Como remover infecção, provável ihavenet.com... Computador lento e travando

Após fazer a pesquisa no google, ao tentar entrar em qualquer resultado da pesquisa a pagina é redirecionada. Na aba  tanto do firefox, do IE e do Chrome aparece ihavenet e logo em seguida é redirecionada para diferentes paginas da internet.
Tentei instalar todos os tipos de programas para remoção de malware, seguindo instruções de diferentes lugares na net.
Instalei em meu computador os seguintes programas, rkill, Malwarebyte Anti- Malware, Adw Cleaner, Ccleaner, SUPERAntispyare e por fim o Spy Hunter.
Este último foi o único que conseguiu localizar o programa infectado.
Segui as instruçoes para corrigiri o erro e mesmo assim o computador continua infectado
Meu computador está lento e está travando muito e continua redirecionando a pagina do google.  
Os tópicos sobre vírus redirecionadores do google e sua solução não me ajudaram.
Gostaria que me ajudassem a identificar onde está o problema e a forma de solucioná-lo, pois o meu computador está travando muito.
Desde já agradeço pela atenção.

Cecília.

Obs: Meu comp é um Dell Inspiron 14R, processador Intel Core i3, Sistema operacional 64 bit (acho que isso eu também tenho que informar)...
