I have a Gateway W323-UI1 Notebook. I am having a bit issue with internet connectivity here. I was facing a bit virus issue from last few week. I am scanning my pc through AVIRA and it looks effectively stopping the virus also. But I am having problem with internet. Whenever I try to connect I am facing a page not found message. This thing keeps on appearing. I had tried so many things to fix the problem but nothing works. What should I do to clean my pc.
