General question about offline hard drive
I have several offline external hard drives (EHD) and would like to connect to them but suspect they might have a virus on them. I assume that some bugs can jump to your computer hard drive as soon as the EHD is connected. If so, when I scan them, I assume I also have to scan my entire computer?
If all of this is true, I have some hard drives with several old backups on them and need to delete much of it before starting, because there is more than a terrabyte and a lot to scan. So I assume it would be best to connect the EHD, delete unwanted files (a terrabyte or more, which takes a lot of time) and then run a scan on both the computer and the EHD?
Would appreciate a reply by someone who is up on these things, I know this will take hours and I want to cut down the hours. Just to scan my active hard drive takes hours. Thanks in advance for any reply
