Is my computer secure?

I was using Rkhunter and this was displayed.

I had opened firefox and some ads were displayed because i forgot to install adbockplus and well в while later firefox was freezing эксперт well some other apps.

I have heard that malware-вирус хан now automatically execute despite enabling/disabling ads. Just want to make sure i am not infected in anyway.

Thank you.
