BlockKeeper is a rogue antispyware program that installed from fake “free online scanner” that displays that your PC is infected with a lot of trojans and that you must install the software to clean your computer. The software is trojan. Once downloaded and run, it will download and install BlockKeeper on to your PC. Also this trojan will create numerous files with random names that are made to appear as infections, but are in reality harmless.
Once BlockKeeper is installed, it will register itself in the Windows registry to run automatically every time, when you start your computer. Once running, BlockKeeper will begin to scan the computer and list previously created files as infections to trick you to buy the paid version of the software. All of these infections are fake, so you can safely ignore them.

The same trojan that installs BlockKeeper will also install a trojan that displays fake Windows Security Center, nag screens, fake security alerts, notifications from Windows task bar and other pop-ups. An example:
Spyware Alert!
Your computer is infected with spyware. It could damage your
critical files or expose your private data on the Internet. Click
here to register your copy of BlockKeeper and remove
spyware threats from your PC.
Just like scan false results, these alerts and warnings are all fake and should be ignored. As you can see, the program is designed only for one to trick you into buying the software.
