Not just RAF and RN.
Also I got one after Christmas it put an Autorun.INF file on each had drive which had a call to a boot file - rescycle.exe (sic).
I only found out when I tried to Open a drive and got that error message - I don't usually Open drives using My Computer. Quick search on the internet and I followed the advice on finding and deleting the Autorun files.
It will replicate to pen drives and USB drives too. Must admit, I have two rarely used USB drives so I must check them now. You also need to empty the recycle bin and check backup sets.
