Hi Damian
Thats a seriously compromised system you have

Microsoft Antispyware has
grouped some of the filenames together but they relate to different
infections including backdoor trojans and password stealers, from looking at
that log It very likely you will have more files on your system.
There is files from all these infections showing in the log
Backdoor.Fivsec
TrojanDropper.Small.acg
TrojanDropper.Small.we
Trojan Downloader.OF
Trojan LdPinch
Trojan.Abwiz.B
Trojan.ZarCry
Trojan.Secup
Trojan.Pepop
Trojan.Crypt.i
Trojan.Crypt.c
Try these removers first and then if you have more problems post back the
scan results for both, there may be a trojan filename entered with
explorer.exe in the winlogon area of the registry so they both start with
Windows but we can easily use Hijack This later to show if thats the case,
First step is to remove any files that MS Antispyware may of missed and reset
your security settings.
Download smitRem.exe and save the file to your desktop.
