Malware Infections

Overview

Malware is an umbrella term for malicious software that is intentionally designed to cause damage to a device, disrupt service, or to gain unauthorized access to a device or to data.  Types of Malware include, but are not limited to,  computer viruses, worms, Trojan horses, ransomware, spyware, and adware.

Although technology can play a significant role in protecting your data, remember that the human element of security is often the weakest link in the chain. Many malware infections can be avoided simply by adopting a common-sense, healthy skepticism toward whatever (and whomever) you encounter online.

Tips for avoiding malware infections

Best practices for avoiding malware infection. By following these tips you can siginificantly reduce risk to your computer and private data. 

  • Only open links and downloaded files that you trust completely. If you didn't solicit a download link or a file attachment from someone - even if you know that individual - it should be treated as potentially unsafe. If possible, follow up in person with the sender to verify they, in fact, sent you something. It's possible their account has been compromised and is being used to spread malware. Likewise, avoid sites offering pirated entertainment; these often spread malware through fake files and bogus media player plugins.
  • Install an antivirus program and keep it updated. All NCU-issued computers already have anti-virus installed on them.  These programs will protect your computer full-time and run scans/updates as needed.
    • Personal computers have several options:
      • Windows 8/10 - These operating systems have Windows Defender software built-in. Installing additional AV software is optional
      • Other editions of Windows and MacOS X - Avast and Avira are among the highest-rated free products available.

Potential signs of a malware infection

There are many problems that your device may experience due to being infected with malware.  Below you will find some common symptoms.  

  • Pop-up ads and windows - Often, infected computers will start displaying pop-up messages.  Many even indicate that your computer is infected and to "Click Here" for help.  Do not click on these types of pop-ups as this is usually a scam trying to get you to purchase fake software to clean your computer.
  • Your browser homepage has changed and you did not change it - Many types of malware will either redirect your web browser or set the default web page to a site you are not familiar with.  
  • You get ransom warnings - Cybercriminals that gain access to your computer can hijack your data, encrypt it, and demand a ransom to decrypt it and return it to you.  
  •  Programs that you did not install are on your computer - Sometimes malware will install software on your computer that you are not aware of.  If you notice a new program that you did not install, you may have malware.
  • Sudden or unexpected lack of storage space - There are several types of malware that can manipulate the files saved on your computer. 
  • You're sending out spam - If your colleagues or friends are telling you that you’ve been offering them suspicious messages and links, your device might be compromised.
  • Your anti-virus isn't updating anymore or is unexpectedly disabled - It is common for malware to target the main methods meant at targeting them.
