13 hour full scan is ridiculously long

[oldboy]

I don't know much about this but this can't be right.  Recently saw ads I've never seen before pop up and slow down the computer so I installed this program to scan but this isn't right.  Can someone give me some direction?

Hi oldboy,

Can you give an example of what you're seeing?

Does this only happen when online? If so, what site or sites?

Thanks.
