3. How these malware getting to the computer?
Most of the users wonder once they got infection on their computer because they don’t know how they get into the computer even if there is security program installed on the computer. The common reason for this is unsecured browsing and download in appropriate content from the Internet. Misleading applications, sometimes called rogue anti-spyware, trick consumers into believing a problem exists on their system. Consumers who trust the messages are tricked into purchasing bogus applications for resolution of the problems they have been duped into believing exist. Misleading applications scam consumers out of money, faking the existence of problems and failing to deliver the protection they promise. They also create a privacy risk as the victim must provide their credit card information to the scammers in order to register the misleading application and solve the supposed problems. The victims of misleading applications have paid for software that does not work, handed their personal information to scammers, and are left with a false sense of security that leads them to potentially greater risks from more aggressive threats.
