Norton Free Anti-Virus Scan re-pop-up after removal.

Recently I tried to do a Norton Free Anti-Virus Scan on my computer. I downloaded the installer from below URL:-

https://security.symantec.com/nss/getnss.aspx?langid=ie&venid=sym

I executed the installer, but the installer got sort of hanged. It was like taking forever in 'Configuring anti-virus scan' stage. So, I ended the process through task manager and I restarted the PC.

But after I restarted the PC, I could see this program on my Programs and Features list. I tried to uninstall it from there but failed, so, I deleted the respective folder from Program Files*86. I then uninstalled it through CCleaner, too. Then I restarted the PC.

After that, I, out of nowhere, find the same Norton setup being executed. This happens not too frequently, but I suppose once every start-shut down session(not immediately after starting). I have attached the relevant screenshot.

It seems some kind of virus. But its hard to believe. I mean, its Norton after all.

Update:- I tried contacting Norton support and the support exec. executed some kind of Norton Software Removal Setup and restarted. He thought that the problem has been fixed but I received the pop-up again!
