Can I enable write protect for pen drives?

I need to insert a pen drive into an infected PC to load some anti-malware exe files from the pen drive onto the PC, but I am scared of the pen drive becoming infected. Is there a way I can write protect it so that I can load files from the Pen drive onto the PC and prevent vice-versa from happening?

Some drives come with a write protection switch.  If yours doesn't then buy a drive that has this feature.

If you can't do that then start the drive in Safe mode and copy the files across.  You should be able to do the install as well in Safe mode.  There is no guarantee that the drive won't be infected this way but this is how I do it with infected machines.

If your pen drive doesn't have a write protection switch/lock, get a full-size SD card (not mini or micro) that has a write protection switch/lock (most of them do). It's a sliding tab that looks like this:

SD card write protect
If the infected machine doesn't have an SD card slot, then get an SD card reader that plugs into a USB port. In the situation you're talking about, I think that having hardware-based write protection is the way to go. Regards, Joe

Here is a USB 3.0 drive with a write protect switch
Trekstor USB-Stick is only 25 $. Very good Europe Quality. 32 GB is enough for all malware removal tools.
Pendrives don't get infected, only their contents. Simply delete/format it afterwards.
you can always run the anti malware program on the usb stick, so it gets clean

We run into this every week. We keep an old laptop running Linux just so pen drives and other media can be reformatted safely without running the risk of carrying a virus or rootkit from one PC to another.

We just format the Thumb/Pen drive and load the software back on it. Almost any laptop made in the last five years will work fine for this purpose.
