Grazie per le risposte sempre sollecite e gratite.
Salutoni

Quando avevo il pc precedente un pò vecchiotto, XP HOME SP3 celeron 2,8, AVG 8 lo rallentava parecchio e quindi avevo preferito mettere un altro antivirus.
Considera che avg 8 è nuovo e quindi fatto per macchine di nuova generazione, se il tuo pc non è molto recente ti conviene rimettere AVAST se andava bene prima.
Se il tuo pc invece è recente attendi qualche esperto che ti daranno senz'altro risposta.

Non mi sembra poi così vecchio per giustificare un rallentamento dovuto ad AVG 8 , aspetta qualche esperto.
Ciao

Per il momento ringrazio ed attendo chi mi da aiuto dettagliato come comportarmi.
Ciao.

... effettivamente ci sono come dice @antonpaco tanti programmi in esecuzione .... cioè che vanno ad aprirsi quando accendi il pc

quindi start .... esegui .... scrivi msconfig .... avvio

.....................

per altro ti consiglio avast con zoneallarm .. spiware terminetor ti rallenta usa malwarebytes ... di tanto in tanto pulisci con ccleanear ....
adesso per prima cosa pulisci tutto compreso il cestino ...spegni e riaccendi e fai per prima cosa una deframmentazione ....ciaux e buon lavoro ;O)

---

Fai così:
Disinstalla spyware terminator e tieni malwarebytes per fare scansioni on-demand

Come firewall tieni pc-tools

Disinstalla AVG con il relativo removal tool

Scarica ed installa Ccleaner ed effettua una pulizia completa, anche nel tab registro.

Reinstalla Avast o in alternativa Avira



Provato questo vedi come vanno le cose e facci sapere.

Ciao

Eh si a questo punto è decisamente probabile..

Ciao
