Software, such as a virus or spyware, that has a damaging effect on a computer system. IT is investigating now, but it seems that some evilware has compromised our system.
Software designed to be installed surreptitiously and steal information from the user or inflict harm on their computer. Never download anything from a website unless you are 100% certain it is legitimate—you never know when a site is trying to trick you into downloading malware. The new wave of malware has been locking users' files behind an encrypted password, which they have to pay the authors of the malware to have unlocked.

n. malicious software; software that intentionally harms normal computer software. (Includes viruses, spyware, data miners, trojan horses, and other programs designed to damage or destroy a computer.) The industry is concerned about the increase in “malware” but leaders don’t know what to do at this point. I used all sorts of stuff to get rid of the evilware, but it’s still there somewhere.
