Then check in your browser for any add ons.
usually I can open google crome an go to facebook or whatever, but half of the times the browser tells me that I have no internet at all. (I have internet and can be on steam, skype and so on.)
Mostly I have to shut down ALL my open browsers and then start up IE or google crome again and I usually have internet for about 5-10 minuttes. Sometimes when I go to sites like "Youtube" it sometimes goes to Yahoo online search and tells me that there is no such site. It searches yahoo after youtube and finds links for it. I dont get it.
I think it started to happen about the same time as I installed some fake virus cleaner **** I accidently downloaded, but I deleted what I could find and looked for viruses with AVG but didnt find anything. I tried to use system restore but didnt help.
I Have a legal windows 8 system but doesnt look like I can format it. it tells me I need a cd for it.
Please tell me you can help me :s
