Only 4 Free 只为免费

随着电脑软件技术和网络技术越来越发达，计算机病毒也越来越猖獗。不久前，大家都知道的熊猫烧香病毒给很多网民带来了不可挽回的损失。Viruses（病毒）、spyware（间谍软件）、scareware（欺骗软件）、trojans（木马）、和 worm（蠕虫）、恶意广告软件（adware） 这些名词你能分的清吗？这篇文章将为你一一解释，使你对这些名词有个深刻的了解，通过学习你可以教你的朋友和家人！、 什么是恶意软件（malware）？ Malware恶意软件是malicious 和software两个词的合成词。它是Viruses（病毒）、spyware（间谍软件）、scareware（欺骗软件）、trojans（木马）、和 worm（蠕虫）、恶意广告软件（adware） 等的统称，它是被人为的设计来破坏你的计算机和盗取你的信息的恶意软件。

[b]病毒（VIRUSES）掀起一场文件吞噬的灾难[/b]

计算机病毒是一个程序，一段可执行码 ,对计算机的正常使用进行破坏，使得电脑无法正常使用甚至整个操作系统或者电脑硬盘损坏。就像生物病毒一样，计算机病毒有独特的复制能力。计算机病毒可以很快地蔓延，又常常难以根除。它们能把自身附着在各种类型的文件上。当文件被复制或从一个用户传送到另一个用户时，它们就随同文件一起蔓延开来。这种程序不是独立存在的，它隐蔽在其他可执行的程序之中，既有破坏性，又有传染性和潜伏性。轻则影响机器运行速度，使机器不能正常运行；重则使机器处于瘫痪，会给用户带来不可估量的损失。通常就把这种具有破坏作用的程序称为计算机病毒。 除复制能力外，某些计算机病毒还有其它一些共同特性：一个被污染的程序能够传送病毒载体。当你看到病毒载体似乎仅仅表现在文字和图像上时，它们可能也已毁坏了文件、再格式化了你的硬盘驱动或引发了其它类型的灾害。若是病毒并不寄生于一个污染程序，它仍然能通过占据存贮空间给你带来麻烦，并降低你的计算机的全部性能。

[b]间谍软件（spyware）盗取你的信息[/b]

双重特性软件是对Spyware 的最好描述。它驻留在计算机的硬盘中，通常具备实用的、具吸引力的基本功能。这一核心功能与间谍作用无关。它通常以免费软件的形式提供，有可能是一个实用 程序、MP3 播放器或某种游戏。问题在于，除了主要功能外，Spyware还具有一个次要的、较为隐秘的组件。它收集有关用户操作习惯的信息并将这些信息通过互联网发 送给软件的发布者。由于这一过程是在您不知情的情况下进行，因此具有此类双重功能的软件通常被称作Spyware(间谍软件)。

[b]欺骗软件（Scareware）胁持电脑勒索赎金[/b]

Scareware是欺骗软件。它也被称为“无赖扫描仪”软件或“fraudware”，其目的是为了吓唬购买和安装的人。 就像任何木马软件，scareware蒙骗世人双击安装产品和用户不知情。在scareware的情况下，诈骗手法是，以显示您的计算机受到攻击可怕的画 面，然后scareware将自称是反病毒解决方案对这些袭击。 Scareware和流氓扫描仪已成为数百万美元的诈骗业务，成千上万的用户在该网上诈骗每月下降。人们的恐惧和缺乏技术知识捕 食，scareware产品将诈骗为19.95美元一个人，刚刚展示了病毒攻击假屏幕。

[b]特洛伊木马（Trojans）安装后门[/b]

