Keep in mind that neither Microsoft nor its partners call you for your computer security issues. Such types of calls are phishing scams. The motive of these calls is to steal the confidential data from the user’s computer so that they could use it for blackmailing purposes. The person on call may also ask to access your computer by installing a particular software. If you grant him/her to access your computer, he/she may execute a malicious code on your system or completely lock your computer. After that, the hacker will ask you for a certain amount of money to unlock your computer.
