How to remove a Trojan, Virus, Worm, or other Malware

Dialers, Trojans, Viruses, and Worms Oh My!

If you use a computer, read the newspaper, or watch the news, you will know about computer viruses or other malware. These are those malicious programs that once they infect your machine will start causing havoc on your computer. What many people do not know is that there are many different types of infections that are categorized in the general category of Malware.

Malware - Malware is programming or files that are developed for the purpose of doing harm. Thus, malware includes computer viruses, worms, Trojan horses, spyware, hijackers, and certain type of adware.

恶意软件包括电脑病毒,蠕虫,特洛伊木马,间谍软件,劫持,广告软件。(看到这儿想到之前用的那个国外软件是spyhunter,对付ad软件效果碾压国产。

This article will focus on those malware that are considered viruses, trojans, worms, and viruses, though this information can be used to remove the other types of malware as well. We will not go into specific details about any one particular infection, but rather provide a broad overview of how these infections can be removed. For the most part these instructions should allow you to remove a good deal of infections, but there are some that need special steps to be removed and these won‘t be covered under this tutorial.

这篇文章不会深入讨论某种感染的细节,而是提供一个怎样摈除这些感染的概览。

Before we continue it is important to understand the generic malware terms that you will be reading about.

下面介绍的是一些常见的恶意软件形式:

Adware - A program that generates pop-ups on your computer or displays advertisements. It is important to note that not all adware programs are necessarily considered malware. There are many legitimate programs that are given for free that display ads in their programs in order to generate revenue. As long as this information is provided up front then they are generally not considered malware.

广告软件-在电脑上弹出广告,不过并不是所有的都是,因为很多合法软件也会为了收益这样做。

Backdoor - A program that allows a remote user to execute commands and tasks on your computer without your permission. These types of programs are typically used to launch attacks on other computers, distribute copyrighted software or media, or hack other computers.

后门软件-不经允许远程操作用户电脑的软件。

Dialler - A program that typically dials a premium rate number that has per minute charges over and above the typical call charge. These calls are with the intent of gaining access to pornographic material.

拨号机-通话费会比平时贵很多,通常伴随淫秽信息。。

Hijackers - A program that attempts to hijack certain Internet functions like redirecting your start page to the hijacker‘s own start page, redirecting search queries to a undesired search engine, or replace search results from popular search engines with their own information.

劫持-会劫持网络功能,比如把你的主页重导向另外的主页,替换搜索的信息等。

Spyware - A program that monitors your activity or information on your computer and sends that information to a remote computer without your knowledge.

间谍软件-监视你的活动和信息并送往其他地方。

Trojan - A program that has been designed to appear innocent but has been intentionally designed to cause some malicious activity or to provide a backdoor to your system.

特洛伊木马-看上去无害但是会对系统有害或者为之后的远程操作留下后门。

Virus - A program that when run, has the ability to self-replicate by infecting other programs and files on your computer. These programs can have many effects ranging from wiping your hard drive, displaying a joke in a small box, or doing nothing at all except to replicate itself. These types of infections tend to be localized to your computer and not have the ability to spread to another computer on their own. The word virus has incorrectly become a general term that encompasses trojans, worms, and viruses.

病毒-当启动时会不断自我复制感染其他程序和文件的程序,并不能主动传染其他电脑。需要注意的是特洛伊木马,蠕虫并不包含在电脑病毒里。

Worm - A program that when run, has the ability to spread to other computers on its own using either mass-mailing techniques to email addresses found on your computer or by using the Internet to infect a remote computer using known security holes.

蠕虫-可以主动传染其他电脑。


How these infections start

Just like any program, in order for the program to work, it must be started. Malware programs are no different in this respect and must be started in some fashion in order to do what they were designed to do. For the most part these infections run by creating a configuration entry in the Windows Registry in order to make these programs start when your computer starts.

Unfortunately, though, in the Windows operating system there are many different ways to make a program start which can make it difficult for the average computer user to find manually. Luckily for us, though, there are programs that allow us to cut through this confusion and see the various programs that are automatically starting when windows boots. The program we recommend for this, because its free and detailed, is Autoruns from Sysinternals.
好吧解决办法是:Autoruns。重点:免费!
When you run this program it will list all the various programs that start when your computer is booted into Windows. For the most part, the majority of these programs are safe and should be left alone unless you know what you are doing or know you do not need them to run at startup.

