While surfing suddenly a window appears saying your computer is at risk.. "Install Antimalware Doctor AntiVirus" which is eventually a Virus. I scanned my whole system with McAfee antiVirus it did not detect any Virus in my system which cannot be accepted. McAfee is one of the trusted Anti Virus Software available in the market currently but didnt expect this. Can anyone help me in this regards..
Thanks in Advance.
Please run the Stinger tool to remove virus
