Hello everyone,
I just installed BitDefender Internet Security 2010 on my freshly installed Windows 7 Pro 64bit, but the firewall module of BDIS is blocking Windows Update from downloading updates.
I have checked this issue by turning on/off the firewall while trying to download updates. Around 2-3 seconds after disabling the firewall modules, the download starts/resumes, turning it back on makes it stop (well, currently downloaded update installs, then says unable to download remaining updates).
The firewall is set to default (Allow Known), I set it to Report but it failed to report anything about Windows Update. I don't see any rules blocking Windows Update, however I don't know what process to look for, since AFAIK it's a service running inside svchost.exe.
I hope to get some help from you guy
