Ho fatto quanto mi hai scritto ma il problema persiste (in ogni caso non mi si aprono popup pubblicitarie)

Sembra che quando chiudo internet explorer rimangono appesi i processi e se apro e chiudo di continuo si accumulano.
Inoltre non capisco perchè ho tutti qui svchost.exe in esecuzione.

allego di nuovo il log
