Hi All

I am having trouble removing what I assume is Malware or a virus. 

I am running Windows 7 Home Premium 64 bit OS.

I have the latest version of McAfee Antivirus Plus and Malwarebytes Anti Malware installed and they both come up saying my system is clean

The windows installer pop up keeps on coming up. I have had a read around and its suggested that I use a regisrty cleaner.

Now I know there are different opinions on whether to use them or not 

I am after some advice on what to do next. Your help will be appreciated.
