I just want to make my pendrive write protected just to make sure, when I insert it public PCs like in cyber cafes in order to just read the files, it doesn't get virus affected. How can I do this?

You could always try locking the drive using diskpart.
Open CMD as admin and type diskpart
.
When diskpart loads - type list disk
This will give you a list of drives in your machine.
Select your USB device using the select disk 1
command (where 1 is the number of your USB)
Use attributes disk set readonly
to set the drive as read only.

Unless your USB drive has a physical switch, this is not possible. You cannot enforce something like this using a software solution, especially when you do not control the system.
...or your hardware pen has to be projected to have only authorized access, that means that there is a microprocessor inside with a "nano operative system" that asks for authentication and only after allow to read and write. So not a normal pen drive. – Hastur – 2014-07-11T12:00:38.220
There are some low-level manufacturer tools that can enable/disable a write lock on a drive - though the whole security of this system is based on the fact that these tools are not publicly available and there are no standards regarding such mechanisms (otherwise - anybody could unlock that etc.). So you could order read-only flash memory with some files written in china - or try to get a manufacturer tool for your exact model of memory - but I don't think that's going to be easy ;) – unfa – 2018-08-29T08:42:23.270

If your stick uses the NTFS filesystem, you can do the following. If not, consider copying the files off of the drive, then format as NTFS.
Do the following:
Properties
Change
button, and answer yes to the UAC prompt if applicable.Everyone
and click Okdeny
for Write.From this moment on, no one can change the drive anymore. If you want to make changes, Repeat the above steps and remove the checkbox for write in the deny
column.
Although the screenshot is dutch, it is showing the endresult.
this method requires NTFS file system – msoa – 2018-11-02T20:28:18.280
