Dllcache directory and files are blue (compressed?)

Reformated HD and loaded Win 2000 (SP4) and tested.

How can this be????

False positives? That is very likely scenario.

Scan some of those files in Virustotal and see if any other AV reports anything.

Don't use Clam as your primary AV, and if none other AV detects anything report those files as false positives to ClamAV project at https://www.clamav.net/sendvirus/
