【討論】BD病毒庫減少了2萬多??

[esjustin]

BD威脅資料庫是確切有48萬以上的,就連AntiVir也已經破52萬了...你說難道AntiVir在Virus.Gr的測試成績並沒有很高..那它的威脅資料庫是在虎濫囉?

那BD的威脅資料庫是包含甚麼?從它對威脅的命名就可以知道了:http://www.bitdefender.com/site/Naming-Conventions.html

減少可能包含:誤判刪除,修正重複資料,資料整合等...

實際情況還是要詢問BD公司...

拋棄過去的DOS下的代碼庫是比較理想的增加掃瞄速度的做法。

Kaspersky依然沒有捨棄DOS時代的威脅碼...

BitDefender 原廠對定義庫減少的的說明

1. 不會對偵測病毒數有所影響
2. 整理病毒定義庫將一些 報出病毒名換成通用名故減小病毒數
3. 減少記憶體的使用
4. 執行日期 11/1/2006

ISSUE:
This article describes the BitDefender update on November the 1st, 2006.

SOLUTION:

An update to the BitDefender signature database file was performed today, November the 1st, 2006 resulting in a decrease in the number of signatures listed. The number of viruses detected by BitDefender is NOT affected.
A number of signatures which each matched a single virus variant have been replaced with generic signatures which match entire viruses families. This leads to lower memory consumption by 3 to 4 MB and a smaller size on disk (by 2-3 MB) for all BitDefender products.

BD還真有時間可以整理威脅資料庫啊...

[ㄚ一]

BD還真有時間可以整理威脅資料庫啊...

Kaspersky每個周末都會整理病毒庫

BD還真有時間可以整理威脅資料庫啊...

對壓，小天才還要唸書，將來考上名校
另一方面還要常常在此領導大家觀念，小兔子還是覺得小天才時間運用效率最高呢

[tulipa]

BD的病毒庫似乎有濫竽充數之嫌,人家卡巴斯基對已知病毒的偵毒率比他高,病毒庫也只有23萬而已

感覺 hn1271n 哥哥 說的話話，很有道理和蘊含人生智慧
防毒軟體如果病毒庫過多，那一定是用濫竽充數的方法，來欺騙世人，盜世欺名

[esjustin]

為何Kaspersky病毒庫比別家少,偵測率卻奇高?

因為Kaspersky多收集的是近幾年的威脅...從前的DOS時代的威脅少有收集...

所以新的比舊的多...偵測率會比那些舊的威脅碼很多的防毒產品還好...
