Many types of software are designed to send back information to the server computer on a regular basis. This information can vary between internet user patters to system resource usage patterns. Even many popular security software products send such information, which is later populated to develop a better product. But sometimes other malicious software might send out vital information such as your credit card information, SSN, or even bank account number and some other important documents which may be stored in your PC for your personal use.
In spite of advancement in the online security technology, there are many sites that pose various levels of threat to the computers. If you have a proper security system installed in your computer, you will be warned. But many people take this lightly, but without your knowledge your security is compromised.
