I’ve installed Simple New Tab by myself. I thought that it’s a useful app, but I was wrong. Now I understand that it’s nothing else but adware that keeps displaying dubious ads. The problem is that Simple New Tab ads some time before offered me to update Java and I hastily took the offer. Can it be that I’ve infected my PC with a virus? It appears to be more sluggish than before, sometimes it even crashes. Besides, I keep receiving suspicious ads. Please help ASAP!
