I recently received a call from an Unknown number. The person was claiming that he was from Windows Technical Team. I don't know from where did he get my phone number and email address.He told me that my computer is affected with Malware and suspicious viruses. He told me to check the following folder in "Computer Management" window: EventViewer->WindowsLogs->Applications.There I see lot of red color errors icon listed and he told me that my personal information is going out of my computer online,like my passwords, documents etc.
