I came across a new virus that have been spreadig through usb drives.The malware is known as w32.USBWorm.
Once affected you get the message “I Dnt hate Mozilla but use IE or Else..." This virus also shows error messages when you open youtube..It shows youtube IS BANNEDyoutube is banned you fool,The administrators didnt write this program guess who did??MUHAHAHA!!"Orkut is banned you fool,The administrators didnt write this program guess who did??MUHAHAHA!!"and it also plays an audio clip of evil laughter..This is a silly virus.
To get rid of this you just have to delete the virus file.To do that follow these steps
1)Go to Task Manager (Press Ctrl+Alt+Del)
2)Goto Processes Tab
3)End all processes with the name svchost.exe (only those with your user name to its right)
4)Note that you shouldn't end the system process svchost.exe(the SYSTEM process)
5)Goto Start>Run
6)Type in regedit and click OK
7)Navigate to HKEY_LOCAL_MACHINE,SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\ Folder\Hidden\SHOWALL and on the right pane doubleclick CheckedValue and change it back to
18)Now navigate to HKEY_LOCAL_MACHINE,SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run and delete the winlogon key on the right pane
9)Now close regedit and searh your computer for a file named svchost.exe (enable Search hidden files and folders)
10)You will see a file with a green H icon in the search result(There will be another svchost.exe file in system32. Ignore it.Its a system file.)
11)Open that file location and delete the the folder that contained this file.
13)Now the virus is gone.This type of virus spreads through usbdrives(Which automatically runs the virus file.)To stop such infections you can disable the autorun feature.
