I ran PrivaZer on defaults a few days back and now some of my apps and websites sometimes becomes lethargic during opening like hang for some seconds then start running. Shutdown also longer than usual. I can't log in to one shopping site despite everything done correctly.
I think Privazer tends to over clean.
Had it removed but issues still remain.
FYI, scanned with Avast IS, EEK, KVRT and AdwCleaner................found nothing.
