Traits of Scareware
- Providing false messages from anti-virus software – this will trick the users into downloading a fake anti-virus software by informing them their computer has been infected.
- Bombarding your desktop with false-solution pop-ups -these pop-ups often indicate the “problem” and the “solution”.
- Using emails to trick you into downloading malicious files.
