If you own a personal computer today, you should know what the basics of Virus, Spyware and Adware are. They are very dangerous, and can cause severe damage to ones computer or personal information. It can be very frustrating dealing with viruses, spyware and adware, and preventing them on your computer is very important. It is also important to know what they are and what they can do.
A computer virus is basically a harmful computer program, which can modify, delete or steal data and send it to other users to take control of your PC by the Internet. A virus program can embed itself into other programs, and when those programs are executed, the virus is also executed. Then the virus attempts to copy itself into more programs and it spreads like a biological virus. Some viruses may be self-modifying, and as a result make detection more difficult. One common way viruses can enter your computer is by e-mails or downloading sites. Spyware can be similar to a virus, but it can work in different ways that may harm your personal information.
Spyware is computer software that is installed on a personal computer, which transmits the user's information over the Internet, without their knowledge. Some of the names of spyware programs are called spybots or tracking software. How this works is the program secretly collects the information about the user and then relays it to an advertiser or other groups. Installing new programs and pop-ups is how spyware can get into your computer, which may cause your computer to act differently.
Sometimes you may not notice any changes. That is why it is good to scan your computer frequently. Cookies are known to store information about the user, and may be a concern about privacy on the Internet. Some cookies which are stored on your computer from visiting sites may be a risk of spyware on your computer. Adware is the cousin of Spyware, since they have many similar features, but few differences.
Adware is a software application that is mainly used as a Marketing tool to monitor people's interest, so that they can determine which products they are interested in. Adware supposedly does not report statistics to it's creator but spyware does. Adware may be displayed as an undesired banner, ads or pop-up windows with ads, and sometimes contain a carrier of spyware and viruses called "Trojan Horses", which may be difficult to get rid of. Typically, adware can be a type of spyware that collects information and data about the user, which passes it on to other parties, without the user's knowledge. Other adware programs enter your system through the browser, and some web sites may abuse security holes to install adware on your system. That is why a good removal program is crucial.
There are many anti-virus and anti-spyware programs that do the job. Unfortunately, not all current branded virus software will pick up every spyware, adware or virus, so it is wise to have more than one scanner. Finding a program that can remove viruses, spyware, and adware are essential. If you would like to know which software is the best for each category, you can visit my blog.
