Have I got a virus?

I did a boot time scan on my computer today and 6 files had an error. What is this error? Do I have a virus on my computer? I have uploaded a print screen of the scan log.

A crc error means there is a problem reading the file.
Mostly this is because there was a problem when the file was written to the drive.
