I'll never browse the web using an Administrator account again because out of nowhere on Friday whilst browsing something (probably a virus or worm) wiped out allot of my hardware configuration such as
"HKEY_CURRENT_CONFIG\CurrentControlSet"
"HKEY_LOCAL_MACHINE\ControlControlSet"
and so forth.
My installed antivirus, antispyware, and firewall didn't protect me one bit! Restoring a registry backup, and a system restore point didn't work, needless to say I reinstalled everything.
