Recently i found that a virus(may be javascript virus) which detected as autorun.inf prevent our system to view hidden files. Not like brontox which disable task manager and make folder option dissapear.
If you face the problems listed below your system might have the autorun.inf virus:
- can't view hidden files
- can't open pendrive normally
- can't sign in to YM(Yahoo messenger)
- Firefox can't be open, or just last for 1 or 2 minutes before dissapearing
- internet explorer can't connect to the internet
There are several ways to overcome this problems.
ANTIVIRUS: so far bitdefender 2008 and avg can detect those virus. The link given will redirect you to the official download site. to stay in this page right click and select open link in new tab/window.
download avg at the official site
download bitdefender 2008
(please update after installing the antivirus.)
MY way:
I use different way to remove the virus:
1. click Start>run and type cmd, after that click run,
after the black box appear(command prompt), copy the code below, copy all and paste anywhere in the black box,
if you are unable to right click and paste, just left click and press Ctrl+V.
