Inactive Malware I think

[Inactive] Malware I think

Hi guys
Im new here.
Have Acer aspire 5532 running Windows 7
Last week picked up a bug which I thought was a malware because it said that my laptop was totally infected and to cure it all I had to do was buy thier anti virus, I believe it was called " antivir " It totally ******* everything. No matter what I tried to open it said the file I was trying to use was infected and wouldnt open it. I tried using Rkill but it did'nt get it. I could'nt even use my cd drive. It shut down my antivirus too.
One week on I switched on the laptop to find it was gone. Everything works fine apart from one thing, I cant log on to internet. laptop is showing connected to router with a good signal and internet access but it wont display any websites. I even tried attaching to router via a cable but no joy. Currently using my old pc to connect via cable so I know router is working at least with cable.
If I go into device manager it's showing a driver issue with "microsoft virtual wifi miniport adapter" Could this be the problem? Obviously I cant log onto web using laptop to find wifi driver. Anybody any ideas?
Laymans terms please as I am not very pc literate.
Cheers Davey
