I think I have the same problem as Holtzz ( 13 - 12 )
My homepage also keeps changing to www.vroomsearch.com, links are added to my Favorites.
I followed all the instructions, did a hijackthis. scan and log.
I removed the files with the word vroomsearch, but it was not efficient enough.
Probably I have to remove other files to?
Can you help me with this problem.
I attached the hijackthis.log file.
