I have Kaspersky Total Security. I have many external hard drives, which I think could be infected. What's the best way to scan these external harddrives so that I can use them, without the infections coming into my laptop?


Usually when I connect external harddrives, it automatically opens up. I assume this would infect my laptop before getting a chance to scan it.

Is there a way to scan it before connecting to it? Thanks.

catch-22 situation.

can't scan an external drive unless connected, don't want to connect and get infected.


you can at least turn off AutoPlay, via Control Panel so the drive doesn't do any auto startup things.

once connected, right click that drive from File Explorer and your AV software should have an entry in the context menu to scan it.

Instead of reading this, why not do a backup of your PC.

You won't regret it.

The classic way would be to boot an ephemeral session, having disconnected any internal hard drives, using previously created bootable media (preferably DVD so unwritable), either Linux Live or a dedicated recovery/emergency disc.


You used to be able to create a Rescue Disk 10 directly from within Kaspersky, but it seems from 2015 that was no longer there as an option, the procedure for creating a Rescue Disk is given here:




I've found the Kaspersky Rescue Disk 10 scanner very satisfactory, and with your own system hard drive(s) disconnected, no re-infection can occur. More modern systems lack an optical drive, so as their instructions indicate, a bootable flash drive is becoming more the norm. You can get secure ones with a physical write prevention switch if you want to be really cautious.
