In addition I receive a virus alert saying computer is now infected and I need to buy someone's PC security tools to remove.Has anyone has this problem and how can I remove?Thank you.1 person needs an answerI do too

Hi, Your system seems to be infected by malicious software which is not removed from your system even though you have run the Microsoft security essentials. I would suggest you to run theMalicious Software Removal Tool on the system.Malicious Software Removal Toolhttp://www.microsoft.com/security/malwareremove/default.aspxI would also suggest you to run the online scan on the system and check. Check the link mentioned below.http://onecare.live.com/ Thank you and Regards.
