First Things First Has your computer stopped

Advisor Tool takes the guesswork out of
upgrading. If it has stopped working then before you call out a computer repairer check to make sure that all the power leads are connected correctly and that none of the fuses have blown. If it is still not working then you will need a computer repair call out. Computer or Laptop Just Running Slow? If your computer is just running slowly we advise that you downloaded and run our recommended system repair software if you have not done so already. Invariably we find that many problems are only software related and this will help you avoid paying for uneccessary call out charges. If your computer is only running poorly then there is a fair chance that your problem is software or virus related. Each year people waste hundreds of pounds on computer repair call outs that are really not neccessary and ones that they could easily remedy themselves with the appropriate software. With call out charges ranging between £25-£45, a 2-3 hour repair can easily cost well in excess of £100 which is sometimes more than the computer is actually worth. If it is out of hours, or your computer is just running slow, then we recommend you run your own diagnostics before calling out a professional - you could possibly be saving yourself hundreds of pounds in potential call out charges. System repair tools are inexpensive in this day and age and are designed to be easy to use by both the novice and professional alike, and at less than the cost of a typical initial call out charge this software will not only help get your system back up and running quickly, but will also help keep your computer in tip top condition as long as you have the software installed.

Computer Repair Tips From Computers Repairs UK PC Security - Worm Viruses, Deadliest of All Of the three most common types of malware (malware is short for malicious software, i.e. designed to harm) - viruses, Trojans and worms - the latter is the most harmful because only worms can function without human intervention. Worms, like viruses, replicate themselves but unlike viruses are completely self-contained. Viruses need a 'host program' to spread, but worms propagate independently. Though they can be designed to do the same kind of harm (file deletion, program corruption, etc), worms usually affect networks. Networks operate by means of servers and routers. The Internet is just a large set of mutually cooperating public computer networks. Servers are similar to PC's, though usually faster and with more storage and other resources. They 'serve' other systems by making those resources available to multiple users. Routers are just specialized servers, typically of different hardware and operating systems, used to route network traffic. Hence the name. Worms can be released into a network and their self-replication behavior causes damage. Since routers use memory, processor time, etc worms - like viruses - can overwhelm them, causing them to slow down and become unstable. Viruses don't have to delete files to do harm, they can cause the CPU - central processing unit, used to run programs - to be constantly busy. That leaves no resources for other programs to run. Worms often carry 'payloads' - other types of malware such as spyware or backdoor installation programs. Spyware is used to monitor your computer activities and backdoors are hidden access points to your computer which can be exploited by hackers to send spam or steal data from your computer. The fastest spreading worm ever was 'MyDoom'. First released in January 2004, it was distributed by e-mail and contained the message "andy; I'm just doing my job, nothing personal, sorry." The author was never been discovered, but many believe it was designed to attack software company SCO (Santa Cruz Operation). Programmed to flood SCO's web site with Internet traffic, it quickly spread to the Internet at large causing a world-wide slowdown. For individual computer users, the worm's payload is the biggest threat. Payloads can be designed to work around computer security by turning off antivirus functions or opening up computer ports. Ports are used by network software to move data in and out. Once done, the computer is open to data theft or malicious acts such as deleting files. De-Worming Firewalls are moderately effective in protecting your computer against worms. They can be set up to restrict network traffic and can help to 'cloak' your computer. If your computer can't be 'seen' it can't be infected with worms which spread over networks. However, worms are also distributed in e-mail attachments so use caution when opening mail from unknown recipients or when someone known sends unexpected files. Despite your best precautions, your system may become infected. You may notice your computer acting sluggish or rebooting on its own. Internet access may become very slow. If you suspect your computer is infected with a worm, scan your system with antivirus software. If it fails to remove the worm, instructions for manual removal can be found on the Internet. |
