Since you have run the McAfee stinger, I will assume you have seen this document already. Required Reading - Home User Assistance Malware Troubleshooting
Try to download the free version of this program onto a usb stick from a non infected pc and rename the download and installation files to something you can easily remember. When you rename the files malware may not seen them as a threat thus allowing you to install them. After installation check for the latest updates and run the program and let it clean everything it finds and reboot the computer. Then see if your issue still persists.http://www.malwarebytes.org/mbam.php
Any chance you might have Firefox or Opera as a browser? Maybe one of those will allow access.
thanks for the tips. I did know about the "required reading - home user...etc" document. I decided to run the stinger program and download the free version of anti-malware program. It found and fixed 11 problems, but I'm still experiencing the same problems. I'm not sure if the stinger program found anything. When it finished, it didn't really tell me anything...it just stopped and said ready at the bottom. I'm about ready to give up and try to find a different anti-virus program . I would like to chat with a support tech but I can't get to the chat screen on that computer. I will download firefox and try to get in that way. Again, thanks for the tips.
ok...got mcafee to work. First I tried to use a different web browser to access mcafee. I downloaded Firefox and Opera. Firefox did not download to my computer. When I used Opera to access mcafee, it gave me an error saying there was a file on my computer that was redirecting my request to a different website. The file started with 127.0.0.1...the same way the host doc looks. I ended up going to my hosts file (c:/windows/system32/drivers/etc) to check for errors. It looked clean, but I deleted everything after the "127.0.0.1" and was immediately was able to access mcafee web pages. I hope I didn't mess up anything by doing this but it worked. I hope someone else will find this information useful.
