What is Malware and How Can it Affect You?
Malware is hostile software that aims to invade, damage or disable computers, computer systems, networks, tablets, mobile devices and even the Internet of Things (IoT) when users and IT security are least prepared. The motives vary wildly, but malware can steal or encrypt data, lock up systems for ransom, spy on device activity and more.
There are many types of malware threats, ranging from viruses to worms, Trojan horses, spyware and some forms of adware. The term “malware” is generally used to refer to software or firmware intended to perform an unauthorized process with adverse impact on the confidentiality, integrity, or availability of the host system, but it can also be applied to any code-based entity that infects the host.
Signs that a computer may be infected with malware include: A loss of disk space. An overworked system that takes a long time to respond to commands. An unusual swell in network traffic that correlates with your browsing behavior. A new toolbar, extension or home page that has been added without your consent.
If you think you may have been infected with malware, the best thing to do is unplug the device from the network and power it down. This will stop it from communicating with its control server and sending stolen information. It is also a good idea to restart in Safe Mode, which will load only essential services and make it easier to find the malware and remove it. Once everything is cleared up, be sure to set up scans and updates in Windows to prevent future infections.