木马（Trojan）这个名字来源于古希腊传说(荷马史诗中木马计的故事,Trojan一词的本意是特洛伊的,即代指特洛伊木马,也就是木马计的故事)。 “木 马”程序是目前比较流行的病毒文件，与一般的病毒不同，它不会自我繁殖，也并不“刻意”地去感染其他文件，它通过将自身伪装吸引用户下载执行，向施种木马 者提供打开被种者电脑的门户，使施种者可以任意毁坏、窃取被种者的文件，甚至远程操控被种者的电脑。“木马”与计算机网络中常常要用到的远程控制软件有些 相似，但由于远程控制软件是“善意”的控制，因此通常不具有隐蔽性；“木马”则完全相反，木马要达到的是“偷窃”性的远程控制，如果没有很强的隐蔽性的 话，那就是“毫无价值”的。 它是指通过一段特定的程序（木马程序）来控制另一台计算机。木马通常有两个可执行程序：一个是客户端，即控制端，另一个是服务端，即被控制端。植入被种者 电脑的是“服务器”部分，而所谓的“黑客”正是利用“控制器”进入运行了“服务器”的电脑。运行了木马程序的“服务器”以后，被种者的电脑就会有一个或几 个端口被打开，使黑客可以利用这些打开的端口进入电脑系统，安全和个人隐私也就全无保障了！ 木马的设计者为了防止木马被发现，而采用多种手段隐藏木马。木马的服务一旦运行并被控制端连接，其控制端将享有服务端的大部分操作权限，例如给计算机增加 口令，浏览、移动、复制、删除文件，修改注册表，更改计算机配置等。 随着病毒编写技术的发展，木马程序对用户的威胁越来越大，尤其是一些木马程序采用了极其狡猾的手段来隐蔽自己，使普通用户很难在中毒后发觉。

[b]蠕虫病毒（Worms）通过网络感染[/b]

蠕虫病毒是一种常见的计算机病毒。它的传染机理是利用网络进行复制和传播，传染途径是通过网络、电子邮件以及U盘、移动硬盘等移动存储设备。比如2006年以来危害及大的“熊猫烧香”病毒就是蠕虫病毒的一种。蠕虫程序主要利用系统漏洞进行传播。它通过网络、电子邮件和其它的传播方式，象生物蠕虫一样从一台计算机传染到另一台计算机。因为蠕虫使用多种方式进行传播，所以蠕虫程序的传播速度是非常大的。 蠕虫侵入一台计算机后，首先获取其他计算机的IP地址，然后将自身副本发送给这些计算机.蠕虫病毒也使用存储在染毒计算机上的邮件客户端地址簿里的地址来传播程序。虽然有的蠕虫程序也在被感染的计算机中生成文件，但一般情况下，蠕虫程序只占用内存资源而不占用其它资源。蠕虫还会蚕食并破坏系统，最终使整个系统瘫痪。

[b]恶意广告软件（adware）-让你不知不觉装上它[/b]

广告软件（Adware）是指 未经用户允许，下载并安装或与其他软件捆绑通过弹出式广告或以其他形式进行商业广告宣传的程序。安装广告软件之后，往往造成系统运行缓慢或系统异常。危害：此类软件往往会强制安装并无法卸载；在后台收集用户信息牟利，危及用户隐私；频繁弹出广告，消耗系统资源，使其运行变慢等。例如：用户安装了某下载软件后，会一直弹出带有广告内容的窗口，干扰正常使用。还有一些软件安装后，会在IE浏览器的工具栏位置添加与其功能不相干的广告图标，普通用户很难清除。防治广告软件，应注意以下方面 ：第一，不要轻易安装共享软件或"免费软件"，这些软件里往往含有广告程序、间谍软件等不良软件，可能带来安全风险。 第二，有些广告软件通过恶意网站安装，所以，不要浏览不良网站。第三，采用安全性比较好的网络浏览器，并注意弥补系统漏洞。

Comodo Time Machine is a free program that can roll your system back in time, on-demand, to a previous state. It provides the ability to “undo” any kind of undesirable event, such as a virus or malware infestation or any event or events that might have caused your PC to become too cluttered, slow, or unresponsive, by giving you the ability to revert back to a baseline state or to a snapshot of the system taken before the problem started. It also provides the ability to recover any data or files that may have been accidentally deleted, saved-over, or damaged in any way.

