The internet is full of new content for people to download, enjoy, and share with friends but sometimes those links lead to malware being added to your computers.  

Malware, short for malicious software, is a file or code that can travel through the network and can infect devices. After infecting the devices, it can explore and steal virtually anything an attacker wants. There are multiple forms of malware, including ransomware, viruses, worms, and spyware.  

1. Ransomware encrypts the data from attacked devices and holds the information until the hacker is paid to release it. Hackers will likely set a deadline for payments and threaten to either A.) delete the data or B.) Expose the information they have taken hostage.  
2. Viruses start on one device and spread to others on the network, where they can do damage. This malware can encrypt, corrupt, delete and move your and others’ data.  
3. Worms are similar to viruses, but they do not infect devices. Instead, they go after the known weakness in systems.  
4. Spyware monitors the activities of users. Hackers can log keystrokes users have throughout the day, and the malware gives them access to usernames and more. 

You’re probably thinking “I would never intentionally download a virus,” and you would be right.  

Malware can hide in all sorts of places such as word files, shortcuts created by users, and critical systems files. They can come through emails, servers of common internet files, peer-to-peer sharing, and even file-sharing software.  After it gets in, malware will start to “self-replicate” and eats up a chunk of the device’s memory. Sometimes, depending on the type of malware, it can consume your internet data. These invaders are created to wreak havoc on systems and will destroy applications in the process.  

Do you think you have a form of malware on your device? 

1. Is it taking an abnormally long time to load programs? 
2. Has the device started acting strange? Not being able to do things it usually does. 
3. Are there strange graphics or unusual sounds emitting from the device?  

If you feel like a device has malware the best practice is to quarantine it from other devices, so they do not become infected. Disconnect from any networks they are linked to, and back up files that are not corrupted onto an external hard drive. 

So how do you stay safe from attacks? There are multiple ways to detect and prevent malware on devices.  

1. Keep your devices up to date, both Apple and Microsoft release updates regularly for operating systems. Downloading and installing the updates secures your device with up-to-date systems that improve their security.  
2. Do not download links you are unsure about, especially if they are on a website covered in flashing ads. When online, you should always take caution when visiting websites that seem unsafe.  
3. Do not trust pop-up windows asking you to download software. Close the window and try not to click inside the pop-up.  
4. Use antivirus software for extra protection. It comes in handy when downloading files and checking devices for hidden malware. The best practice is to regularly scan devices to catch any viruses or worms early.
