Macro Viruses
In computing terminology, a macro virus is a virus that is written in a macro language: a programming language which is embedded inside a software application (e.g., word processors and spreadsheet applications). Some applications, such as Microsoft Office, Excel, PowerPoint allow macro programs to be embedded in documents such that the macros are run automatically when the document is opened, and this provides a distinct mechanism by which malicious computer instructions can spread. This is one reason it can be dangerous to open unexpected attachments in e-mails. Many antivirus programs can detect macro viruses; however, the macro virus' behavior can still be difficult to detect. Fundamentals A macro is a series of commands and actions that helps automating some tasks - usually a quite short and simple program. However they are created, they need to be executed by some system which interprets the stored commands. Some macro systems are self-contained programs, but othe ...

Victims contact scammers in a variety of ways, often through fake Pop-up ad, pop-ups resembling error messages or via fake "help lines" advertised on websites owned by the scammers. Technical support scammers use Social engineering (security), social engineering and a variety of confidence tricks to persuade their victim of the presence of problems on their computer or mobile device, such as a malware infection, when there are no issues with the victim's device.

Spyware
Spyware (a portmanteau for spying software) is any malware that aims to gather information about a person or organization and send it to another entity in a way that harms the user by violating their privacy, endangering their device's security, or other means. This behavior may be present in other malware and in legitimate software. Websites may engage in spyware behaviors like web tracking. Hardware devices may also be affected. Spyware is frequently associated with advertising and involves many of the same issues. Because these behaviors are so common, and can have non-harmful uses, providing a precise definition of spyware is a difficult task. History As personal computers and broadband connections became more common, the use of the internet for e-commerce transactions rose. Early retailers included book dealer Amazon.com and CD retailer CDNOW.com, which both were founded in 1994. As competition over customers intensified, some e-commerce companies turned to questi ...

However, one high-profile example, the WannaCry worm, traveled automatically between computers without user interaction.
