Unlocker is a Windows feature that allows your computer to lock the hard drive in such a way that you will not be able to reformat the hard drive without the help of a special tool. Windows requires the software to be run before it can use it to do its job. However, the anti-spyware program can also be used by the user without the software. If you were to purchase the software, you would need to unlock the computer before you could reformat the computer or copy any important files. This process will take you time because you would have to remove the spyware from the computer and then remove the applications that have been infected by the spyware. The other thing that you would have to do is to erase the stored files to make room for the new ones.
Unlocker is available in free versions and the paid versions. The free version is not worth the download price because it is not reliable or powerful enough to perform all the functions that the Windows system needs. Some free versions only contain key-logging features. Other free versions do not function properly and some even cause problems when they install themselves to the computer. The paid versions are usually used for more complicated functions and for ensuring that the computer will not lock into any settings unless the user unlocks the computer manually.
Unlocker is a popular application in the market, but there are still some people who prefer to use free versions. Some software reviews have concluded that the free versions offer limited functionality, and the application is unable to do many of the things that it was meant to do. Unlocker will have no effect on your computer if you use free versions.
