Hi BitDefender support,
My daily download traffic is cca 50-70GB. I download from servers like Rapidshare and Netload (no P2P networks). For downloading I use FDM (Free Download Manager) and JDownloader.
I used Windows Vista x64 and BDTS2009 before (with no problems). My problem started when I upgraded to Windows 7 B7600 x64 and BDTS2010.
The problem I'm experiencing is that after downloading cca 30-40GB amount of data, my memory is fully occupied (I have 4GB RAM). My system is completely unusable at this point. To be clear... dowloading cca 10GB costs me 1GB of my RAM.
To find out the cause of this problem (and to be sure that this is not a bug in Windows 7), I booted into safe mode and disabled "BitDefender Virus Shield" (VSSERV) service. Then booted back to normal mode and started downloading. After downloading 40GB of data, my memory usage was the same as when the windows started (cca 1.2GB). So the problem is gone with VSSERV disabled.
While downloading (with VSSERV enabled and disabled) my computer was idling, so no other process could have affected the memory usage.
Windows 7 B7600 x64
BiDefender Total Security 2010
RAM: 4GB
Thank you very much :-)
