How to protect against trojan?? Excellent trick to protect against trojan.
I have explained two major articles on How to recover files from trojan horse and protect from email attached virus. Well these two articles will clearly explains you how to protect against trojan horse and viruses. Well this article directs you to small and damn sure trick to protect against trojan……..
Just make the following changes to the Registry key to protect against Trojans.
Open Regedit and go to ” HKEY_CLASSES_ROOT/batfile/shell “.
Now right click on the default entry and choose “Modify”, and type Edit. Now close Regedit.
You can have preview all batch files before executing those files. Right-click and choose “Open” to run a batch file.”

This tricks uses ” Distructive” interneal/ external DOS commands, like FDISK, FORMAT, DELTREE, DEL etc to wipe out entire drives. So this trick refers to Potential “Trojans”/”Bombs”.
There is one more excellent way to protect against Trojan without hacking Registry is to go to Folder ->Options under Settings and choose MS-DOS Batch Files.
Now edit the associations and choose Edit as the Default for double-click. I hope this is the best trick to protect against trojan.
You can’t use the Folder Options dialog in Windows Explorer to change the default command for MS-DOS Batch Files, without editing the Registry and changing the “EditFlags” Binary Value to “01 00 00 00″ (must be typed exactly like that, without quotes or spaces), which appears under this Registry key (as shown by Regedit.exe):
HKEY_CLASSES_ROOT/batfile.
You can create a new command in the Folder Options dialog, but without using that Registry hack you can’t set it as the default action, which defeats the whole purpose.
