Internet Connectivity Problem

Hello,
I am logged in as administrator.I could only find a hidden shortcut to Documents and Settings in LocalDisk:C.Its size is 0 bytes.I tried to change permissions but I get the error message:An error occurred while trying to share Documents and Settings.Access is denied.The shared resource was not created at this time.
Thanks!

Hello,
I reinstalled comodo and allowed al the safe applications but internet didn't work.I added my parent proxy port to the port list but it also didn't solve the problem.I used network diagnostics in IE and it asked to turn on TCP performance improving settings.Then it said problem still existed and asked to turn off TCP settings not compatible with the router.At last it said windows could not solve the problem.
Safari browser gave winsock error:10022 and norton internet security gives the message:Error "Symantec Email Proxy cannot scan your email messages because your network is not properly configured" (1003,13) on start up.Symantec website said this is because the computer is infected.But the computer does not have any serious infections.
The file sharing program used in the network DC++ also doesn't work(I get TCP/TLS error).
I uninstalled comodo but the problems persist.I had used TCPoptimizer but I restored the settings back to windows default,but it didn't solve the problem.I tried resetting the TCP/IP stack before uninstalling comodo and after uninstalling comodo firewall,but it didn't work.
I had to do system restore in safe mode(it failed thrice in normal mode previously).Now I have to reset the TCP/IP stack before shut down and enter the IP settings on start up as before to get internet connection.Please help.
Thanks!

I see you are under Vista. Vista doesn't have a Documents and Setting folder anymore. The folders you see are only for programs that are being run in virtualisation mode.

The comodo folders Eric Cryptid is referring to are under H:\Users\[your username]\AppData\Local\Comodo and/or H:\Users\[your username]\AppData\Roaming\Comodo. Now you can delete these folders when uninstalling Comodo as described here: https://forums.comodo.com/help_for_v3/comprehensive_instructions_for_completely_removing_comodo_firewall_pro_3_info-t17220.0.html .

P.S. Could you please make paragraphs when writing. Your posts are very hard to read without structure.

Hello,
I checked those folders and they were empty.I had used the comodo uninstaller before but it couldn't find any registry  entries.I used it again but this time also it didn't remove anything.I couldn't find any drivers or registry keys given in the post.
I searched for comodo and found some keys in HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY CMDGUARD\0000 but could not delete it.I get "Access denied
" message though I am logged in as the administrator.I found some more keys but they can't be deleted.
Is this post problem related to the problem?

When I have connection problems I find only a single network with local access in Network and Sharing Centre.But after I reset the TCP/IP stack,restart and enter the TCP settings,I see two networks which access changing from local to local and internet after some time.
Thanks!
