X的.....我有回,結果那時候網路斷掉,我以為PO了 @@

這樣吧,你先把檔案上傳檢測: http://www.virustotal.com/xhtml/index_en.html
確定是否有毒~

dat檔大部分是記錄檔,例如history.dat 或 NTUSER.DAT.....是病毒的機率不大
至於防毒軟體大多講檔案鎖定(locked) 密碼保護(Password Protected)....等就不用理他了

至於是否為木馬就難判斷了,可以用spyware軟體掃,不過老實說這種軟體的效果不大,頂多對付一些cookies,已知的老木馬~~等,木馬還是要依靠防火牆~

上面是我測其中一個檔案所出現的結果(英文很爛，請看懂的大大幫忙翻譯一下)

那這樣是有問題還是沒問題阿

沒問題啊.....所有的防毒軟體都沒反應.....你看看NOD32說密碼保護....別理他...

所以OK啊,這些檔案是無毒的,就放著吧~
