use the term “virus” to describe many different types of infection a computer might have. Virus, when used as a blanket term, can describe any number of potential computer programs. Although, these programs have a few things in common: they are designed to cause damage, steal data, or spread across the network.

Malware describes software designed to act maliciously on a personal computer.  The name ‘malware’ is a shorthand for ‘malicious software’ and describes exactly what it is.

A computer virus is a single type of malware that can cause harm to your PC, but it is only one of many. Here are the most common types of malware to watch out for:

Adware is a type of malware that can damage your computer.

Adware

Short for advertising-supported software, adware is a type of malware that delivers advertisements to your computer.  These advertisements are intrusive, irritating, and designed to trick you into clicking something you don’t want.  A common example of malware is pop-up ads that appear on many websites and mobile applications.

Adware often comes bundled with “free” versions of software that uses these intrusive advertising to make up costs.  Additionally, it is commonly installed without the user’s knowledge and made excessively difficult to remove.

Spyware is a type of malware that could infect your computer.

Spyware

Spyware is designed to spy on the user’s activity without their knowledge or consent.  Often installed in the background, spyware can collect keyboard input, harvest data from the computer, monitor web activity, and more.

Spyware typically requires installation to the computer. Victims of spyware are often completely unaware of its presence until it’s too late.

A computer virus is a type of malware.

Virus

A typical virus may install a keylogger to capture passwords, logins, and bank information from the keyboard.  It might steal data, interrupt programs, and cause the computer to crash.

Modern virus programs commonly use your computers processing power and internet bandwidth to perform tasks remotely for hackers.  The first sign of this is when the computer sounds like it is doing a lot of work when no programs should be running.

A computer virus is often spread through phishing emails. Be careful clicking on links or downloading attachments that look suspicious or raise a red flag.

Ransomware is a type of malware.

Ransomware

Ransomware is a particularly malicious variety of malware. It prevents the user from accessing their own files until a ransom is paid. Files within the system are often encrypted with a password that won’t be revealed to the user until payment is received.

One may think a computer worm is a type of virus, but it is actually a type of malware.

Worm

The computer worm is among the most common type of malware.  Worms spread across computer networks by exploiting vulnerabilities within the operating system.  Think of your computer as the host and the computer worm as a parasite. These programs cause harm to their host networks by consuming large amounts of network bandwidth, overloading computers, and using up all of the available resources.

One of the key differences between worms and a regular virus is its ability to make copies of itself and spread independently.  A virus relies on human activity to run a program or open a malicious attachment; worms can simply spread over the network without human intervention.
