I have Compaq Pesario laptop with Windows XP. I downloaded and ran Combofix. When running Combofix it advised me that I had a virus rootkit of some kind. It finished running and I restarted my computer as it requested. From then on I've had a yellow triangle on my wireless connection. My computer sees the wireless signal but it won't communicate. I tried to repair the connection but it didn't help. I connected my ethernet connection and got the same yellow triangle for my lan connection. I tried Winsock reset, ipconfig /all /release /renew, uninstalling and reinstalling my wireless and lan hardware, finally I tried restarting my modem and router. When I attempted to repair my connection it failed to renew the IP address. My IP address starts with 169, which it shouldn't. I've read as much as I can about limited or no connectivity problems but I've had no success. My wife's computer connects to the wireless router just fine. I love some help. Thanks.

Hello and welcome to the forum!

I will not chide you with the canned DO NOT RUN COMBOFIX unless requested to do so speech but please dont!
That warning is there for a reason!

What is the make/model of the system?
In the beginning there was the command line.

<<My IP address starts with 169, which it shouldn't...>>

I would check the connection settings, ensuring that DHCP is elected and that no proxy server is established.

Right-click your existing connection, click Properties.

Place cursor on TCP/IP and then click Properties button below that screen.

Elect "Obtain IP address automatically" and "Obtain DNS automatically".

Click series of OK options to close screen.

See Configure Your Computer to use DHCP section at http://www.petri.co.il/configure_tcp_ip_to_use_dhcp_and_a_static_ip_address_at_the_same_time.htm if my directions aren't clear.

Thank you everyone for your responses.

I followed Pauline's steps and discovered the Use Proxy Setting was already unchecked. My computer is a Compaq Presario but I don't know the model. I went through all of the DCHP steps listed and the requested selections were already selected. Also, my Firewall will not start from either the lower right hand tray or from the control panel. Thank you.

I suggest that you initiate a post in the Malware Removal Logs forum.

Follow the suggestions in Preparation Guide, Before Using Malware Removal Tools and Requesting Help - http://www.bleepingcomputer.com/forums/topic34773.html and be sure to post the logs in the forum which the guide directs you to post in.

Hamluis,
I took your advise and went to the guides you suggested. I figured out that I was the cause of my problems because I tried to manually remove Key Registries and probably removed one too many. I preformed a system restore and I can now access the internet. Also, Combofix did fix my problem with the redirect and Cloud Protection Virus but I ruined my internet connection. Thanks for all your help.
