Comodo Cleaning Essentials 綠色掃毒軟件

Comodo 的防火牆比較出名，他也有防毒但就沒防火牆的好用，但他的綠色掃毒 Comodo Cleaning Essential 似乎就比他的防毒出色，在最近在 PCMAG.com 的清毒測試中還得到 Editor's Choice。

Microsoft Standalone System Sweeper

另一隻 Microsoft 推出的掃毒工具給中毒後不能正常開機時用，現在還是測試版。

官方介紹
Microsoft Standalone System Sweeper Beta is a recovery tool that can help you start an infected PC and perform an offline scan to help identify and remove rootkits and other advanced malware. In addition, Microsoft Standalone System Sweeper Beta can be used if you cannot install or start an antivirus solution on your PC, or if the installed solution can't detect or remove malware on your PC.

Microsoft Standalone System Sweeper Beta is not a replacement for a full antivirus solution providing ongoing protection; it is meant to be used in situations where you cannot start your PC due to a virus or other malware infection.

To get started, please make sure that you have a blank CD, DVD, or USB drive with at least 250 MB of space. Next, download and run the tool – the tool will help you to create the bootable media required to run the software on your PC.

Microsoft Safety Scanner

Microsoft 官方出的綠色掃毒軟件。

官方介紹

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

Dr.Web® LiveCD

之前介紹過用 Avira AntiVir Rescue System 為不能開機的電腦清理病毒，Dr.Web 也有提供 Live CD 下載幫助不能開機的電腦清理病毒。雖然 Dr.Web 的病毒偵測率可能比 Avira 低少許，但有測試顯示它有較強的清毒能力。

Dr.Web 只提供光碟 ISO 檔，所以下載後要用燒碟軟件把它燒制成開機碟。

官方介紹

If your Windows or Linux system has been rendered non-bootable by malware, restore it for FREE with Dr.Web LiveCD!

Dr.Web LiveCD will clean your computer of infected and suspicious files, help you copy important information to a removable data storage device or another computer, and then attempt to cure infected objects.

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。

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。

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。

AVG Anti-Virus Free Edition 10.0（2011版）推出了

據說新版效能有所改進，這裡有不錯的網上介紹，我就不再多寫了

官方網站

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.

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”.
