Hello,

I have a Dell inspirion one running windows 7 64x. I am not sure what happened and not sure if I have a root or some form of backdoor. I installed several rootkit removers and anti viruses after I started running them I had a windows crash followed by a windows repair request, when I started the repair it got stuck in a sweet loop. Logs posted below.

 

--Edit--

Got the computer to recover, after I ran a few anti-viruses and anti-rootkits one process kept coming up DellOSD.exe I had a Comodo system scan going and then the computer restarted. When it booted back up my computer wont let me alt-ctrl-del and it would appear that every item on my computer has been deleted.
