Malware, or malicious software, is any program or file that is created to intentionally bring harm to a computer, network, or computer server. Types of malware include computer viruses, worms, Trojan horses, ransomware, and spyware. These are used to steal passwords, gain access to secured information, demand a ransom for the release of files, and delete corporate files to damage a company significantly. If you don't have a trusted IT guy like Joshua Shuemake, you could find yourself without your vital files to run your business.
