Prevents security threats and allows the system to display the exe extension forever

When we receive an email, we usually pay special attention to executable files to avoid viruses. But the current virus disseminators come up with a way to deal with this, that is, to disguise files. Sorry, many users think that this is just a common image, so they can open it with confidence. This is the trap of others and is infected with the upper body.

In fact, many friends will say that you can set the display file extension in "Folder Options". Can this problem be avoided. The reason is good, but the display extension is also inconvenient. For example, you must enter the extension when renaming, and many users are not used to displaying all the extensions. Therefore, we can only display the extensions of certain types of files, such as EXE.

Open the "run" window in the "Start" menu, enter "Regedit", Press enter to open the Registry Editor, select "HKEY_CLASSES_ROOTexefile" on the left, and right-click the blank window on the right, select "string value" in the "new" menu and set its name to "Alwaysshowext ". After modification, close the registry. Restart the computer so that we can see that no matter whether the extension is displayed in "Folder Options", the file extension of the EXE type will be displayed.

The virus exists in the form of EXE and COM and other script files. To ensure security, we can go to "HKEY_CLASSES_ROOT, add the "Alwaysshowext" string value to the following items: Prepare file, comfile, batfile, scrfile, JSFile, JSEFile, VBEFile, VBSFile, and WSFFile. No matter how disguised, they cannot escape our eyes.
