Found this site by searching for info on SCVHOST.EXE, which is different from svchost.exe I've found out; downloaded a "security suite update 6.0" from charter.com (FSECURE) and now my PC endlessly cycles through a file error/network-shutting-down-now routine. Hopefully this site can help me resolve this issue.
I've been computing ever since I got my C-64 what seems a hundred years ago now, build my own units and upgrades - which is why when the tech told me to contact the original manufacturer he had no comeback when I told him he was talking to the original manufacturer. Since the PC won't boot to the desktop, it's not his "problem"....
Anyway, looking forward to solutions and some further insight into this mystery box I can't seem to spend more than a few hours away from without going into withdrawal.
