Security Defense is a security application that, in all aspect is not capable of protecting the computer against viruses. Therefore, it is rogue software. Security Defense is so aggressive that it can break into someone’s PC in a variety of ways. To fulfill its very own objective of ruling the system, it pushes infection into Windows registry and adds some changes. Technically, this process makes things uncomplicated for the rogue program to control the operation of your machine as system runs. It will be impossible to track virus’ moves specifically if antivirus is disabled. Many other malicious files are set to be fetch from different servers that will help expand the damages Security Defense can cause.
All of the mentioned anomalies may occur when visiting infected web sites. Downloading files from file-sharing networks is a contributing factor to the spread of Security Defense. Unconsciously, opening emails and links from instant messages programs can also lead to virus infection.
If Security Defense has succeeded in getting inside the computer, you’ll begin to realize of its destructive force when all programs are kept unusable. Certainly, Security Defense will not admit its offense. Instead it will disguise as legitimate anti-virus program and start to notify you that all programs are infected with virus. The fake AV suddenly suggests doing a complete clean-up by using the registered version of Security Defense. As you can notice, what it does was to intelligently promote a useless product. Don’t buy Security Defense and save your money for an effective security product that you may need to protect your PC against incoming attack.