At this point, you should download Autoruns and try it out. Just run the Autoruns.exe and look at all the programs that start automatically. Don‘t uncheck or delete anything at this point. Just examine the information to see an overview of the amount of programs that are starting automatically. When you feel comfortable with what you are seeing, move on to the next section.

 

Use an anti-virus and anti-malware program to remove the infections

Make sure you are using an anti-virus program and that the anti-virus program is updated to use the latest definitions. If you do not currently have an anti-virus installed, you can select one from the following list and use it to scan and clean your computer. The list below includes both free and commercial anti-virus programs, but even the commercial ones typically have a trial period in which you can scan and clean your computer before you have to pay for it.

It is also advised that you install and scan your computer with MalwareBytes‘ Anti-Malware and Emsisoft Anti-Malware. Both of these are excellent programs and have a good track record at finding newer infections that the more traditional anti-virus programs miss. Guides on how to install and use these programs can be found below.

How to use Malwarebytes‘ Anti-Malware to scan and remove malware from your computer
How to use Emsisoft Anti-Malware to scan and clean malware from your computer

After performing these instructions if you still are infected, you can use the instructions below to manually remove the infection.

 终于讲到正题了:所以是下载Autoruns,然后安全模式启动,找到 autoruns.exe双击启动。

How to remove these infections manually

We have finally arrived at the section you came here for. You are most likely reading this tutorial because you are infected with some sort of malware and want to remove it. With this knowledge that you are infected, it is also assumed that you examined the programs running on your computer and found one that does not look right. You did further research by checking that program against our Startup Database or by searching in Google and have learned that it is an infection and you now want to remove it.

If you have identified the particular program that is part of the malware, and you want to remove it, please follow these steps.

  1. Download and extract the Autoruns program by Sysinternals to C:\Autoruns
     

  2. Reboot into Safe Mode so that the malware is not started when you are doing these steps. Many malware monitor the keys that allow them to start and if they notice they have been removed, will automatically replace that startup key. For this reason booting into safe mode allows us to get past that defense in most cases.
     

  3. Navigate to the C:\Autoruns folder you created in Step 1 and double-click on autoruns.exe.
     

  4. When the program starts, click on the Options menu and enable the following options by clicking on them. This will place a checkmark next to each of these options.

    1. Include empty locations
       

    2. Verify Code Signatures
       

    3. Hide Signed Microsoft Entries
       

  5. Then press the F5 key on your keyboard to refresh the startups list using these new settings.
     

  6. The program shows information about your startup entries in 8 different tabs. For the most part, the filename you are looking for will be found under the Logon or the Services tabs, but you should check all the other tabs to make sure they are not loading elsewhere as well. Click on each tab and look through the list for the filename that you want to remove. The filename will be found under the Image Path column. There may be more than one entry associated with the same file as it is common for malware to create multiple startup entries. It is important to note that many malware programs disguise themselves by using the same filenames as valid Microsoft files. it is therefore important to know exactly which file, and the folder they are in, that you want to remove. You can check our Startup Database for that information or ask for help in our computer help forums.
     

  7. Once you find the entry that is associated with the malware, you want to delete that entry so it will not start again on the next reboot. To do that right click on the entry and select delete. This startup entry will now be removed from the Registry.
     

  8. Now that we made it so it will not start on boot up, you should delete the file using My Computer or Windows Explorer. If you can not see the file, it may be hidden. To allow you to see hidden files you can follow the steps for your operating system found in this tutorial:

    How to see hidden files in Windows
     

  9. When you are finished removing the malware entries from the Registry and deleting the files, reboot into normal mode as you will now be clean from the infection.

How to protect yourself in the future

In order to protect yourself from this happening again it is important that take proper care and precautions when using your computer. Make sure you have updated antivirus and spyware removal software running, all the latest updates to your operating system, a firewall, and only open attachments or click on pop-ups that you know are safe. These precautions can be a tutorial unto itself, and luckily, we have one created already:

Conclusion

Now that you know how to remove a generic malware from your computer, it should help you stay relatively clean from infection. Unfortunately there are a lot of malware that makes it very difficult to remove and these steps will not help you with those particular infections.
