We wouldn't be surprised to learn if other motivations behind spreading viruses were similar to this person's, but that doesn't justify the damage that viruses do. Innocent people become pawns for the evil plans of others who've convinced themselves they're doing the "right" thing. To protect a computer from getting a virus, or clean a virus from a computer system once infected requires the use of an antivirus utility. avi - This extension indicates a video file playable by most multimedia viewers including Microsoft's Media Player. .bmp - This extension indicates another image file that might have originated from Windows Paint program. .dll - This extension indicates a Dynamic Link Library which may contain additional programming code for software. Although this software does a pretty good job of removing unwanted programs, it can leave some files behind even after a complete uninstall - files which become orphan files. And it's these orphan files that can really clutter up a hard drive and shorten the life of an otherwise, young and robust PC. One of the biggest problems that new computer users have with technical support is not knowing how to correctly describe the problem that they're having. And it isn't fair to expect a tech support person to automatically know what a "thing-a-ma-jingy," or "whatcha-ma-call-it" is. The following describes the correct names for common components of software so that when you experience a problem, you can effectively describe an issue that you're having and a technician can readily resolve it. In an effort to obtain personal information, some spammers will send email that asks you to click on a link. The email messages are often disguised as important messages from well-known online establishments, and they often try to scare their readers into clicking links with threats of closing an account of some sort. And if you haven't jumped onto the binary wagon, you're going to face a few problems. For just as this new lifestyle was once predicted, we're going to predict that "the old ways" will slowly disappear. We're going to predict that all paper-based transactions (checks, money orders, etc.) and documentation (think of the old filing cabinet system) will disappear.