Comodo Time Machine is unlike Windows restore in that it doesn’t just affect the registry and system settings, but transforms your entire system including your files and everything on your hard drive. What is interesting is that if you do revert back to an earlier state, the software will still preserves the “future” point which you reverted from, allowing you to reclaim any files that had been changed or added if you need to. Comodo Time Machine takes regular scheduled automatic snapshots, making it possible to use the protection it provides while on auto pilot, so to speak, without having to be managing it manually it at all times.

[Update 3/24/2010: after publishing this review and reading some of the user comments I recommend that you NOT install this program without taking an image of your hard drive first. Some good imaging freeware are Paragon Backup & Recovery, DriveImage XML, and Easeus Todo Backup. ] If you do not know what a disk image is then definitely stay away from this program.

Imagine being able to restore yesterday’s version of a file that you had just accidentally saved over or permanently deleted; Imagine being able to install and test all sorts of software whilst having the option to revert back to a previous stater; Imagine being able to easily get rid of the nastiest virus or malware infestations, even those that would normally prevent you from booting the system back again. Comodo Time Machine makes all of this possible, but it does so at the potential cost of gobbling up a significant chunk of hard disk space.

To be clear, I find this program to be very compelling and extremely interesting, but would stop short from recommending it for every user. Comodo Time Machine can only do what it does given enough hard drive space that it can store and preserve all the different versions of files that change on your hard drive, including any large files that you might delete or move after use, such as videos or other media files. Everything will be preserved, at least across different snapshots. Which makes it more suited to some situations than others.

Here’s a list of scenarios where Comodo Time Machine might be an excellent fit.

•Users who have large amounts of unused hard drive space. Comodo Time Machine recommends 10 gigs of free space and 4 gigs at minimum; however, if you download a lot of large media files on your computer you may need multiples of that.

•Public computers: such as those in libraries, internet cafes, etc.

•Software developers and testers: will find this to be extremely convenient; they can rollback deployed software without uninstalling. Software reviewers like myself would also find it extremely useful.

•Computers used by novice users: i.e. you can put it on grandma’s computer or the computer used by the kids, etc, and know that you can restore files they accidentally delete or rollback any dubious software or malware that they accidentally install.

Cases where Comodo Time machine is not a good fit:

•If your PC is stretched for hard drive space: Comodo recommends that you have 10 gigs available, and I would strongly discourage you from installing if you have less. Moreover, do not install if you have these spare gigs but might conceivably fill them up at a later point after installation.

•If you download a lot of large files on a regular basis: because of its promise to roll back your system to any saved snapshot, these large files will in fact be saved into the snapshots and remain on your hard drive even after you move or delete them. On my system, because I download large media files (read: torrent movies) it took only 3 snapshots to fill the 10 gigs that this program had allocated for itself. Once I got to that point I could no longer do anything whatsoever on my PC until I had either (a) removed some snapshots and rebooted, or (b) reset my base snapshot to the current snapshot and rebooted. Both of these methods can end up freeing up gigabytes for Comodo Time Machine to work with.

With the above in mind, here is a list of PROs and CONs that can shed light on why this is a brilliant program but also why you should be careful if you want to install it:

What I like about this program:

•It can restore previous versions of files: i.e. files that have been accidentally deleted or even saved over. How cool is that?

•Snapshots are taken in manner of seconds: quite unlike, for example, a re-imaging of your hard drive, which can be involved and time consuming even when the images are put together incrementally. Re-setting the “baseline” snapshot to the current snapshot will require a reboot, though, and will take about 10 minutes or so.

•Very small memory footprint: the Comodo Time Machine process and its system tray process combined take up less than 7 megs of memory.

