After installing the program, each time the user boots up the computer, they will be greeted with a message nagging them to activate Security Essentials Ultimate Pack, or must otherwise wait 1 minute and 20 seconds, which can be bypassed by using Task Manager to shut down the process, but the nag message will still be there.
After the counter on the message ticks down to 0, it will automatically open Security Essentials Ultimate Pack and run a scan. It will make up a bunch of fake "threats" in an attempt to scare the user into buying the product key and activating it in order to protect his/her computer. Whenever a warning from the rogue appears, it makes a loud and startling pig-squealing noise, which is also found in many other rogue antivirus programs. It will also block certain applications such as regedit.exe, msconfig.exe, and so forth, claiming they are "infected" and cannot be cleaned unless you activate the program.
It will also occasionally make fake reports that their computer is being "attacked" from another machine, and gives a fake IP of the non-existent attacker just to further scare them.
