Hey guys, a close friend of min installed Roboscan free version about a week ago. Well I told him that the site and program hasn't been updated since 2013. He told me that he knows that the program has not updated but the virus definitions are updating. It uses the Bitdefender engine and its own Tera engine . Do you think it's safe to still use this program, or can you recommend another free AV that is good but also lightweight. Thanks.
