Your HijackThis log doesn´t indicate IMO any problems. And I think you should
STOP using pirated software over and over again. As you see, it results in problems and more problems... AV and anti-spyware tools are not a Panacea...
If you reformat the whole disk while installing XP, yes, you will loose the hidden recovery partition. I believe though that it´s possible to keep it if one sets the partition for XP before starting the installation to keep the hidden partition (then you install XP on the same partition thus preserving the recovery one). However, one needs the predesktop area to access the hidden partition and I really have no idea if it will be preserved or remain bootable...
The purpose of the recovery partition is to (custom-)restore the factory contents of your laptop. For that purpose one has to boot in the predesktop area by pressing the blue ThinkVantage button after powering on the machine, then one is presented various restore options, one of them is restore to factory state.
I don´t know if SP3 was officially included in the latest installation media of XP, but one can slipstream SP3 into an XP installation by using a program called
nLite. In the end it will create an iso image of the XP installation that you will have to burn on a CD
as image. However, you will need some XP installation media as a source for the main files. I think the easiest way for you to apply SP3 would be via windows update. And please don´t use the pirated custom modified versions of XP with SP3 included available as torrents. Many of them include security holes or malware within the installation on purpose!
You can find all the ThinkVantage software and all Lenovo XP drivers on Lenovo website under
support. Also, depending on what you are going to install, you will need to keep some order of the installations. Alternatively, if you still keep the recovery partition, you can perform a custom-restore of the factory contents, so you can keep only those Lenovo programs you really need. It´s pretty automatic, so you don´t have to watch it. However, if you decide to go for a clean XP installation, you may want to use System Update. It will find all drivers and programs needed for your ThinkPad, then you can select which ones you want to install.
As a last resort for your virus problems, you can try out
AVG 8 free. I don´t like it as much as my AVG 7.5, which unfortunately is nowhere available for download. But I believe AVG 8 still shares some of the good features of AVG 7.5 (well, it´s somewhat slower and produce bloated feeling...) You will have to uninstall NOD32 and other AV software if you have some (you shouldn´t have more than one AV installed (!) ), you can keep spybot and spydoctor though. For your sake I hope AVG will find something...
Cheers,
Marin
