How computer viruses are spread.

computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the owner. The term “virus” is also used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer. The term “computer virus” is sometimes used as a catch-all phrase to include all types of malware. Malware includes computer viruses, worms, trojan horses, most rootkits, spyware, dishonest adware, crimeware, and other malicious and unwanted software), including true viruses. Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a program that appears harmless but has a hidden agenda. Worms and Trojans, like viruses, may cause harm to either a computer system’s hosted data, functional performance, or networking throughput, when they are executed. Some viruses and other […]

Windows XP Shut Down and Automatic Reboot/Restarts Problems

This topic was prompted by a problem that one of our clients was facing. He ran into a problem trying to get his computer to shut down: He was running Windows XP Professional and it absolutely refused to shut down. Every time he tried to shut down it could go through the motions, but when it got to the point to turn off the machine, the BIOS screen could come up and the machine reboots. Annoying; well let’s look at the causes before we tell you what worked for our Client. There are three basic sources of automatic reboot problems: Recovery settings Software incompatibilities, including driver issues BIOS problems Recovery Settings One of the things that is quite different about Windows XP compared to Windows 9x (9x is shorthand for Windows 95, Windows 98, and Windows Me in all their various versions), is that one can control how it responds to certain critical errors—those that cause the infamous Blue Screen of Death (BSOD). In Windows XP, the default setting is for the computer to reboot automatically when a fatal error occurs. If that fatal error only occurs when you’re shutting down, the system reboots automatically. If you haven’t changed any of the system failure settings, you should be able to see the error by looking in the Event Log. But a better long-term solution is to turn off the automatic reboot so you can actually see the error when it happens—chances are it will tell you enough about itself to let you troubleshoot further. To change the recovery settings to disable automatic rebooting: Right-click […]
