Kaspersky Red Alert for 3DP Net

Kaspersky reports an infected file on 3DPNet

i am a computer technician here in paris

and a tool like this is an invaluable help for me

i repare many old machines and if it can help detect drivers

...but it seems that 3DPnet is infected with a trojan.backdoor win32.poison.bkfa

Is it a false alert ?

Normally i trust Kaspersky this is my only protector

but i see in your forum that false alerts occured with AVG some months ago

it's maybe the same kind of problem.

Thanks to verify and tell what you think.
