Well my english is not that good but i hope all you guys understand me, that´s what i got, an empty screen on my desktop since i finished the install process of avast 7 from 6, i though my computer was still loading something but un hour have passed and still any icon appeared so i had to turn off/reset the machine from the button, when i turned on again, the same, nothing on my desktop again and again, at this point i was getting really upset and then i could run my computer into safe mode and tried the recovery and it worked but avast was totally corrupted, i couldn´t uninstall it in any way, and i tried the uninstall tool from the official avast page asw cleaner i think, in safe mode(it´s very important to run it in safe mode, otherwise it doesn´t work, and then avast was totally erased from my computer, then download avast 7 free from the official page, registered again, and it´s working perfect now, i know it´s not that good from the avast team to free this version to download harming our pc´s, even if it´s free, (cuz the loss could be a lot big) and without warning about, or sending apologies to the users, but i hope they take care more into further vertions, i'm still confident to avast cuz i used it since the 4th version, long live avast!!!
