Terminates or blocks programs
Some Win32/FakeSysdef variants that may terminate running processes during installation and may block launched application after the computer restarts. During the installation process, they may terminate all running processes and force the computer to restart.

After the restart, FakeSysdef attempts to block every launched program, and may then display fake error messages offering to fix the problem. It then repeatedly restarts the computer until the user agrees to buy the fake software.
