BIOS virus

I have this BIOS virus in my computer for 2 years.


The virus inserts bbbbbb into keyboard whenever I type.


It is certainly not hardware fault on the keyboard.


Because this virus haunt my input in a cyclical manner.


No problem for a few days,
then the symptoms start to surface mildly not inserting too many bbbbbb initially, and a few days later went into full blown harassment.


It took me 5 mins just to type the above.


It is intelligent in a way that whenever I use backspace repeatedly to remove unwanted bbbbbbbbbbbbbb, it will jam the backspace at time and force more bbb into the keyboard hence making typing extremely inefficient.


I tried all sorts of virus scan, mbr scan, and even rescue disk scan from 5 to 6 of the popular virus scanner. To no avail.


I even tried to switch from Windows to Ubuntu OS.
I also tried format the harddisk and reinstall the OS,
again, good for a few days then problem surface again.


just to show you the sample without trying to backspace edit the typing, i will type in a to z in the next line.

I tried to get in touch with the manufacturer of this laptop but they don't respond to my request, what I ask from them is a copy to refresh my BIOS.
