No more network access?

I cant get my laptop to connect to the internet. I use an inspiron 1525 that gets it’s connection through a wire from another computer on the network. It seems to connect but when it does it says "connected to: Unidentified network limited or no connectivity".
I tried with all the anti malware and firewalls off still nothing. Recently I got infected with system security 2009 BUT I got it out ran safe mode and used a registry cleaner and anti malware to clean it up. That whole time I was in safe mode I had net access but once I restarted the comp after the changes I could no longer connect to my network successfully. Please help me!! how do I fix this Problem????

I currently have Registry Patrol, but don’t think it works very well. What do you think is the BEST Registry Cleaner/Scanner?

Also what do you think is the best anti-virus and spyware software?

Computer Registry Cleaner?

I just bought a ew Dell Computer (Windows Vista) and I had a "Registry Cleaner" that I had bought from me old computer (Windows ME version) and I had installed it on my new Dell computer. Well I scanned my computer and there were like 21000 problems that the Registry Cleaner detected on my new Dell computer. My question is was I wrong for installing this Registry Cleaner on my new Dell computer and the problems that were detected may not really be a problem. I do not want to destroy any important updates on my computer. Please help!!!

Shouldn’t we be able to rely on the operating system to keep itself in stable condition? My registry cleaner found 6000 errors this month alone. Since the OS is such an important function of the computer; why can’t it pick up after itself?

Has anybody else heard of this? I recently upgraded to XP and during the process my Virus protection was turned off. Before i got it in place something slipped through. Now I keep getting these pop ups that say… Message service
Bla bla bla go to this website and it will clean these pop ups . When you go its trying to sell a program for a registry cleaner
How do I block this and remove these adds.
It looks like a scam to get me to give out my info ect. Help .

There website is registrycleanerxp.com
