A new scam currently turning up involves people receiving a telephone call from someone purporting to be from Microsoft and that there is a dangerous computer virus infecting the Windows operating system on the person’s computer. The caller then asks the person to log on to their computer and go through with the scammer the steps necessary to clear the computer of the threat. The threat, of course, comes from the caller who uses the call to gather personal information to turn the person receiving the call into a victim of identity theft.
Microsoft would not call you. Never give personal information over the phone to someone you have not called or are not completely sure who they are. As for your Windows software, make sure it is always up to date. Automatic regular updating is best. Also make sure that you have legitimate security software on your computer and up to date to protect you from viruses, spyware and malware.
