How to Protect Your Computer Against Malware
Malware is any software designed to interfere with a computer or device, display unwanted ads, steal information, change browser settings, spy on activity or gain unauthorized access. Viruses, worms, spyware, keyloggers and other malware all fall into this category. They target Windows computers, macOS devices and even smartphones and tablets.
The first step in protecting against malware is to recognize the warning signs of an infection. If you notice your device running slower than usual, programs crashing frequently or the dreaded Blue Screen of Death, these could be signs that malware is present and consuming system resources. Unusual pop-ups, unfamiliar programs, or strange changes to your computer’s settings can also be a sign of malware.
Other warning signs are unusual network activity, a sudden drop in internet speed or the dreaded ransomware attack. Ransomware is a particularly dangerous form of malware that holds your data hostage and demands money in exchange for the return of it. It’s important to keep your antivirus program up to date to ensure it can protect against the latest threats.
Creating malware is usually done by criminals such as hackers, scammers and swindlers who use the internet to carry out their schemes. However, it can also be done by inexperienced people who wish to show off their newly acquired computer skills (like the infamous “Smashdroid”). The most common type of malware is viruses that can cause damage ranging from data loss to corrupting your entire operating system.
