ESET using up all my RAM, please help in ESET NOD32 Antivirus Posted August 2 3 hours ago, Linxue said: Oh, and for some reason it´s using all my C drive capacity as well.....I´ve had almost 150TB written in the past week....that´s more that I´ve had for the past year.... And this is after having the computer turned on for maybe 6hours or so....nothing to do with start-up.... Try collecting logs and share here. Then uninstall ESET. 150 PB in a week? This is really hurting your HDD. On the forum I see another user also having similar high ram usage issue. Wait for ESET to find out the root of the problem, fix it and then install ESET again.
