Remove Ads by Easytoshop, smartcompare, shhopndrrop, dealsfinderpro, ddeal4reoAl from the Computer

I have a hp pavillion running on windows 7, I haven't used my laptop much recently as I have been on holiday and didn't take it with me. I was using it last night and all these ads started popping up and new tabs kept opening with offers for $1 iphones and thing like that. The ads say 'ad by easytoshop'
I searched up that virus but can't find a programme under that name on my computer but there were a few others such as:
-smartcompare
-shhopndrrop
-keep last two tabs
-dealsfinderpro
-ddeal4reoAl
-coupscanner

They all sound suspicous and related to this so I tried uninstalling them but it won't work.
Can anyone help me out here what should do and how do i get rid of them? I just click uninstall and nothing is happening I also tried restarting the computer and trying again but had no luck.
