Prevent virus attack....


Autorun.inf

1) autorun.inf virus use the autorun feature of windows to spread themselves between the root directory of all the dirves on ur pc as well as any external drive. This causes the virus to run every time an external device lik a pen drive is inserted or every time u double-click the drive icon in windows explorer.

The forst step 2 remove the virus is 2 disable the Autorun from ur PC. To do this,

Click on ‘start > Run’

And type ‘regedit’

Scroll down to the key

‘HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ Explorer’

Double click NoDriveTypeAutoRun’ on the right hand panel and change the ‘Value data’

From ‘91’ to ‘ff’.


Then again scroll down on the left hand panel to

‘HKEY_USER\ DEFAULT\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ Explorer’.

Here again change the ‘value data’ of ‘NoDriveTypeAutoRun’ from ‘91’ to ‘ff’.

Exit from the registry editor by just closing it.

[Note: use backup before editing]





2) Then click on ‘start > Run’ and type ‘msconfig


Here, disable all the unnecessary or unwanted programs.

3) Reboot the system to sfe Mode (Press F8 on starting) and delete all the autorun.inf files from all drives in My computer and also from external storage drives.

Create a folder named ‘autorun.inf’ in every drive and partition’s root folder,also do the sme on every pendrive u have.
