Whenever i download more than 6 or 8 files simultaneously the ram usage begins to rise till reaching full capacity. My system has 2 GB of ram and after downloading for 1:30 - 2:00 hours the ram fills up reaching 1,95 GB and my system becomes unstable. The weirdest thing is that when it reaches full capacity the system doesn't see my NIC anymore and the connection drops. Even when the download is over the ram usage doesn't drop and the only way to empty it is to restart the PC. I tried to remove the antivirus and it worked, the problem didn't occur anymore. I love ESET is the lightest anti virus I've ever had but it can get very heavy at times i hope you will fix this problem. P.S. I'm running windows 7 but i have the same problem on vista.
