A RAR file is split into two files as lmpro.ro1 and lmpro.ro2, which are located under C:\System\Libs\. When extracted, the RAR file creates the file T-VIRUS.EXE. It is actually a text file containing the following message:

What is T-VIRUS?
T-VIRUS is not a type of virus, instead it is a system file, specially designed & created for you.
T-VIRUS crashes the main system of your phone, i guess it is the right time for you to go to your service center, or buy a new phone.
Newer & higher version of T-VIRUS, coming soon.
If you have Cabir, feel free to send it to me, i'll appriciate it very much.
