That type of site is trying to get people to install malware, they are typically aimed at Windows users. The alerts are typically bogus and it will appear to scan your computer and show some infections. Those scans will look like a Windows scan even though you are on a Mac.

To ensure you are clean try running a full scan with your anti-virus program.
