I dont find how to change/remove WELCOME TO tiitle in HOME PAGE

ok i found the solution.
you must go to your site root folder - language- en-gb

then find the file en-gb-virtuemart.ini edit it and find the line
COM_VIRTUEMART_HOME="Welcome to %1$s"
just delete the "welcome to"

COM_VIRTUEMART_HOME="%1$s"

and thats it.

Thanks XARISK, actually I decided to removed all items related with VIRTUEMART in this template, now I am only using K2 component, but I really appreciate your help.
