PC Computer Repair - Getting Rid of Spyware by Johnny Mendel

No matter where you go on the web, someone is trying to infiltrate your system. From web sites placing simple logon cookies, to paid advertising tracking your movements on the web, to malicious software that is designed to record your keystrokes and discover passwords, Spyware and Adware have together become a big problem.

Many of these programs are simply dangerous and seriously threaten your online privacy and identity. Even the simple and supposedly benign Adware programs can cause you serious problems.

Spyware is any program that installs itself onto your computer with the intent to spy on your activity. This can be recording your online searching habits, or whatever you type on your keyboard. Adware is not much better. It is designed to watch what you do online, where you go, which terms you search for and then report this to the ad agency that runs the program.

Many, if not most, advertisers on the internet will try and place a cookie or other small program on your computer. Many will add code that will track that cookie as it hits different pages. The code may be designed simply to gather anonymous data, or it may be trying to send ads to your browser that the advertising company thinks you will be more likely to respond to.

Whatever the case, the Adware or Spyware is using your computer to do its tracking. This means that part of your computer's power and CPU cycles are being diverted away from the activity you are trying to perform. Your computer is being used by someone else instead to track your movements. These programs can literally slow your computer down to a crawl, or make it crash altogether. They can fill your computer up with trash files, open unwanted popup windows, use up the space in your internet cache and generally just make working on your computer a nightmare.

Luckily there are several easy solutions to the problem. Spyware and Adware are not the same thing as a computer virus or Trojan Horse. Although a computer virus can install spyware on a computer, you will need different tools to remove a computer virus and to keep your system clean from Spyware and Adware. There are several good Spyware/adware programs on the market. Good programs are Ad-aware from Lavasoft and Spy Sweeper from Webroot Software although there are several others. You can easily find both of these by doing an internet search for Ad-aware and Spy Sweeper or simply do a search for spyware.

DEFCON Badge hacking

By Phillip Torrone

MAKE pal, advisory board member and all around fun hacker guy Joe Grand loads up the details for this year's DEFCON badge hacking contest... via Hackaday. Joe writes -

Well, here we are again! For the 3rd year in a row, I've had the honor of designing the DEFCON badge. And, for the 3rd year in a row, DT has been gracious enough to let me host a contest around hacking the badge. This is the first year that it will be an official contest announced in advance, etc., as previously we've kept the whole thing under wraps until the first day of the con.

Here's a little description of the contest...

The DEFCON Badge Hacking Contest awards the top 3 most ingenious, obscure, mischievous, obscene, or technologically astounding badge modifications created over the weekend. No longer just a boring piece of passive material, the badge is now a full-featured, active electronic product, and it exists for your hacking pleasure.

Computer Network Installation

Computer network installation has become an essential prerequisite for any efficient modern-day business as it allows employees to truly work as a team by sharing information, accessing the same database and staying in touch constantly. For a computer network to give the best results, a lot of detailed planning and foresight is required before installation.

Firstly, an organization needs to clearly define its requirements – how many people would use the network, how many would use it locally (within the office) and how many might require remote access (from a different location), how many computers and other devices (servers, printers, scanners) would be connected to the network, what are the needs of the various departments and who would be in charge of running/managing the network. It also helps if one can anticipate the direction the company would take in the near future so potential growth can be f

actored in during computer network installation.

The technology issues should also be ironed out in advance – hardware, software, servers, switches, back-up devices, cables and network operating systems. Make sure you have the required licenses to run the software on all your machines before installing a computer network. Alongside computer network installation should proceed the building of a dedicated technical support staff, either within your own organization or outside consultants? Delegate responsibility clearly for network management. Before installing the network, you also need to choose the security mechanism to protect corporate data and keep viruses at bay.

The transition to a new or upgraded computer network can bring some teething problems. To minimize chances of confusion, the company might need to train its staff to make them familiar with the new system. Careful planning will to a large extent prevent crises like system downtime and network crashes.
