I recently made a support call to what I thought was HP customer support. The rep that answered tried to convince me I had a virus in my hard drive and that I needed to purchase Microsoft Forefront Security Service. At this point I ended the call, however I did foolishly allow the rep to access my computer using logmein123. I then found out I had called 247help-desk.us, which seems pretty shady. I am currently running antivirus and anti malware on the computer while in safe mode. Are there any other precautions I should take, or am I overreacting as it is?
