McAfee alerted I had a Trojan (Exploit-CVE2010-0094) on 12/9/10 & it was quarantined. Nothing else except tracking cookies have come up since. I was able to connect to the internet until 1/8/11.
I can connect to my wireless network, but it says "limited access" & when I open Internet Explorer, the webpage cannot display on any website. When I ran the troubleshooter, it said problems found - "The Diagnostics Policy Service is not running".
I contacted cable company & it's not an issue with the service. I can connect to my wireless network & the internet using my phone & my old laptop. They had me try direct connection from laptop to modem & still no internet.
I called Dell because I'm still under warranty (apparently for hardware only). They had me do a few things. Couldn't find a restore point. Found out both my wireless & LAN ipv4 address starts with "169" in normal and in safe mode. Could not reset/renew IP address. They determined there must be a problem with my system registry. Told me I should back-up my files & they could walk me through restoring the factory settings. Then the guy transferred me to Dell's Software Team. They told me I probaby had a really smart virus & that he could "directly reinstall the operating system" for a fee (up to $239).
I don't have the money to do that & I would rather save the factory restore as a last resort. An IT friend told me to download combofix on flash drive & run on infected laptop. I did & I still can't connect to the internet. He said I'd probably need to have somebody look at it. (He lives out-of-state.)
Somebody else suggested that I uninstall the driver for my network adapter & reinstall it. Tried & that didn't work either.
Not sure what to do, so I thought I'd post here to see if there was anything else I could do. Please let me know if you can help.
