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

防截鍵及螢幕軟件 SpyShelter Personal

截取鍵盤記錄及螢幕是間碟軟件偷取電腦戶私隠的方法之一， SpyShelter Personal 的主要功能就是防止不明或沒有許可的程式截取鍵盤記錄及螢幕，此外它還可防護剪貼簿及有簡單的 HIPS 系統保護功能。

SpyShelter 提供的保護 (免費版不包括攝設備、錄音及網路間諜保護)

可以自動或手動設定黑/白名單

SpyShelter 其實是有點像 Comodo 的主動防禦，所以開始時也會有不同的詢問彈窗，用戶也可以設定自動功能讓 SpyShelter 自己決定是否放行程式，但用戶可能要手動修改沒有被自動放行的程式。

雖然已經裝有 Comodo，但 SpyShelter 最大的好處是防截鍵及螢幕軟件的功能比 Comodo 強，所以同時安裝使用。

官網介紹

SpyShelter uses special algorithms to protect you and your data against:

* Spy and monitoring software that are used to steal or reveal your data to other parties.

* Extremely dangerous and custom-made keyloggers that steal information you send via your computers- these are favorite tools of cybercriminals.

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。

兩個加強 Firefox 瀏覽安全的附加元件

LinkExtend
當我們用搜尋引擎來搜尋網站後，搜尋引擎並不會告訴我們這些網站是否安全、是否值得信任，某些防毒軟體雖然提供了網站過濾功能，但是由於網站內容更新速度快，不見得能夠完全過濾掉不安全的網站。

LinkExtend 是能夠用六種網站檢查引擎來過濾網站安全的 Firefox 擴充套件，讓你在下載檔案前能預先知道該網站的安全指數，再來考慮要不要從該網站下載檔案。

搜尋結果會附加網站的安全指數

VTZilla
之前也介紹過 VirusTotal 網站，該網站內建了超過四十種掃毒引擎，只要上傳一個檔案(最大20MB)就可以檢查是否帶有病毒。如果你想在下載前就先讓VirusTotal來檢查的話，可以安裝VirusTotal所提供的 Firefox 檔案掃描擴充套件–VTZilla。

SUPERAntiSpyware 綠色版

SUPERAntiSpyware 是一個類似 Malwarebytes' Anti-Malware 的反間碟軟件，網上有測試它在惡意程式的偵測率比MBAM 低，但它能掃描到一些 MBAM 遺漏了的惡意程式，因此可以配合使用，而且 SUPERAntiSpware 更有綠色免安娤版，免費版提供的功能也比 MBAM 免費版多，可惜一點的是它沒有繁體中文，用簡體又會出現亂碼的情形。

Previx SafeOnline 上網安全軟件 (更新至 3.0.5.199)

如之前的 KeyScramber，Previx SafeOnline 能加強上網隠私的安全，能防止截屏、防截鍵盤記錄、掃描及移除惡意病毒、及防護惡意程式。它最大好處是易用，不如 HIPS 般要用者正確回應警告才能防護電腦，而且它不用特徵碼而是用雲安全技術，所以和其它防毒軟件沖突的機會很少。

不過它有一個弱點，就是當第一次開啟其它應用程式時，它都會用雲安全檢測載入的程式是否安全，並等待雲安全的結果才會讓程式啟動，這樣就拖慢了程式的啟動，不過之後再開啟同一程式時便不會再有明顯拖慢的情況。


現在 Prevx 和 Facebook 合作提供免費 SafeOnline 特別版（永久免費，但是沒有了移除病毒及即時防護惡意程式的功能）。這圖可以看到惡意程式移除及即時防護要購買才可啟動 (它把我的 AntiTest 測試程式當是惡意移式)

如一般防護軟件的基本設定

進入 SafeOnline 功能設定，在這裡可以加入要受特別隠私保護的網址及設定安全的強度

這裡有其它工具選項

官網介紹
To protect information being stolen while browsing on an unknowingly infected PC, we developed Prevx SafeOnline. Prevx SafeOnline will protect your information entered in or displayed by your Internet browser, by locking down the operating system and services to ensure that only "known good" processes and services are allowed to run.

ClearCloud DNS 惡意網站防護

之前文章從最根本開始做網路防護介紹了幾個免費的 DNS 服務，但都不能防護惡意網站，或是要付費才可以，但這個由 Sunbelt Software 推出的 ClearCloud DNS 就免費提供阻擋惡意網站的功能，網上有測試顯示暫時它能識別的惡意網站只是一般，可能現在還是測試版，不過旣然不佔用任何電腦資源，也能阻擋部份惡意網站，在使用上也沒有發覺延誤，所以自己也就即時採用了，希望正式推出時它能有所增強。

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。

似乎內建白名單也加大了，一些以前認不出的程式現在也能自動識別，使用上更方便。

可牛殺毒正式版已經推出

之前也有介紹可牛殺毒，昨天終於推出了正式版，正式版上加入了下載防護及更多専殺工具，也通過了 VB100 最新八月的測試。

個人覺得可牛是簡化了的"卡巴+金山衛士+網盾"的混合體，較其它免費殺軟最大的分別是包含較多的上網防護功能，如防網頁掛馬、防釣魚網站、瀏覽器保護、瀏覽器修復等，並內建専殺工具下載。(註:修復漏洞只適用於簡體 Windows)

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.
