When computer long time nobody use, such as the worker goes home, the virus receive an additional executable code from the Internet, which examine your hard drives data and send information to your web site. If someone touch mouse or keyboard, virus stops working in order to remain unnoticed and waits another occasion.
Virus hunters last June found very similar infection, which acts with screen saver Prety-Park.exe. This be sent as an attachment to an e-mail message. When installed “mIRC” it sends user login and password information, with outgoing messages.
