Security ALert

For the past 2 days I keep receiving a security alert That says: Potential threat details We detected potential threats that might compromise your privacy or damage your computer. Your access to these items may be suspended until you take an action. Detected Items Alert Level Recommendation Status Malware:Win32/Caphaw Severe Remove Active Search for a Solution I have tried all the name brand virus/malware software and They did not recognize the name. When I clicked on search for a solution, it did not find one and said it had to be removed manually. That would be great except I haven't found it doing a cox, google, Microsoft or bing search. Does anyone have any other suggestions. I'm using windows 8.1 (yuck) as my OS.
