well i found this rather amazing! you know how you use programs etc. and overtime your free physical memory amount shown in ctrl+alt+delete shows as something lower than when your first booted the computer? well after i ran a full system scan with ewido, i was surprised to view my memory amount was back at its normal amount as if i rebooted. (it was originally 623mbs free previously without ewido running, went back to around 714mbs) also it raised my system cache from like 300,000 to 800,000. is this a bug/display error? or has it really restored that memory that's been used somehow?
