Why Antivirus Software Is Needed for PDAs and Mobiles

Most big-name PDAs presently available (HP, Sony, Toshiba, Dell, iPhone and Blackberry) have operating systems as complex as those found only in personal computers not so many years ago. History has shown us that complexity in computing systems is one factor that leads to exploitation by those whose moral values are (ahem) different from most persons’.

Figuring out how spyware invades your privacy

Spyware is a term that applies to a wide variety of features, functions, and bits of software designed for one purpose: to monitor a user’s computing habits and send that data back to a central monitoring site. Spyware uses various methods to track the virtual movements of individuals as they explore the Internet:

Cookies: Some banner-ad companies (the source of those “banner ads” that appear on many Web sites) use these tiny globs of code to identify your individual system and record what Web sites you visit. The idea is to determine which people are seeing which banner ads. This all happens without your clicking a single ad.

ActiveX controls: Some Web sites or banner ads may attempt to download ActiveX controls into your computer.

How to Protect Your Computer with a Firewall

Windows computers can be attacked in many ways — and not just with viruses, worms, or Trojan horses. Another popular way to attack a Windows computer is to attempt to communicate to it over any of the network “ports” found on Windows computers. These ports are kind of like TV channels or radio frequencies. Computers are set up to listen for messages that may arrive from other computers — this is how they communicate with one another.

How firewalls work

Firewalls monitor all the communication between your computer and the Internet. Firewalls know what kinds of communication are allowed to flow in and out. They know this because they have something called an “access control list” — a list of rules that specify precisely what kinds of communications are allowed and what kinds

Deciding How Often to Get Antivirus Updates

Some questions crop up often — “Does my computer have a virus?” “How do I scan for a virus?” “Does Dick Clark wear a toupee?” — But the most-often-asked question about antivirus programs is, “How often should I get updates?” If I was more of a blarney artist, I would attempt to impress you (or bore you) with statistics that would tell you precisely how often to update your virus-signature files. Instead, I’ll provide a shortcut, a simple answer that lays out some practical approaches and why it’s reasonable to use them:

Always-on, broadband Internet connection: If your computer is connected to the Internet all the time, update your signature files at least once or twice each day. If you work with sensitive data that you can’t afford to lose, updating up to six times a day would be better. On a slow news day, this might be construed as overkill, and any more than six times a day would be overkill. But sometimes a really nasty virus is on the loose and multiple variants are popping up every day. If you have to continue your work on a day like this, hunker down and update your signatures every hour or two until the crisis passes.

Real Sikandar-e-Azam (Alexander)

SECOND MUSLIM CALIPH CONQUERED 2.2 MILLION SQ MILES IN 10 YEARS (MORE THAN ALEXANDER (1.7 SQ MILES)

We all think that Alexendar was a great warrior, emperor, but most of us do not know about a person who WAS the greatest ruler in the history of ISLAM, (Hazrat UMER FAROOQ ). I actually read this column about Hazrat Umer Farooq. And I came to know many facts that Hazrat Umer Farooq was the greatest Emperor in this world, not Alexander.
Alexander became king at age of 20, Conquered Greece, Turkey, Iran, Syria, Jerusalem, Babylon, Egypt, India, Then he went back from Sindh (Pakistan).
People Say that he was the greatest EMPORER , WARRIOR or CONQURER. He is known as KING OF KINGS.
But like many other facts about our religion most of all don’t know that HAZRAT UMER was the greatest EMPORER of this world.
