Al di là della situazione effettiva del LOG, hai un grosso gap su tre diversi fronti:
1) innanzitutto (ed è una cosa grave) usi ancora AVG 7, il quale è ormai decisamente super-obsoleto. Ti suggerisco di passare quanto prima all'ultima versione (AVG 8.0, che peraltro è anche in italiano) liberamente scaricabile da Aiutamici.
2) in secondo luogo, il tuo Java è l'update 7... mentre ormai siamo all'update 10. Anche in questo caso, ti suggerisco di aggiornare, scaricando l'update 10 a partire proprio dal sito di Aiutamici.
3) infine, la cosa più grave fra tutte: non sembri avere un firewall (ti suggerisco di installarne uno buono quanto prima [su Aiutamici ne son disponibili alcuni abbastanza validi e altri decisamente validi. tutti liberamente scaricabili]).
Trovarsi con un antivirus ultravecchio e bacucco e senza l'indispensabile protezione di un valido firewall, è un poco come "andarsi a cercare i guai col lanternino". Dovresti cercar d'avere almeno un minimo di cura delle cose tue: se tu sei il primo a non averne cura, com'è che speri se ne possan prender cura, per te, gli altri?...
