“How you can Write protect your Pen Drive” or “How you can prevent your pen drive from getting infected”.
Things to note before doing this:
As the trick will write protect your pen drive, you will not be able to transfer anymore data until you disable it again (works best if you only wish to copy or read something from the drive).
You need Admin rights to work upon the registry editor.

Steps to make your drive Write Protected:
1.    Open Registry Editor by typing regedit in Run dialog.
2.    Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
3.    Find a sub key inside it named “StorageDevicePolicies”. If it does not exist there then we need to make it. Right click on “Control” key -> New -> Key. Name it “StorageDevicePolicies” without quotes.

4.    Now right click on this newly created key and then click New -> DWORD value and name it as “WriteProtect”.

5.    Modify this key and give it a value 1.

6.    Click OK, and remember to restart the PC.
Now no more data can be transferred to the drive but to start using the drive again just give the “WriteProtect” key a value of 0 instead of 1 and restart the PC.

solving the unable to open problem

We all have experienced someday or the other, this problem of WINDOWS XP in which when we double click on the drive it does not open or some dialog box opens up but not the drive. Yes, you know it right; the problem is caused by some virus activity and if you don’t know

how to open this, here is the fix (just make sure that the virus has been removed, else the problem will persist):
When the problem happens, it means that there is a file named “Autorun.inf” in the root drive, but you will not be able to view it as it is a system file. This file is rarely caught by the anti virus. This file makes sure to run the virus and infect your system. This is the file which is responsible to run the dialog box that appears on autoplay. So this is a useless file for sure.
Common sense says to delete this file but even that is not easy as it possesses system, hidden and read only attributes. So,
1.    First go to cmd, type “attrib X:\Autorun.inf –s –r –h” without quotes where X is your drive name which is having the problem.
2.    Now the file is visible and ready to delete.
3.    After deleting the file, close the explorer and open it again or just give a reboot to the computer, your problem is fixed.

solving regsvr.exe problem

Regsvr.exe is also classified as a W32.Imaut
What the regsvr.exe virus does?
•    This worm creates folders and a registry entry to enable its automatic execution at every system startup.
•    This worm also creates a scheduled task to enable its automatic execution at a specified date and/or time.
•    It also creates Autorun.inf file for its auto execution.
Solution to fix the problem:
1.    If the task manager and registry editor is disabled then we need to enable them first.
2.    Delete the Autorun.inf file created by the virus.
3.    Now type msconfig in the Run dialog and click on startup tab.
4.    Look for regsvr and uncheck any options, click OK.
5.    Now traverse to control panel -> scheduled tasks, and delete the At1 task that might be listed there.
6.    Type regedit in the Run dialog to open the registry editor.
7.    Click on Edit -> Find and search for regsvr.exe
8.    Just delete all the occurrences of regsvr.exe virus (do not confuse it with regsvr32.exe which is not a virus).
9.    Navigate to entry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and modify the entry Shell = “Explorer.exe regsvr.exe” to delete the regsvr.exe from it.

10.    Now to actually delete the virus from the system go to system32 folder and delete the regsvr.exe virus file from there (you will need to uncheck the option of “Hide Protected System Files and Folders” in Folder Options to view the virus file).
Reboot the system for changes to take place.
