Can the Firestore pass/catch a virus from/to a pc? Couldn't find the answer on google. Anyone know?

Eric, if the virus has set itself up to "auto run" and your PC has auto run enabled when you content devices, then yes, it is possible for the virus to infect the PC.

I personally turn auto-run off on my systems, mainly "control freak" issues :-)

Check the firestore drive for any autorun.inf files in the root folder. You can open these in a text file and they will show you what application is being run when connected.

Hope this helps,
Roger
