Um, so today i was playing MC as usual and all a sudden my Norton pops up and said; Threat detected: Trojan.semnager so the reccomended action was to restart my computer the security requests said restart now? i clicked yes. and when it was done updating,etc it said trojan.semnager: status: quarantined! so does that mean it can still infect my computer make it slow/laggy,etc?? @halothe23 @Lucariatias i really need to know if i should worry about it or no!
