Hello All;

I believe I have got a virus in my computer. Every time I turn off and on my computer, the options under folder options are automatically modified. The options are;

(1). Folder Options > Hidden Files and Folders > 1. Do not show hidden files and folders
> 2. Show hidden files and folders
(2). 3. Hide Extenions for known file types

Whenever I turn on my laptop (Microsoft Windows XP SP3 OS), Option 2 (Show hidden Files and folders) is checked. I uncheck this option by checking/enabling the option number 1, but still my computer keeps repeating the same thing evertime I turn it ON.

Option 3 (Hide Extensions for know file types) is also unchecked when my computer restarts.

Please help if you know anything about this virus

Regards,

Hello All;

I just went through some online investigation about this virus and found out below details. And it works! I just did it on my computer.



Virus Overview
There have been a number of recent malicious programs exploiting the default behavior of Windows operating systems to hide file extensions from the user. This behavior can be used to trick users into executing malicious code by making a file appear to be something it is not.


Virus Description
Multiple email-borne viruses are known to exploit the fact that Microsoft Windows operating systems hide certain file extensions. The first major attack incorporating an element of file extension obfuscation was the VBS/LoveLetter worm which contained an email attachment named "LOVE-LETTER-FOR-YOU.TXT.vbs". Other malicious programs have since incorporated similar naming schemes.

Impact
Users can be tricked into opening a file that appears to be something it is not. A file that appears to be innocent based on it's viewable file name may contain malicious executable code.