•Snapshot scheduling: you can schedule snapshots e.g. hourly, daily, weekly, monthly, or a one time event. You can also set it to take a snapshot on every system start (and even limit that to once a day if you like). This enables you to set scheduling one time and then essentially forget about the program, knowing you are protected.

•Synchronizing files or folders: across snapshots, can be done via the right click context menu (simply right click on a file or folder and click “synchronize”) or via a search box in the program interface. You can overwrite the current files with files from stored snapshots or keep both versions.

•You can set a rule for synchronizing files and folders: in other words, tell the program to always maintain the “new” versions of these files or folders even when moving back to a stored snapshot.

•The boot up console: allows you to perform all sorts of operations, such as booting into different snapshots, while booting. It also means that you will always be able to boot into your system.

What I do NOT like about this program: some of these are “wish list” items, although I realize some points are necessary for the program to deliver what it promises.

•Discrepancy between what Windows shows the free hard drive space to be, and the Comodo Time Machine free space: at one point Windows told me that I had 12 gigs free, while Comodo Time Machine had 0 space left and my system ground to a halt. This happened after I deleted a whole bunch of media files that were still preserved in the snapshot, and it was impossible to do anything except either delete snapshots or reset the baseline (and then reboot in either case). And although I could understand why this had come to be the case, it made me reconsider giving a blanket recommendation of this program to users who may not be tech savvy.

•No way to compare and edit changes across snapshots: I would have loved at least to be able to see which files changed. Also, the option to permanently “let go” and delete some of these manually. The ability to filter out system files in such a comparison would be great as well. What I have found, in terms of file synchronization, is that it is typically impossible to remember all the files that have changed during the course of a couple of days of normal computer use, let alone a couple of weeks, making the synchronization function somewhat of a hit or miss affair.

•Multiple boot systems: once you use this on your PC you cannot have a situation where you boot into multiple OS’s on that machine, unless you can install the program on all the different OS’s that you use on that particular machine (which limits you to Windows). If you boot into your machine via a USB or Live CD you are cautioned against writing anything to any partition.

•The uninstaller is awful: on my Windows 7 64 bit, I got an error message mid-way through uninstalling that gave me quite a fright. There was no text, just an image of an exclamation point inside an inverse yellow triangle and an “OK” button. It left me wondering whether something had gone wrong and whether I will be able to boot back into my system at all (and kicking myself for not have a created an image of my hard drive before testing this app). It turned out that the blank error message should have read something like “you now need to reboot to continue uninstalling” and it went fine.

•Excluding folders (or wish list item #1): I really wish I could exclude a folder or folders from being included in the snapshots. This way I could designate a folder for transient, gigantic media files that I do not care to have permanently fused into the snapshots. But I do think the likelihood of the developers allowing such a security loophole is probably zero.

•Unclear on why or when some snapshots are performed: despite not having scheduled any snapshots in the scheduler or the settings, the system periodically made these on its own. While such snapshots are typically very useful I would have liked more clarity on when and why these took place.

The verdict: this program provides excellent security and is fairly easy to use; however, it may be suitable for some situations but not others, as outlined above. The bottom line is that if you have a good chunk of hard disk space that you do not typically use Comodo Time Machine may work really well for you.

What is impressive about this software is that it is able to do what it does seamlessly in the background and largely without user intervention. This is not the case when it runs out of hard drive space (you are forced to intervene then), but is true in general.

I like the ambition and scope of Comodo Time Machine. As a software tester I install all sorts of crap on my PC that I typically test and live with for a few days, and the possibility of an instant “undo” function that Comodo Time Machine promises sounds really good. Alas, it may be the case that my 12 free gigs on my hard drive are not enough (esp with my downloading large media files). That said, I am now considering upgrading my hard drive capacity, if only to take advantage of this excellent program.

Before you install this though, make sure you have a backup image of your hard drive (see the top of this posting, in red font, for some good freeware disk imaging options). If you are unclear on what a disk image is then stay away from this program.
