hello . my computer became very slow and was acting erratic at times. i called apple they took over my computer and scan my computer some how . the zues malware was detected . they also showed me logs where un authorized persons where compromising my machine. then they said they will fix it but only if i purchase apple care for lifetime 399.00 i don't have that kind of cash right now . so either I'm going to attempt to remove this myself or just keep this computer offline until i can save for the funds. if anyone is familiar with this problem. i sure cold use guidance as i am not versed in this area.
