Howt can I do to protect myself from computer viruses and Trojans?
In this Days everyone's online, downloading and exchanging files, a If you're not careful, your computer can end up with a nasty virus that makes your files act oddly, crashes your computer, pops up bizarre messages, or worst of all, destroys your operating system. A computer virus is the most subtle of computer problems. It usually loads itself into your computer system when you run a program to which it has attached itself.and the computer system, it'll then reproduce itself, much like a biological virus would, by attaching copies of itself to other programs on your hard drive. What it does then depends on the malevolence of its creator. Some viruses are nothing more than a practical joke. They may bring up a message like "Merry Xmas" or melt your display. Most of them though, either start destroying your system or your files immediately or on a date specified by their creators—like the much-publicized Michelangelo virus, which erases important pieces of your system on March 6. "Trojan horse" programs are similar to viruses in their effect on your system, but they can't reproduce themselves.

But when you run the new program you just found, it can do anything from popping up a message to erasing your hard disk, as the rogue PKZIP utility really did.

Protect Yourself
- Always use an anti-virus software program, one with both an on-demand and an on-access scanner. You'll want to look for one that has a fairly complete database of viruses and that is updateable. New viruses are produced daily, so it's important to have software that can detect the latest threat.
- Update the virus database in your anti-virus program regularly
- Don't allow your web browser to automatically run programs, such as MS Word or other programs through its e-mail program. Configure your browser to launch WordPad or Notepad instead. One of the biggest and growing threats is the macro virus, which is spread through data processing and spread sheet programs
- Configure your web browsers to disable ActiveX, Java, and Javascript. You'll lose some of the fun the Web's been known for, but you'll save your computer from contracting a virus and speed up your connection
- .Using an updated anti-virus program, scan all new software for viruses before installing them on your hard drive. Even shrink-wrapped software from major publishers has been known to contain viruses.
- surfing the internet avoid websites that contain illegal software downloads, sexual references, free screensavers, cracks or serials, etc. I am sure you get the picture. If you go near these sites you are immediately asking for trouble. Some other websites that you should stay away from include foreign websites where you cannot understand the language on them. This is because you cannot tell what is on the website
- change your email settings and receive text emails only. You can also disable the ability to open email attachments. Virus travel in HTML enabled emails and file attachments. They cannot travel in text email messages.
- Firewall enabled on your computer. Windows comes with an inbuilt firewall or you can use a third party firewall program like Zone Alarm. Either way, make sure the firewall is on…To check the Windows Firewall go to the security settings in your control panel.
