1TB External Hard Drive Infected with Win32:Malware-gen

I plugged in my external hard drive filled with important files into an infected PC and now whenever i plug in that same hard drive into my laptop, all the folders have an “.exe” at the end.

I want to preserve all files in the external hard drive, how do i do that?

I’ve attached a pic of one of the folders i tried opening but it got sent to the virus vault.

If the files really are infected, why do you want to preserve them ?
Simply clean the system and use your backup of the files.

Follow the instructions > https://forum.avast.com/index.php?topic=194892.0

because this is the only backup of all the pictures i have since 2002.

I tried using the same external hard drive on another laptop that i am about to reformat and without any antivirus installed in it.

although the folders are changed to .exe with a file size of 293kb, I could still get into the folder just by clicking it and accessing the files.

so the question is how do i disinfect the external hard drive without deleting the files?

In the guide Eddy gave link to, scroll down to [b]SPECIFIC INFECTIONS LOGS[/b] and follow MCShield instructions

This log you copy and paste here … The others you attach

Also note that disinfect a file can only be done if they are infected with a real virus that inject malicious code in legit files.
You can not disinfect a trojan as the hole file is the trojan

If that is the backup, you still have the original files.
Clean your system, wipe the drive and put a copy of the original files on the drive.
