Windows 7: Virus problems causing network issues?

Virus problems causing network issues?

I have recently upgraded my CPU and as part of that re-installed Windows 7 home premium x64. I have an updated/running copy of Norton Antivirus on as well. I posted about this problem in networking and was sent to this forum. As It began to install updates I have 2 issues that may be related:

1. Network and Sharing Center won't open - When I click on the link at the wireless icon or go through control panel, nothing at all happens when I click on "Open Network and Sharing Center". I otherwise can connect with no problem to my home wireless network and access the internet with no problems. I just can't open the center at all. Other control center options don't work either

2. Microsoft Explorer and Google Chrome both won't connect. I get an error "Proxy server not available" on Chrome and Explorer just tells me IE can't display the web page. Fortunately, I have Mozilla Firefox and I was able to go into settings and disable the checked box to connect to the Proxy server which allows me to use (see note below about IE)

What I have done:
*** I have gone into Control Panel / Network and Internet / Internet Options / Connections / LAN Settings and "automatically detect settings" is checked. "Use a Proxy server" is not checked. Everything is grayed out however and I can't change it one way or another.
*** I have gone back to an original "restore point" and the system will work somewhat better for a short time but then will start having problems again as above.
*** I have downloaded Malwarebytes and completed a system scan. It did identify 13 items which it removed. However, the system is still not working properly.
*** I powered off my wireless router for 15 sec and then restarted it.
*** I have done a search on this and have seen many conflicting directions. I am afraid I have an issue with a virus but don't know how to approach it.

Any help or guidance would be fantastic!!

Thank you,

Don

Download the Farbar Recovery Scan Tool
Select the version that applies to the system.
Save to the Desktop.
  • Double-click the downloaded file to run it.
  • When the tool opens click Yes to disclaimer.
  • Press the Scan button.
  • FRST64 makes a log (FRST.txt) in the same directory from which the tool is run (Desktop).
Please provide the FRST.txt in your reply.
The first time the tool is run, it also makes another log: Addition.txt
Also post the Addition.txt in your reply. It will present a list of the programs that are installed on your computer, and any undesirables can be identified.



Also, download Farbar Service Scanner
