I just scanned it and there are no viruses, And I also installed it on the backup site. Nothing mysterious is going on. I will keep everyone up to date about it if it acts up.
Yes It's a Stable Nulled. He use this version on his site and thousand of site running it. There is error found and no shell in it. You can use it. Thanks.
