Randomly NOD32 2.7 and Eset Smart Security starts blocking popular ports. At first, I thought it was only HTTP, but today I noticed that it does that for FTP as well. IRC works. BitTorrent works. This only happens when I have an ESET product installed. I don't know why this happens. But, you cannot regain http access until you restart the computer. It's quite annoying. This is not firewall related because it works with NOD32 2.7 as well. It could be a driver issue. Regardless to say, I don't know what to do about it. So, I have uninstalled both the NOD32 trial and Eset Smart Security Beta 1b. I'm on Vista.
