Hi anyone willing to help,

I will now try to describe any relevant background and symptoms. The log files are pasted in the end. Any HINT would be much appreciated.

Background:
- bought a second-hand laptop about a year ago via Ebay from a guy with a huge number of positive ratings (D610, 2GHz, 2GB RAM, 75GB HD)
- legitimate copies of Windows XP Pro 2002, Office and others istalled, no install CD-s (that's why I'm here, otherwise would have formatted the hard drive and re-installed)
- installed SP3 and all security updates
- was stupid enough to install a crack to Eset Nod32 antivirus right after buying called TemDono or something, gives 31days to expiry until 2050, for a year everything has been fine, though (now uninstalled both Nod32 and the crack, no more cracked programs on the computer)
- maybe three weeks or so ago my partner started to download movies via BitTorrent
- Nod32 recognized some movie files as trojan downloaders and terminated downloads
- I think its log said it also prevented running others that were already downloaded
- some movies wouldn't start but just said 'use Windows Media Player'
- around about then all the funny stuff started (see description below)
- no entertainment has been downloaded since
- did all the 'Malware Removal Steps' demanded

Symptoms:
- takes much longer than before to reboot, lots of hard disk activity; also playing the windows tune at reboot is interfered with lots of hard disk activity and doesn't play smoothly
- starting a web browser first time after reboot takes long
- before installing AntiVir got Windows Security Center warning about firewall being turned off, clicked the BALLOON and it appeared on
- before installing AntiVir did not get Windows update notifications (it's set to ask before downloading and installing), afterwards seen it twice showing 0% downloaded without asking for permission and then disappearing
- Spy Sweeper fails to contact its server (it's outdated, could that be the reason?)
- Spy Sweeper once said it blocked something trying to access spysherrif.com while I hadn't even touched the computer for a couple minutes; Firefox was probably open then
- Sysinternals Autoruns didn't show anything I would consider suspicious
- Sysinternals RootkitRevealer showed:
* HKU\S-1-5-21-1202660629-1844823847-1417001333-1008\Software\Skype\Toolbars\Firefox\ExtensionVersion
'mismatch between Windows API and raw hive data' - which I deleted but it came back
* HKLM\SECURITY\Policy\Secrets\SAC* and ...SAI*
'Key name contains embedded nulls (*)'
* Local Settings\Application Data\Mozilla\Firefox\Profiles\b3vfslns.default\Cache\...
many files 'Hidden from Windows API' and 'Visible in Windows API, but not in MFT or directory index' - I deleted all cache
- RootkitRevealer log files invisible (not hidden) on the desktop, even if 'Desktop' opened from Windows Explorer, only visible if 'Save' dialog box opened from RootkitRevealer and accessible via right click from there
- logged on under my partners account some hard disk and modem activity when idle and all unnecessary resident programs such as Messenger, Skype, etc. turned off, this didn't happen before
- 'Ethernet' light sometimes flashing on the modem when computer turned off, never happened before
