是駭客入侵嗎？防火牆log紀錄大到327KB

這是我的防火牆的紀錄：

這樣子的紀錄該不會是指：我被裝了木馬吧，
這是我沒有用網路的狀況下哦，竟然還一直向外送資料，
不只是137port 139也有，才三天而已，
我的防火牆 log 紀錄檔已經有300多kByte了
前陣子還有一件可怕的事發生，我都沒有上傳東西，
可是電腦卻一直在上傳，重新撥接後也一樣。
Ps. 我是用中華電信ADSL 512/64
Windows98SE
Tiny Personal Firewall
沒有任何即時通訊軟體(就是icq, messangers那些)

剛剛我又發現靈異現象：

1,[2001-Jun-20 19:44:12] Rule '137 Port Interruption': Blocked: In UDP 61-216-42-180.HINET-IP.hinet.net [61.216.42.180:137]->localhost:137, Owner: SYSTEM

中間有些部分因為太多了，所以我就切掉了。
上面的61.216.42.180就是我自己耶，這是怎麼回事
