Malware is a general term for infected software that attacks a computer and its network. Currently, ransomware is a popular form of malware. Malware can be downloaded to a device in many ways like clicking on suspicious links, downloading and opening documents from unknown sources, or downloading documents from an infected server.
Typically, the attacker wants to find data, but they may be taking over devices to run their attacks in the background. This results in a computer running slowly (because it’s working more than you realize) and losing storage.
Remediation helps to quickly get rid of the infected file, find the extent of the damage, and repair it. The longer it goes undetected, the longer it takes to remediate.
