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) |
- 防火牆(firewall)
- 安裝Windows的patch (Windowsupdate)
|
| 上網時不知／不小心安裝了軟件 |
木馬[城記](Trojan) |
- 防毒軟件:
- 除木馬軟件: 例: AD-aware
- 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 |
- 除木馬軟件: 例: AD-aware
- 防pop-up軟件:
|
| 電郵 |
病毒(Virus) |
- 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！

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)
