Saludos y gracias de antemano. Ojala alguien pueda ayudarme.
Un dia abri un archivo en elcorreo que el Outlook Express me recomendo no abrir. No se si casualmente en ese momento se estropeo el ordenador o el archivo estaba infectado, por que a partir de entonces el ordenador funcionaba fatal, se colgaba a menudo y arrancaba cuando queria. Ya se que parece bastante logico que tengo un virus, pero es que he formateado el disco, he pasado todos los antivirus y antispywares que tengo -AVG, Ad-Ware, Spy-Sweeper, intentaba pasar el Norton Antivirus 2005 antes de formatearlo y siempre llegaba un punto en que quedaba colgado- y sigo sin solucion. Una vez se me abrio la ventana del Errorsafe, pero no le hize caso y no ha vuelto a salir. Despues de formatearlo instale el Windows xp y no me arranca nunca. Asi que voy tirando con el Windows XP 64b Edition, he vuelto a pasar los programas antes mencionados -el norton no por que no funciona con esta version de Windows-, y nada. Ahora el ordenador no se queda colgado, pero tarda mucho en arrancar y una vez que arranca funciona con normalidad salvo continuos cortes en los que se queda parado y no reacciona, el cursor se queda quieto y todos los procesos se quedan parados durante varios segundos hasta que recupera el control.
