The Enemy Within

Protect and Survive. All the weapons in your antivirus arsenal are of no use if you don’t learn to use them properly. 

Back in 1986, a graduate programmer in Lahore, Pakistan wrote a program that copied itself from one floppy disk to another. His name was Amjad Alvi and together with his brother, Basit, he entered computer folklore as the author of Brain, the first computer virus.

Brain is now extinct because it can only infect low density 5.25 inch floppies, which became obsolete long ago, but its descendants now amount to over 200,000 strains and the need for new ways to combat them has spawned an industry worth millions.

Understanding Browser Cache in Internet Explorer

Now that you’re online, all you have to do is learn how to surf with efficient browser settings. This article will help get you started with Internet Explorer.

Your cache plays a crucial role in your Web browsing activities, so it makes sense to understand what it is and how you can use it best

Your cache is a clever creature. It stores the web pages ? text, pictures, sounds, objects ? you visit on the Internet, so that when you revisit the same pages your browser pulls them from its cache instead of hauling them across the Net again.

Overclocking Made Easy

Upgrading your computer doesn’t have to cost you a month’s wages. Want to know how to get a faster PC for free? This article reveals the deepest, darkest secrets of the scary overclocking cult.

Just imagine if the only difference between the two liter sports saloon and the 1.4 family hatchback was the badge on the back. Imagine a car manufacturer that fitted all its cars with the same engine but detuned those in the budget models to protect the price premiums at the top of the range. Imagine if the red line limit on the rev counter was so conservatively marked that you could comfortably exceed it by 50 per cent without damaging the engine.

Creating a Backup Strategy to avoid Disaster

Don’t wait for disaster to strike before you decide to do backups. Take action now to avoid losing all your data when your hard disk crashes.

Organize your data so it is easy to back up. 

You want all your data files (e.g. Word documents, Excel documents, email, etc.) to be in folders that are all inside a single folder on your hard disk. Windows provides you with a folder named “My Documents” designed for this purpose. In Windows 95/98/ME there is a single My Documents folder shared by all users while Windows NT/2000/XP creates a separate My Documents folder for each login account.  Backing up the “WinNTProfiles” folder in NT 4.0 or the “Documents and Settings” folder in Windows 2000/XP will back up the My Documents folders for all users if you are logged in as an administrator.

The Ultimate Security Measures

A hacker views an open screen in the same way a car thief looks at an unattended car with the keys left in the ignition. Always use some form of password protection.

Scare stories. We’ve all heard them and we’ve all passed on a few, especially the tale of hawk-like hackers who can swoop on any data that’s sent across the Internet. If you use the Net, you’re asking for trouble. It’s as simple as that, isn’t it? No!

The Most Important Elements of a Digital Camera

Normally you use a USB cable to transfer pictures from the camera to your computer, which is fine if you don’t have other peripherals competing for a USB port. The alternative is to read the images directly from the memory card. In this article we explore the important elements to look for in a digital camera.

Early digital cameras used to eat batteries as a pre-breakfast snack. Current models are less greedy, but it’s worth choosing a camera that enjoys a varied diet. Some take AA batteries ? rechargeable or otherwise ? while others use proprietary rechargeable battery packs, and most will run off an AC adaptor.
