problema rallentamenti ciclici

[nicacin]

Salve a tutti.
Mi scuso in anticipo ma non sono un esperto e spero di descrivere il mio problema il meglio possibile:

da alcuni giorni subisco dei mini "blocchi" ciclici di WIndows nel senso che, per esempio, muovendo il mouse o utilizzando una qualsiasi applicazione (musica, giiochi..) ciclicamente mi si blocca tutto per poco meno di un secondo,per poi riprendere e poi dopo alcuni secondi si riblocca, il tutto con intervalli regolari:

spero di essermi spiegato

non avendo installato nulla di nuovo, suppongo sia un qualche virus o malware o chissacosa, anche se NOD32 non mi ha avvisato di nulla (ho solo questo programma di difesa cmq )

non essendo un esperto non so cosa posso fare esattamente, se qualcuno mi può illuminare e ha bisogno di più info me le chieda pure..

thx a tutti

p.s. posto la schermata del Task Manager perchè ho la forte senzazione di avere malware, se qualcuno nota qualcosa di "strano" srebbe ottimo



e anche un log scan :
