Please forgive me if my account is garbled, I've been working on this problem for days now, while still working my usual job for the bulk of the day, so I'm a bit tired and everything is kind of merging into one alarming mess.
The setting - My girlfrined's Sony Vaio laptop, running vista SP2: an infrequently updated, overpriced, but very important piece of plastic. She is writing a novel. She has NOT been backing up her work (yes, I know what you're thinking, I thought it too and told her so).
What happened - (she was using it at the time, not me, so forgive me if this is not entirely accurate). She recieved an update notification, clicked to allow it, then there was some kind of security alert popup saying that the hard drive had failed. At this time her documents and desktop suddenly disappeared. I googled the alert and the symptoms and self-diagnosed a TDSS/Alureon infection. While I was doing this google redirects seemed to be operating too. I followed the instructions I found on Bleeping Computer to remove the infection, which did not work the first time, or the second, but appeared to the third (I think) when a boot time scan showed the trojan and allowed it to be treated. However, upon trying to boot after, the computer was unable to start. Startup repair attempts to repair the problem but fails, using both of the backups created by Avast! prior to the tinkering.
I managed to get the book onto a USB drive however there is a lot of other stuff on her computer that stands to be lost. I'm also concerned about the other computers on our home network, so am endeavouring to secure them as well as I can before I try to get the book off the USB that might harbour malware.
I have used TDSSkiller, Avast!, AVG, MalwareBytes, and SpyBot S&D, as far as I can remember.
Any advice would be much appreciated - I wish I had come here sooner but I thought I could handle this. I was wrong
