Internet muy pero muy lento, puede ser algun

Buenos dias
tengo este gran dolor de cabeza que me esta matando ya por 4 largos dias
la verdad no se que paso exactamente, pero ya son 4 dias que mi internet esta demasiado lento
Mi pc es una

AMD: phenom II X2 560 processor 3.30 GHz
Ram: 4Gb
OS: win 7 ultimate (32 bits)
HDD: 500gb (partido en 3 unidades)

mi velocidad es:

y esto no se cumple, me descarga archivos de 10mb en 20 a 30 mins
llame a la compañia que me brinda el servicio y me dice que la conexion esta bien y que quiza tenga algun virus

Formatie el disco duro C, y volvi a reinstalar todo el sistema
pero el problema persiste, el internet sigue lento
y la verdad ya no se que hacer

revise mi pc con el Tcpview y con netstat -an y ambos me mandan esto: (la compañia de internet me dice que no deberian de aparecer muchos "ESTABLISHED", a lo mucho 2
Ya desactive el Firewall de windows y el del antivirus, pero cuando hago eso, aparecen muchos ESTABLISHED en firefox
