Have you ever wondered if there might be spyware or viruses on your computer that you are unaware of? How could you find this out? How does your computer become infected in the first place? There are various ways that this can happen.
A computer virus spreads, when a user clicks on a contaminated file: “Master boot record, auto-run script or MS Office macro.” The virus can spread from file to file but also from one PC to another. Some viruses will lock up your computer, while others attack individual files, either contaminating or completely removing them.
Trojans are not viruses. They do not multiply! They can be added to your computer by the same methods viruses are obtained. What a Trojan can do is to turn it into a spam-delivering machine, make it into a server that sends out malware to other computers or block users from access to certain websites. Antivirus protection also can protect you from Trojans, but this protection must be requested and isn’t included in every plan.
By visiting certain websites, Spyware can be added to your computer. Spyware works by tracking users, who log into websites, paying particular attention to personal information that can be used to make purchases. Additionally, new search engines may be added to your home page. Your buying patterns may be observed so that marketers can learn how to better market products to you. Some spyware is strictly marketing focused, while other spyware is used by identity thieves, who have every intent of using your personal/financial information for their own devious means.
Antivirus protection in disguise is known as Scareware. This will appear as a pop-up message, telling you to install said antivirus protection. Then, another pop-up message tells you that you have been infected with a mass quantity of viruses. To rid yourself of this problem, a user is told to simply purchase said antivirus protection.
For information on how to remove scareware and other various types of malware, visit http://lifehacker.com/5560443/whats-the-difference-between-viruses-trojans-worms-and-other-malware. It’s always a good practice to NOT click on unfamiliar URLs or open attachments from unfamiliar persons/businesses, when going through your email. Be skeptical about pop-up messages. An unknowing, trusting click can get you, your PC, and any personal information (passwords included) compromised and in a lot of trouble ahead.
