Did some googling and stumbled into this thread. I had the same problem. I tried with the usual scan for malwares, virus, tdsskiller etc problem still persist. I figured I tried the OTL solutions, I know that my system is different and I don't really know how OTL works so I put 2 and 2 together until the log says my system is clean from Claro. I succeeded in that but each time I open Firefox the home page still redirects me to this damn link. What am I doing wrong? Can anyone help? Here's my OTL.txt too. Edit: Did another OTL scan, it reappeared. This happened before, did the same steps, it was gone, opened Firefox and then reappeared again! Need help, please advise. Updated the OTL.txt.
