Vista - Vista deleted my profile files and many other

Hello,

Something unbelivable just happend today to my Vista 64 Ultimate. I was logged into it and just wanted to start world of warcraft to play a bit. when i started it i just received some message telling me the game cannot authenticate me coz of the lack of some needed files. I opened the warcraft folder and almoust all the files from its root were missing. Then rebooted the computer but vista failed to start as i was receivin some Boot/BCD error 0xc000000f. I used the repari from vista dvd and i finnaly repaired the boot but when i was about to logg into my account this doesent want to load...my account profile files are completly gone....all of them ...desktop shortcuts, downloads etc evereything. Now im logged into somtype of temporary profile and i dont know what to do...system restore doesent want to start either.
i use bullguard antivirus updated every day which showed no sign of virus etc...im not a newby in computers and i know very well what can get me into trouble with viruses, trojans, malware etc and im 99% sure i didnt got any ...
i really dont know what to do in this situation....i also dont know what files im still missing more....since as i said not only vista files where missing but my WoW file located in completly another folder and also all my downloads documents everything from my profile...
i have 3x500gb HDD mounted in RAID 5...the raid its healthy with nothing to worry about....

please help me
Thank you

Hi Ger0nim0,

You might see if this tutorial can help with the temporary profile error.

Hope this helps,

i finally managed to run system restore and i restored the system to an earlier point.
I got most of the files back, but still the system its behaving abnormally...firefox doesent want to start...even after reinstall...WoW keeps telling me about some corrupted files, my vide surveillance program stopped working as intended and i think i will discover more...anyway, does anyone know what should i do to fix this or at least to prevent from happening again?

thank you

From the sounds of the problems you are still having, I would recommend a clean reinstall of Vista. Be sure to backup what you do not want to lose if possible.

I'm not sure what may have caused the problem to begin with, so I cannot offer any advice on how to prevent it from happening again. My guess is some form of malware.

Hope this helps some,
Shawn
