Sysinternals Antivirus is a malicious and fraudulent scareware program that uses fake Windows Security Center and fake Windows system alerts to warn the gullible users about non-existent malware infections and try to scam money out of the victims.

Once installed this scareware:

  • Creates a fake Windows error message, where the “Fix it” button opens the scanning window of the scareware.
  • Disables administrative tasks like Command prompt, Registry editor and MS configuration editor.
  • Stops software including security programs from being installed.
  • Disables the legitimate Windows Security Center and installs a fake Windows Security Center, where all links opens the scareware windows when clicked.
