How To File Extension Seemingly

The way to change the Windows default settings so that seemingly the file extension, namely:

1. Double click My Computer to open it.

2. After the My Computer window opens, click the Tools menu and click Folder Options ....

3. In the Folder Options window click the View tab, and remove the check mark in the Hide extensions for known file types

4. Click Ok to close the Folder Option city

And now it looks all the extensions on all files. If in step 2 was Folder Options .... no, I should have congratulated the virus programmers have successfully fooled you, chances are your computer is infected the virus (unless there are people around you are pretty good at tweaking REGSITRY WINDOWS, she was removing suspect Folder Option menu ... but this rarely happens). Now the choice is yours: Exterminate virus or reinstall
