I have a laptop HDD that contains one or more viruses. I want to remove it and connect it via a SATA-to-USB connector to my desktop computer, right-click the drive, then click "scan for viruses". Is this safe?
the safest way to solve your problem is just to boot up from usb flash that is designed to cure viruses and actually cure them all. look at Dr.Web® LiveUSB, Kaspersky Rescue Disk and any other antivirus that has free live usb image disk for download. using this approach you don't even have to get your hdd out of notebook.
