Hello,
All software, packed by PESpin (http://pespin.w.interia.pl/) is detected by BitDefender, as viruses. BD removes such software, when it is installed. PESpin is not a virus! It's just a software packer/protector. Can you remove PESpin from your blacklist?
For example I'm attaching one of our software products, which is detected, as containing a virus.
