If you think that
USB flash/pen drives are infecting your system with virus, then try to block
all USB ports so that your system will not accept any USB flash/pen drives.
To do this
Type “REGEDIT” in
RUN command window or if you are using latest Windows operating system you can
type in Start up menu down run bar.
Then it opens
system registry.
Now browse the
Registry like this;
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR
Now Click mouse in
the right side pane and double click on the registry key START and change the
DWORD value as 4.
Now you can restart
your computer to get effect of the changes in registry. Your USB devices are
not accessible because your system USB ports are blocked.
By default DWORD
value is 3.
To make your USB
ports accessible do the same steps and change the value back to 3 (default
value).
And restart your
computer to check the effects.
Using
BIOS
You can block USB
ports even from BIOS setup itself.
This is very safe
and effective.
To do this:
Start your computer
and press ESC, F6, F8, F12 as mentioned in user manual to enter in BIOS Setup.
