Computer Virus


A computer virus is a program that is designed to copy itself into other programs. When the other programs are run, they carry out the virus’s instructions, either instead of or in addition to their own. Since one of the primary tasks 110 computer virus programmed into a virus is to reproduce itself, a virus program can spread rapidly. Viruses are generally programmed to seek out program files that are likely to be executed in the near future, such as those used by the operating system during the startup process. The result is a copy that can in turn generate an additional copy, and so on. (A virus disguised as an innocuous program is sometimes called a Trojan, short for “Trojan horse.” A distinction is sometimes made between viruses and worms. A worm generally uses flaws in a networking system to send copies to other machines, without needing to insert code into a program.)
Appearing in the 1980s, the first computer viruses were generally spread by infecting programs on floppy disks, which were often passed between users. Today, viruses generally have instructions that enable them to gain access to network facilities (such as e-mail) to facilitate their spreading to other systems on a local network or on the Internet.

OverClocking my Processor Led to Data Loss in Seagate Barracuda

With the extra space that I got and the partitions I created, it was too much fun. I loved to make changes in the BIOS and wherever possible. But, never did I expect that I will face problems after I started trusting it with some sensitive and critical information. Though, I had various options for data recovery services in New Jersey, hardly did I expect that I will have to rely on one.

After just 3 weeks of using it, one fine day, when I started my system installed with Windows XP, abruptly the system stopped responding and I received an error message stating that over-clocking or over voltage may have occurred.

Optimize your Computer

A PC that has not had regular maintenance will slowly grind to a halt and need computer repairs, depending on the mileage you put on it. If you follow the steps outlined here, your PC will run just as good as the day you brought it home from the electronics store.
The first thing to check to begin optimizing your system is the task bar in the lower right hand corner of your desktop display. If you see more than say 10 tasks running, you may be exceeding the capacity of your system’s random access memory. Hold your mouse over the icon, right click, and shut down any tasks you do not need.

All Windows-based PC’s are notorious for storing offline web pages on your machine without you even knowing it. The reason this is done is to speed up your internet surfing and other tasks. Over time, this cache of stored pages can become very large. To delete them, click your Computer icon, then right-click on your hard drive, in most cases this is the C drive. Choose Properties, and then choose Disk Cleanup from the options. This utility will tell you exactly how much space will be cleared by this operation, and if you haven’t performed this operation in a while, it could run quite a while.
