I'd say Automatic Updates are set to run at 3:00am daily, and then your computer auto restarts after the updates to install some of them. Check Control Panel > Security Center > Automatic Updates.

You have some serious Trojan Virus problems. I don't know how you got a HJT log if the computer keeps restarting. I see you just joined, so let me say welcome!! Just so you know, Service Pack 2 or SP2 is available. Service packs increase the safety of your system. Also Internet Explorer v6.00 SP1 (6.00.2800.1106) is out of date. In HijackThis, put a check mark in the following and fix.

Win32:Refroso, I don't like the looks of this and my abilities end here. It could be a false positive. But with the symptoms you have and some of the information I have found would feel much better if you go to a malware removal forum for more thorough scans and mostly an expert opinion. At this time I am going to supply a link where we send folks for Malware issues. Please follow the instructions at the link provided and post the required logs, it's important you post the logs. You will need to register and create an account there here is link, Please link back to here too so they know I sent you. Let us know what the outcome is.
