Potential malware - how do I see if it is?

I accidentally clicked on a link for a UPS email that was a scam. When I returned the next day I received a message saying that the copying of my hard drive was halted. A few days later I received a message that my hard drive was in use and had been renamed. Is this a virus or malware? If so how do I scan to see if it is and how do I remove it?

Besides the 2 messages PC is working fine.
