It's a file hosting site, and I have not encountered anything suspicious. Just use common sense, if what you're downloading is software, make sure that you trust the vendor. Alfafile is merely a host. The only reason to exercise caution in child safety is that any content can be hosted here, uncensored. Again, no different from any other file hosting site.
Alafile is a cloud based storage service. Similar to rapidgator and nitroflare. As with most of these cloud storage sites, uses store files that may be adult in nature and/or copyright infringement. Be cautious when downloading as the shared files maybe adult in nature therefore children should be cautious in downloading files. There are No viruses, adware/ spam o be concerned with. I've used this site for the past 5 years.
Another illegal cyberlocker site using non nominated directors to appear as a UK company Farnboro LP but who won't pay any UK tax due to their secret ownership. Details of this company have been passed to Europe.
July 2017 Update. Farnboro LP have changed their address to another mail forwarding address at 5 Rubislaw Terrace, Aberdeen, AB10 1XE. There are over 500 companies registered at the same address, an indication perhaps of exactly the kind of companies who need to hide their details?
UK law now states that all limited partnerships need to declare all officers of the company including 'Persons with significant control' and yet no persons are listed at Companies House.
