Suspicious.MH690.A keeps popping up every 5 minutes

hello,

first off thanks for any advance and your patience here, totally noob when it comes to computers!!

 

i have NIS2009 installed and tonight i keep getting a message being flagged

 

"Auto-detection has blcoked security risk Suspicious.MH690.A you computer is safe"

 

it does say its been blocked and my PC is secure, but how secure can it be if i keep getting a meesage every 5mins??

 

now upon my limited checking i have found that the file path is alays c:/windows/temp/xxxx (xxx being a different 4 letters, randomly assigned i am guessing)

 

so i deleted all the file in my temp folder, its temp afterall so thought no harm, nothing has gone wrong since i carried that out an hour ago.

but where do i go from here, i did see from some other posts that malwarebytes can be used so i am running a scan with that right now.

 

if theres any other info that is needed i will supply as i want rid of these pigging pop-ups! LOL
