Almost everything we undertake is fraught with danger. We anticipate the benefits to outweigh the dangers, whether we're driving a car, crossing a busy street, taking a trip to Hawaii, or investing in real estate. Most of us, on the other hand, spend time educating ourselves and devising strategies to improve our chances of success. When we use our computers or other electronic devices to access the internet, the same logic applies. Some dangers may be mitigated with adequate knowledge and upkeep. To put it another way, don't abandon technology. Simply begin to understand how to make good use of it.

What are the symptoms of a computer that is sick or infected?

When... your PC is most likely infected

  • It takes a long time to load, freeze, or crash.
  • Without your knowledge or consent, it sends emails to persons in your contact book.
  • You begin to get a large number of returned, bounced back, or spam emails.
  • Your web browser's home page has been altered without your permission to another site, or you've noticed a weird new toolbar on your browser.
  • When you conduct an online search and land on a completely unrelated website.
  • Unexpected pop-up windows appear on your screen.
  • Your web browser's favorites or bookmarks area contains one or more unwanted new sites.

What makes your computer infected in the first place?

When your computer is linked to the internet, it is in danger of being infected with a variety of malicious software that can degrade its overall performance. The following are the most common forms of infections:

A VIRUS: A computer virus attaches itself to software or file, allowing it to propagate from one machine to another, infecting others along the way. A computer virus, like a human virus, can vary in severity: some may simply cause minor annoyances, while others might harm your hardware, software, or information.

A WORM: A worm is a sub-class of a virus that is designed to be similar to a virus. Worms propagate from computer to computer, but unlike viruses, they may travel without the need for human intervention. A worm makes use of your system's file or information transit capabilities, which allows it to travel independently.

A TROJAN: A Trojan Horse is malware that is specifically intended to steal your personal information. Those who get a Trojan Horse are frequently duped into opening it because it appears like they are receiving authentic software or data from a legitimate source. When a Trojan is installed on your computer, the outcomes might be unpredictable. Some Trojans are meant to be more bothersome than harmful (for example, altering your desktop or adding comical active desktop icons), while others may do real damage to your system by deleting files and destroying data.

Spyware: Spyware infiltrates your computer and "spies" on your activities. It accomplishes this, for example, by tracking the keys you press and thereby encrypting your passwords and other sensitive data.
