I had exactly the same problem. However, when in safe mode I used the ESET uninstall utility and now I have no network access (either cat5 or wireless). I've made 3 calls to the helpdesk and ecah time they have suggested different things - all to no avail.
On the first call I was asked to delete all the network drivers and the reboot - result no change
Then I was asked to run a winsock repair tool - result nothing
Then I was aksed to again delete the drivers and reinstall - nothing.
As a result of the ESET uninstall program I now have a laptop that can not connect to the internet!
Using ipconfig/all no network adaptors are found
The ESET uninstall program must disable something - which means it can be undone. I just need to know how and URGENTLY
