Microsoft Says I Am Infected

 I was on the internet and went to a website to read an article. All of the sudden this message comes up supposedly from Microsoft saying I am infected and I should call this number. DO NOT CALL THEM IT IS A SCAM. I have had quite a few customers that called them and wanted them to pay a certain fee for protection and to clean their system. This is simply not true as Microsoft does not call people.
 Okay so what should you do if this happens ? Well first don't call them. Next do not click anything to close out there garbage. If you do it may trigger their infection and it can do all kinds of damage to your software. I had one customer where they changed the user name and put a fake start up password. There is no way to remove this from your system. The only choice is to save your data, reformat your hard drive and reinstall all your software, then move the data back in place. It can be very costly if done by a certified computer service center.
 So basically hold the power button in for 10 to 20 seconds and the computer should shut off. If you are going to check your system I would use some programs like, rogue killer, Free Malwarebytes, Junkware Removal Tool, ADW Cleaner and Combox on windows 7 or 8. The best way is to enter the Safemode With Networking. Run each and reboot when necessary. Once back in the normal mode check programs and features in the control panel to look for anything that was installed at about the date this happened.
 If the virus installed the start password, then your only choice is to save any data, reformat and reinstall windows. Then reinstall all your software programs as well as printers. Just remember to save your data first. You can save your data to an external hard drive using something like hirens repair disk with programs on it like unstoppable copier.
