Welcome to the Virus Encyclopedia of Panda Security.
Jerk.A is a polymorphic, macro virus that infects Word documents, as well as Excel spreadsheets.
Jerk.A uses the normal means of infection used by macro viruses. Firstly, it infects Word's global template and Excel templates and then, it will infect all the Word documents and Excel spreadsheets that are opened, closed or saved in the affected computer.
Word documents (files with a DOC extension) get infected when the user closes them, whereas Excel spreadsheets (files with an XLS extension) are infected when one of their objects loses focus.
Jerk.A activates on the fourteenth of any month between June and December, both inclusive. It disables macro antivirus protection and displays a message on screen.
Jerk.A is easy to recognize once it has infected a computer, as it displays a dialog box on screen on the fourteenth of any month between June and December, both inclusive.
Instead of Unknown, Jerk.A displays the name of the infected user, copied from the Properties tab of the document.
