Answer 1

Thank you Thomas in fact I have seen your guide before  and had gone thru the steps including repair disk which didn´t work. I am erasing disk before checking hardware. I have posted a photo of the 4 decrypted files in the disk utility and also of the adobe icons in the dock and question marks. Some people say if the adobe appears in the dock is because it is the trojan flash player and they keep jumping in the dock.  If this is not malware it seems to be an incredible coincidence that when I start seeing these things in my dock and the decrypted files in my disk utility is when my computer goes so slow (I am typing this in my macbook air because to write this message in my imac would be about 6 hours, I am not kidding, it is completely useless at this point it took me 2 and half days too instal mac os x after disk repair, it took me 3 days to transfer just 100 gigabites and now is taking the whole day (and it says another day more) just to erase the disk. Despite all this the icon of adobe keeps jumping in the dock so, although I am no computer and mac expert, just an user, I am inclined to think that it is malware and it is a shame that mac doesnt´recognize it or have anything here to help me get rid of this.  I am not even sure if erasing the disk will work since repairing didn´t work... all advice is welcomed.
