mic detected win NT/Beagle.gen virus on my comp

I am told as a solution to go to the onine onecare scanner. I tried this
once and it never finished. Now every time i retry it just won't work
anymore. I have the evaulation trial version of onecare on my computer and i
can't even open it. it says contact support or restart computer. Support
won't help and restarting won't help.

How can i remove this virus? I can't install a virus program but i can
access the interent as i am able to type this message over the internet.
