Hi, This is a word of warning, you said that you had used an online scanner to check your PC, right?
OK some of those "Free" online services are just out right rip off dogs, and aren't to be trusted.
I accepted one of those "Free" scans from a company called "PEST PATROL", and those dogs flat loaded my system down with all kinds of spy\malware.
Not only did they contaminate my system, but they laughed in my face, and offered to sell me a product for $19.95 US that would remove all of the trash that their free scan had just deposited in my system.
Just something to think about before you let anyone do a free scan on your PC.
