Avast 5.1 已可直接更新上 Avast 6.0.1000

已經可以用 Avast 5.1 內的程式更新直接升級上 Avast 6.0.1000，但官方論壇還未有 6.0.1000 的 release note。

Avast 6.0 beta 試用

Avast 6.0 已推出第二版 beta，修正了第一版大部份的臭蟲，便下載來試試。

Avast 6.0 免費版也加入不少新功能或強化了原有功能，官方公佈如下︰
- AutoSandbox – suspicious programs will be optionally run sandboxed
- avast! WebRep – browser plugin for website reputation rating
- Script Shield now even in the Free AV
- Site Blocking now even in the Free AV
- Restore factory settings command (Settings -> Troubleshooting)
- Automatic actions in the boot-time scan
- New compression method in the installer makes the setup packages about 20% smaller.
- Script Shield now functional even with IE8/IE9 Protected Mode
- Sidebar gadget
- Improved stability/compatibility of the Behavior Shield
- Improvements in the avast! sandbox

注意安裝 6.0 前要先移除原有 5.x 版，安裝時已提供繁中選項，安裝後也如前版要程式註冊。

新版介面並沒有大改變

免費版加入了原付費版有的腳本防護功能

其他防護下可以找到 6.0 的新功能-全自動沙盒、網頁信譽評價及站台封鎖

全自動沙盒

網頁信譽評價

部台封鎖

新的全自動沙盒會將可疑的應用程式開啟時自動移到沙盒內執行﹐不過預設會有警告示窗彈出，詢問用戶是否確定程式在沙盒內執行，若是用戶已知的安全程式，可以選擇不在沙盒內執行。

沙盒警告示窗

用戶可以在警告示窗勾選記住程式的沙盒設定，也可以在沙盒的設定視窗加入排除檔案。

自動沙盒只提供簡單的設定

網頁信譽評價會在瀏覽器的工具列上加入小圖示顯示正在瀏覽的網頁是否安全，按一下小圖會彈出評價視窗讓用戶反影對網頁評價，可以看到這部份還未中文化。

網頁信譽評價視窗

新版也提供桌面小工具，不過用處不大，功能似乎跟原有小圖示重疊。

桌面小工具

試用感想
1. Avast 6.0 維持原有佔用資源少及不大影响電腦效能的好處
2. 免費版可享原有收費版的功能，防護有所加強
3. 個人一直以 Comodo 防火牆配合 Avast 使用，Avast 新版的沙盒及加強了的行為防護跟 Comodo 的功能有所重疊，試用時 Avast 沙盒內的程式可用性似乎比 Comodo 沙盒差，Avast 沙盒中的 Q-Dir 就不能抄擋案，Avast 的白明單似乎也比 Comodo 的少，所以之前試用行為防護時有些不必要的彈窗，所以個人選擇不安裝 Avast 的行為防護，不過也可能是本人常的程式比較配合 Comodo，用戶可以自行試試那一個程式的沙盒及行為防護會較合用
4. 試用了一天，beta 版暫時沒有特別問題

Frequently Asked Questions(FAQ)

A - Only the setups are released as of today(12/29/2010). We will be issuing the updates next week.

Q - Should I uninstall CIS 5.0 and reinstall CIS 5.3?
A - You dont have to. You will get the update next week anyway. But if you dont want to wait, you can.

Microsoft Security Essential 2.0 正式推出

微軟正式推出了 Microsoft Security Essential 2.0，MSE 第一版的口碑只是一般，但看過網上一些對 2.0 的前期測試有不錯的評價，說是加強了 IE 及 Windows 內建防火牆與 MSE 的整合，使他對用戶上網時有更強的防護，據聞新版也加入了類似智能行為防護的功能。

電腦玩家有編詳細的介紹，我就不在這裡多寫了。

金山毒霸

金山最近也加入了免費防毒軟件的行列，本來在虛疑機上試用可牛，但可能因主機上的防毒有網絡監控或是和虛疑機不夾，所以不能自動更新，那就正好試一試金山毒霸。

金山毒霸在一些測試報告上的病毒偵測成績並不出色，但它的效能及資源佔用表現上卻十好，那正好配合防護力較強的 Comodo 防火牆使用。

安娤毒霸時會警告軟件只適用於大陸及簡體視窗，但我安在繁體視窗上也沒有大問題，只是其中一個非主要功能頁面出現亂碼，而且也可以用 Applocale 解決。使用上暫時沒有發現問題，也真的很省資源，希望它能加強查殺能力，說不定未來主機也會轉用它。

官網介紹

What's New In COMODO Internet Security 2011?

THANKS! COMODO would like to thank the beta testers whose feedback made this release possible!

NEW! Extended spyware scanner and improved malware cleaning
NEW! Cloud Based Antivirus Scanning
NEW! Cloud Based Behavior Analysis
NEW! Cloud Based Application White-listing
NEW! Game Mode
IMPROVED! Application Control
IMPROVED! Default Deny re-engineered to improve application compatibility
IMPROVED! Application user interface

Cloud Based Infrastructure:

2011 family of products(Yes COMODO Firewall too!) are now armed with cloud based file rating technologies. The cloud computation, enabled by default, is used for a variety of purposes.(Do not be surprized if COMODO Firewall gives you a malware alert!!!).

With cloud computation;

Cloud based Whitelisting: Safe files and trusted vendors are now easily identified. The concept of “Trusted Publisher” is now cloud based.

Cloud based Anti virus: Malicious files are detected even if the users do not have an up-to-date antivirus product or an antivirus product at all.

