Still hanging...

I've still got problem with my computer which can't let me surf the internet as I usually do in my free time. I have tried to ask some people how to get over with the trouble, but it was still to no avail. Any anti-virus software doesn't seem to work on my computer, though I believe most of the spy ware bugs must have been inspected and removed from it. However, it still ended up with invalid connection. If the problem remains, I will have any computer store technician take a look at it and that may be the quickest solution to the problem.
