i suggest u install fexplorer first.
select commwarrior application & close it by pressing d'C' button. u may have to press/hold the menu key.
then go to fexplorer and open it.
go to C: > system/apps.
-delete the folder named 'commwarrior'.
then go to > System/Recogs.
-delete commrec.mdl.
then go to > System/Updates.
-delete comwarrior.exe, commrec.mdl, commw.sis.
lastly go to E: > and repeat all above deletion steps.
close fexplorer
open manager and remove commwarrior.
if u want to avoid manual steps, download and install simworks
or f-secure anti-virus. they will do the removal job.

have fun !
