Grecale,
why don't you tell the people on the forum what your problems are, how you installed Avast! 5, and a bit about your OS and other security software, and maybe someone can help you with your problems. Since you show you have never posted before, looks like you never asked for help either. As far as F--- yous, threats, and requests for money back, you will need to get in contact with Avast! during normal business hours to sort that out. Most of the people on the forum are just other users who have broken enough stuff to have an idea of how to fix things. Some of them even speak Italian if you get desperate.
Thanks for the answer, since happned 4days ago.............
Two pC , windows xp with avast 4free, spybot, same configuration, one is in office and the other is notebook
I bought update 3 licenses to avast5 internet security , download the exe and the file for licence, start the programm and crash after few second, no more signal allblack......
Unlucky while i update mine the office make the same, this time two crash after that allblack too
And now what you think i feeel myself? of course i had a backup dates but not all, not all
For me there is no story, the software is very dangerous, every machine worked well without problems before the update
The security test is durty water without sense, they are selling a dangerous product
Thank to hear me
