if the software does not work you can, I think, delete it manually ... that means that you have to go to your registry, in the c: / window /, in the different% folder%, you will know better
your machine, but at this level it is to know it well ...
in short, test the programs before for the moment test on google "topi virus" ....
a virus is registry, startup, dll roaming .. ..ect ect good luck
ps : and do not forget the safe mode ....good luck again
