You know what, I think you did lead me towards a good path there. I did realise something. I had rebuilt my website a while ago (it was in full php) now it’s in html. So in order not to lose this php content (“you never know”), I kept on storing in it in my ftp! Somehow Google still indexed it. I’m quite willing to bet (90% sure) that this Gumblar virus must have infected php as well (since I read somewhere it did). I don’t think I have the infected php folder somewhere still, but I’m quite willing to believe it was infected.
Now, in my Google webmaster tools, it seems that it still stores it in its cache – since I have some URL errors – saying it can’t find my php ones (normal since I deleted them recently).
So I’m going to proceed to a manual request to Google to forget about them and see what happens.
I do hope the martuz.cn domain is now dead as well, since I read that the gumblar one was.
Thanks for your help ! Cheers! I’ll let you posted as soon as our website is healthy!
