In addition, it's important to note that macro viruses are cross-platform they can infect both Windows and Mac computers using the same code. These viruses can also be designed to erase or compromise stored data. Some of these viruses cause abnormalities in text documents, such as missing or inserted words, while others access email accounts and send out copies of infected files to all of a user's contacts, who in turn open and access these files because they come from a trusted source. Once an infected macro is run, all other documents on a user's computer become infected. The main risk of macro viruses is their ability to spread quickly. Unlike Trojans, however, macro viruses can replicate themselves and infect other computers. A macro virus is similar to a Trojan virus, since it may appear benign and users may not immediately notice any ill effects.
MACRO FOR MAC COMPUTERS SERIES
They are difficult to detect, as they do not operate until an infected macro is run, at which time they perform a series of commands.
MACRO FOR MAC COMPUTERS CODE
They may come from documents attached to emails, or the code may be downloaded after clicking on "phishing" links in banner ads or URLs. Macro viruses are most commonly found embedded in documents or inserted as malicious code into word-processing programs. The first macro virus, called Concept, appeared in July 1995 and macro viruses (mostly infecting Word documents) subsequently became the dominant type of virus until the turn of the century, when Microsoft disabled macros by default in Office (versions since Office 2000): since then, cybercriminals have had to try and trick their victims into enabling macros before their infected macro is able to run. Macro viruses add their code to the macros associated with documents, spreadsheets and other data files.
