Malicious url blocked

Today my PC was seriously attacked by a virus.
It was putting messages on my desktop saying that my hard disk was infected and seriously damaged.
My avast virus was putted off by the virus etc…
I could not do anything at all.

I disconnected immediately from internet and have tried to reset my system to an earlier point with my windows system recovery tool. It worked.
I had recovered my pc such as it was before.
I reactivated avast and let it do a thorough system scan. No infections were found.

But now I receive one after the other avast message with urls that are blocked, but the strange thing is that I never visited these blocked urls myself.
I think that part of the virus still is present.

Can anyone help me ?

Thanks… sorry for my English, I am Dutch but can also understand and write in French.

yes possible a rootkit.......and system restore does not remove infections......it is not that easy
