Ran all scans, all came out clean. Ran ccleaner fixed issues but still cant go online.
My wireless network icon says I'm connected but when I open internet explorer I get the message "Internet Explorer cannot display the webpage"
Everytime I want to update my anti virus database it fails saying theres no internet connection.
Any other suggestions?

"tdss log"

Thanks, no further clues there, try the Windows repair, as per my previous post.

2: Use Windows own program SFC ( System File Check )

3: Run chkdsk ( Check Disk )

I already have Trojan remover installed I always do a scan with that everyday & it comes out clean, I also tried hit man and it found no viruses.
I'll try the programs in that other link.
I think the problem has to do something with the registry & the tcp ip stack.
I still think my computer is infected cus in task manager there's multiple svchost.exe processes running
