電腦保安問題

Computer Security Problems

因為這些網上惡勢力越來越利害,使不少人中招,所以本人加了這頁使大家加強防範.

中招途徑
一般分類或相關
例子&解決
上網(它不必用任何啟動機制) 蟲(Worm)
  1. 防火牆(firewall)
  2. 安裝Windows的patch (Windowsupdate)
上網時不知/不小心安裝了軟件 木馬[城記](Trojan)
  1. 防毒軟件:
  2. 除木馬軟件: 例: AD-aware
  3. 防pop-up軟件: 有些木馬是會以pop-up出現,當你不安裝時,它卻會安裝.說實,你在那個pop-up box 中選任何的button皆會安裝的.〔我會不理它,直接關browser.]
上網或其他時間裝了不知來源的軟件 adware, spyware, scumware, homepage hijackers, diallers
  1. 除木馬軟件: 例: AD-aware
  2. 防pop-up軟件:
電郵 病毒(Virus)
  1. 防毒軟件

若要安全,就要一Up四防:一要時常做WindowsUpdate. 四防:是防火,防毒,防馬,防pop-up.

為甚麼沒有簡單的解法?

不少人會以為遇上這種問題, 以為只要一個簡單的方法, 就可以解法.但若果你細心分析一下微軟的解決方法(它也出過多個不同的步驟),及其他公司有不同的方法,就會明白.根本沒有一個必定的解救方法!

Computer Security Alert!!!

    1. 特別介紹:香港電腦保安事故協調中心
    2. 保安漏洞:用Microsoft's Internet Explorer (IE) v. 5.01, 5.5, 6.0 皆有此問題. (20/8/2003)
    3. 保安漏洞:所有Microsoft's DirectX 5.2, 6.1, 7.0, 7.1, 8.0, 8.0a, 8.1, 8.1a, 8.1b, 9.0a 皆有此問題. (20/8/2003)
    4. 保安漏洞:Microsoft Data Access Components (MDAC) Security Patch MS03-033 - 繁體中文:直接下載;MDAC v. 25 -27皆有此漏洞.
    5. 答客問:病毒通知: W32.Blaster.Worm: (包括去除病毒的方法圖解; 中文的!)
    6. 直接下載防這個worm的patch:繁體中文 Windows: (即 中文Microsoft Security Bulletin MS03-026)
      1. WinXP;
      2. Win 2000;
      3. Win NT 4.0;
      4. Win Server 2003.
    7. Your computer is not vulnerable to the Blaster worm if either of these conditions apply to you: 以下的電腦不會中這種蟲:
      • If you are using Microsoft Windows 95, Windows 98, Windows 98 Second Edition (SE), or Windows Millennium (Windows Me). 以上的視窗版本不受影響.〔但留意剛出現一種利用同一弱點的蟲,針對Wind98, 95, Me的.是W32.Randex.E.去除法是下載這檔案,並執行之.]
      • If you downloaded and installed the security update that was addressed by Security Bulletin MS03-026 prior to August 11, the date the Blaster worm was discovered. 在八月十一日前已安裝了MS03-026的Patch.
    8. 快到 W32.Blaster.Worm // Removal Tool // Microsoft security // Firewall: ZoneAlarm ;(direct download); others FREE firewalls.
    9. Please note that Blaster does not affect Win 98, Win Me, or Win 95; but another worm with similar property will: W32.Randex.E is an Internet Relay Chat (IRC) Trojan Horse that allows its creator to control a computer by using IRC. It is also a worm that can use the DCOM RPC vulnerability (described in Microsoft Security Bulletin MS03-026) to spread itself. Remove the W32.Randex.E Worm use this VBS.
    10. Beware of ‘Parasite’! They have attacked my computer secretly when I use the internet. I found them ONLY after a spyware scan! Parasite is a shorthand term for “unsolicited commercial software” — that is, a program that gets installed on your computer which you never asked for, and which does something you probably don’t want it to, for someone else’s profit. REMOVE these adware, spyware, scumware, homepage hijackers, diallers, by FREEWARE (Ad-aware)
    11. Microsoft reveals 'critical' flaw : affecting all versions of DirectX from version 5.2 to the current 9.0a (Win 98 to Win server 2003)! : Patch
