This morning I turned on the laptop, checked my Yahoo email (did not click on any link or download any file), and went off to have breakfast. When I came back NIS said I had to reboot to get rid of threats it had found. I rebooted and looked at the history. It siad it found a high risk virus and it the details it gave were: tcpip.sys and ws.malreware.2.
There was also a red warning sign on the NIS systray icon saying email attachments were not being scanned, so I clicked on "Fix Now" (several times) but it wouldn't fix it.
The problem is that my internet connection on the laptop is gone. The wireless appears connected (ie it would appear that it can get as far as the router) but I cannot access anything on the internet.
I tried restoring the tcpip.sys file from quarantine and I even copied it onto the system32/drivers folder, but no joy. I did a Windows xp disk cleanup, rebooted, and even disbled NIS, still no joy.
I had done a version update of NIS 2 days ago and I suspect this is NIS messing up and wreaking havoc with my system.
What should I do now, given that I do not have my Win XP CD. Should I download the TCP IP file from somewhere else and try to copy it back to where it belongs ?