Cloud Based Behaviour Analysis: Zero-day malware can be detected INSTANTLY by COMODO’s cloud based behavior analysis system CIMA(Comodo Instant Malware analysis).

Extended Spyware Scanning

COMODO’s vision and focus has been about “keeping a clean computer clean” from early days. Now that We have achieved that COMODO is focusing on “cleaning an already infected computer”. This is why we extended the spyware scanning in COMODO Internet Security 2011 and COMODO Antivirus 2011 and now include a new spyware scanner which is capable of scanning the windows registry and computer disks for the signs of malware infection.

This new scanner is implemented to improve the detection and successful cleaning rate of already infected systems.

Game Mode

2011 family of products are now gamer friendly security applications. When they are put into the game mode, the operations that can interfere with users’ gaming experience such as alerts or resource intensive virus database updates, scheduled scans are suppressed.

Stronger and Smarter Application Control

2011 family of products have a highly smart application control mechanism which extends the functionality of the previous versions.

The new application control provides the users the ability to lockdown their computers such that only the known good applications can be executed.

The new sandbox introduces a new default application isolation level, partially limited, which improves the compatibility with many windows products.

Nowadays, a lot of malware come in other forms than standalone executables. For example, some come in the form of visual basic scripts while some come in the form of java binaries. When they come in such forms, they are executed by “interpreter” applications such as wscript.exe or java.exe etc.

2011 family of products can identify such applications heuristically and detect the real file behind the requests of “interpreters”.

Comodo Internet Security 5 beta (更新至 5.0.158836.107)

Comodo 推出 CIS 5(或稱 CIS 2011)測試版，試用了一下，介面作出了較大改變，但主要操作方法沒有太大改變，舊用戶應該不難適應。

COMODO Internet Security 5.0.156985.1061 BETA Released

已經有人開始制作繁體中文語系檔案

官網介紹
NEW! Application Whitelisting
CIS 5.x fills the missing links that its predecessors had in this area by providing a usable application white list control.

NEW! Spyware Scanner and improved malware cleaning
CIS 5.x again fulfills the missing features of its predecessors by providing a new spyware scanner which is capable of scanning the windows registry and file system.

Note: We will be releasing the signatures for spyware scanning during the course of BETA testing. So you might not immeidately see this in action. i.e. next monday

NEW! Cloud Based Antivirus Scanning
CIS 5.x has integrated the cloud based computation everywhere. From on-demand scanning to process execution control, it checks if the file is known in the cloud.

NEW! Cloud Based Behavior Analysis
Instant malware analysis has been introduced to CIS 5.x making detection of unknown malware possible! Any unknown file that is sandboxed and NOT observed by COMODO before is submitted to CAMAS and results are sent to the PC in 15 minutes after the upload process is done.

NEW! Game Mode
Now CIS has a game mode. Just before you start to play a game, you can switch to game mode and all the alerts will be suppressed. Virus database updates or schedules scans will also be postponed.

IMPROVED! Default Deny re-engineered to improve application compatibility
Unlike CIS 4.x, CIS 5.x, by default, automatically runs every unknown executable as "Partially Limited", which is a new level introduced with CIS 5.x.

IMPROVED! A New User Interface!
You will be seeing a lot of suprises with the new user interface. It is friendlier, easier and prettier.

可牛殺毒

可牛殺毒現時還是測試版，雖然只有簡體版本，除了在安娤時出現亂碼，安娤後在繁中視窗中也能正確顯示。可牛殺毒背後應用的技術不錯，令人期待﹔

• 雙引擎-卡巴掃毒引擎+金山雲
• 有IE保護、網頁及釣魚網站防護
• 有電郵防護、關鍵位置防護
• 有主動防護
• 提供不同的専殺工具
• 不過修復漏洞功能在繁中視窗不能使用

教你如何減少 Comodo 防火牆 Defense + 的警示

Comodo 防火牆功能強大，雖然版本4已減少了很多警示，但還是有許多人特別是初用者都嫌它有太多的警示，有人建意關閉 Defense+ 功能，但這差不多廢了 Comodo 的防護能力，個人並不贊同。

其實 Comodo 本身也提供了下列一些方法幫你減少 Defense+ 的警示﹔

1. 我的安全檔案
Comodo 內建了一份安全檔案清單，執行在清單內的檔案時只會有極少的警示，因內建清單只包括一些較流行的程式，用戶可以自己在 Defense+ 的一般設定內，把常用的程式加到"我的安全檔案"清單中。若檔案有軟體商的數位憑證簽章，個人會建議用方法2，因這樣可讓 Comodo 識認更多安全檔案。

2. 我的信任軟體商
Comodo 也內建了一份信任軟體商清單，若檔案是有信任軟體商的數位憑證簽章，便會當為是安全的檔案，用戶同樣可以在 Defense+ 的一般設定內，把常用程式的軟體商加到"我的信任軟體商"清單中。

3. 使用"乾淨系統模式"
若你確定電腦現時沒有感染惡意程式(包括你已下載的安娤檔)，你可以使用 Defense+ "乾淨系統模式"，這樣現存硬碟上的所有程式都會視為安全的檔案，而 Defense+ 只會監視啟動"乾淨系統模式"後新安娤或下載的程式。

4. 暫時使用"學習模式"
若你的電腦一向沒有問題，你可以用 Defense+ "學習模式"幾天自動建立 Defense+ 的安全規則，再返回安全模式以減少警示，當然使用學習模式時會失去 Defense+ 的保護功能，所以我自己較喜歡啟用學習模式後隨即執行所有常用程式一次，然後立刻返回安全模式。
