Great AV, lightest of all. Effective of all. I just can't believe how light they made this AV. I was with microsoft security essentials for almost 6 years, and have not used any other AV or MV softwares before but i recently heard about ESET thought i might give a try, at that moment when i uninstalled MSE my pc was so much faster. Days later i purchased the 2 years license of ESS. Thanks for the review OP!
