msi4mahesh, I agree fully that FP's are a pain in the backside that we all can live w/out, but we really need to ensure that is a FP & not a real threat.
I highly recommend you download & run the Emsisoft Emergency Kit & run the Deep Scan. It may look hard to find, but mess with the settings & you'll see it. There will be four blocks displayed, be sure to choose Deep Scan. While there's no such thing as a 100% guarantee of FP's, Emsisoft has won award after award for having a top AV+AM software in Emsisoft Anti Malware, along with having the least FP's.
Here's the 100% Free, no obligation Emsisoft Emergency Kit. It uses no resources unless used, so it's best to keep it installed & when you run it, all it needs is updating to the latest definitions & program, if applicable. Just so happens, we have it on our site.
And in the event it finds & quarantines anything, you may wish to take the 30 day, no obligation, no hassle test drive of Emsisoft Anti Malware to keep your computer clean. It's compatible with most security software & uses little resources to pack such a huge punch. I'm on my 3rd year of running EAM. Just select EAM from under the Home Products column. I included a link below to show you a video what we're all up against today. This is not a sales pitch, it's for real & I'm not an agent for Emsisoft.
Just into my 3rd year of being a happy customer.
