Had trouble with McAfee a few days ago. I finally downloaded McAfee Virtual Technician, which found: Expected File not Present c:\program files\mcafee\virusscan\mcvsoutil.dll
I did an on-line Chat with Dileesh Das. Then phone call with Zack in Louisiana to remove completely then re-install the new McAfee to fix it. It was OK or so I thought. Worked OK all day. Then re-boot (over night) and presto, NO INTERNET !
Since then, I found that either the NIC is zapped or McAfee changed some SETTINGS like under Control Panel, Network Connections, Local Area Connections, Properties. Maybe TCPIP, or Client for MS Networks.
I called Cox, and was on hold a long time. An hour later I got hung up. Called back. I'm still on hold. So has this happened to anyone else?
