When worms first appeared, they had no goals other than to proliferate as widely as possible. Early hackers created these worms for their own amusement, to showcase their skills, or to demonstrate holes and vulnerabilities in then-current operating systems. ...
To allow communication between virtual computers, the operating system provides send, receive, and a bounded buffer of messages. 5.1.1.1 Threads The first step in virtualizing a computer is to virtualize the processor. To provide the editor module (shown in Figure 5.3) with a virtual processor,...

In fact, it emerged as soon as the first publicly accessible infrastructures were made available. However, in 1986, most viruses were found in universities and their propagation was...
The risks posed by computer viruses are especially acute for accountants in public practice. Accountants face two threats. First, there is the threat that the accounting firm's computer systems could contract a virus that would result in damage to the firm's programs, data, and/or equipment. ...
