Hi. I am new to AMT and have only been doing HITs for about a week now. While I like a lot of things about it, the first thing that jumped out at me is how much of a security train wreck turking is. Links are not screened and workers are continuously following links that may or may not lead them to malicious sites. On top of that, a lot of tasks require additional software even though it is against the site's ToS. I'm not here to lecture anyone about what they should or shouldn't do though. I just thought I could provide some helpful tips to make tasks safer regardless of whether or not you are already careful. I have some experience with it, and I've been leeching off of the good HITs thread, so I figured its only fair. First off, everyone should understand that you don't have to download something intentionally in order to end up with malware on your computer. You can be exposed to bad things simply by following links, and there are really very few ways to avoid that without losing so much functionality of your browser that you wouldn't be able to do your tasks anyway. One way you can prevent malware is to use a more secure operating system than Windows. Both Mac and Linux OS are much more secure out of the box than Windows, and there is of course much much less malware that targets those OS in the first place. The down side to this route is that a lot of the various 3rd party helper scripts and software might no longer be available to you, and you also wouldn't be able to do anything that involved testing with software that is designed to be used in Windows. If that's not a big deal to you, then this is definitely the way to go in my opinion. Linux is free open source software that you can just download at any time. There are many different versions though. If you have no experience with it and have a system that's at least somewhat up with the times, I would go with Ubuntu. Its not my favorite, but its extremely easy to set up and fairly user friendly for someone that's new to it. You don't have to make a disk or anything. They have a windows installer that you can use to install Ubuntu right inside of windows and then just choose which you want to use when you boot up. You can get that here http://www.ubuntu.com/download/desktop/windows-installer If you're running on a very old junky computer, there are lots of minimal lightweight distros of linux that would be better. Out of those I would recommend Lubuntu. It works very well on computers with low resources and is pretty user friendly too. You'll have to actually make a disk and install on boot though. If you choose to use Windows to do your tasks, the best way to protect yourself from malware is by isolation. There's no way to completely prevent exposure, but you can quarantine and purge to protect your system. Two pieces of software that are free and effective at this are Sandboxie and Virtualbox. Sandboxie is a fantastic program that allows you to run any program inside of a quarantined area (the sandbox) and allow no interaction of that program with anything outside of the sandbox. So, if you run your browser inside of a sandbox and you are exposed to something malicious, your system still won't be affected, because anything that malicious process tries to do is just inside of a virtualization and not your real system. You have to specifically give something permission to come out. You can also set the sandbox to empty every time you use it, and even any changes that may have been caused to your browser itself will vanish. Chrome and IE both use some sort of watered down version of sand boxing that is more practical for everyday use, but nowhere near as secure as this. Also, as far as I know, Firefox has no sand boxing whatsoever. You can download Sandboxie here http://www.sandboxie.com/ (I would use the sandboxie mirror to avoid spam) and it is free to use. After 30 days there is a 5 second delay when you start a program with the free version, but its still very usable like that. There are a lot of different options you can mess with once you get used to it, but in the beginning all you really need to do is just make sure that you run your browser sandboxed when you're doing tasks or other risky things. You can also run any program you download inside of a sandbox or put addons on your sandboxed browser that will vanish when you're done with it. Virtualbox is a program that lets you install and run an entire virtual operating system inside of Windows (or Linux or Mac). By using this method you can create a devoted OS that you use only for tasks and that is completely isolated from the rest of your system. Virtualbox also has a built in feature that lets you take snapshots and save the machine state at any time, so you can even purge any malware that you may get inside of your virtual OS by reverting to the previous state. Virtualbox is free software from Sun/Oracle that you can download here https://www.virtualbox.org/ It would take a long time to do a full tutorlial, but basically the way it works is that you create a virtual hard drive and then install an operating system to it just like you would normally, except that its inside of the system you're using now. If you want Windows, then you just use your Windows disk, make a new Virtualbox, run the new box, and install Windows on it. You can make the drive as large as you want. Just pick dynamic allocation and it will expand and only take up as much room as you use. You might have to read up a little bit if you've never used it before, but really its pretty self explanatory once you get going, so I think it fine to just jump in and just Google if you hit a snag. Once you have it set up its easy as pie. Anyways, if you use one or more of these tools your computer will be much much more secure then if you just rely on some crappy antivirus and call it good. Your system is really exposed to a lot of potential danger, and at the same time you are using a real money account with sensitive information in it. Its worth the time investment to take simple steps to minimize your risk. Sorry if this has already been done before. I hope that its helpful.
