computer repair woking Good service computer repair
Does each site computer repair is good? It is not worth to trust advertising and assurances of people who work in them, because often we thus find for dishonest people, who do not provide us with adequate services, and even to damage our equipment. If we want a rapid and professional repair, we should select only the checked sites repairs that have good reviews. The best of these will be branded, well-known places that are known and appreciated for many years, so you might want to look for just such services. If you are not sure where you have the computer, preferably ask your friends or search for information on the Internet.
Laptops - A list of defects
The popularity of laptops is understandable due to their functionality and mobility. Because laptops are smaller than standard computers, iIt is something much more susceptible to damage - if you pour a cup of coffee, the risk of damage to the entire laptop is enormous. If you pour a cup of coffee on a desktop computer keyboard, you have to replace a keyboard - no need extra help. Laptop can accidentally drop it on the floor, it can be thrown off the desk by a cat, or child. Desktops due to their size are less susceptible to mechanical damage. A very important feature of laptops is their portability, which means that it should be fairly light. Behind this, however, it does not go design - lightweight plastic casing is not sufficiently robust. Servicing these devices is much more expensive and not count on the manufacturer's warranty - it does not cover mechanical damage.
Virus - definition:
A computer virus is a malware program that, when executed, replicates by inserting copies of itself (possibly modified) into other computer programs, data files, or the boot sector of the hard drive; when this replication succeeds, the affected areas are then said to be "infected".1234 Viruses often perform some type of harmful activity on infected hosts, such as stealing hard disk space or CPU time, accessing private information, corrupting data, displaying political or humorous messages on the user's screen, spamming their contacts, logging their keystrokes, or even rendering the computer useless. However, not all viruses carry a destructive payload or attempt to hide themselves?the defining characteristic of viruses is that they are self-replicating computer programs which install themselves without user consent.
Virus writers use social engineering and exploit detailed knowledge of security vulnerabilities to gain access to their hosts' computing resources. The vast majority of viruses target systems running Microsoft Windows,567 employing a variety of mechanisms to infect new hosts,8 and often using complex anti-detection/stealth strategies to evade antivirus software.9101112 Motives for creating viruses can include seeking profit, desire to send a political message, personal amusement, to demonstrate that a vulnerability exists in software, for sabotage and denial of service, or simply because they wish to explore artificial life and evolutionary algorithms.13
Computer viruses currently cause billions of dollars' worth of economic damage each year,14 due to causing system failure, wasting computer resources, corrupting data, increasing maintenance costs, etc. In response, free, open-source antivirus tools have been developed, and an industry of antivirus software has cropped up, selling or freely distributing virus protection to users of various operating systems.15 Even though no currently existing antivirus software is able to uncover all computer viruses (especially new ones), computer security researchers are actively searching for new ways to enable antivirus solutions to more effectively detect emerging viruses, before they have already become widely distributed.16
