I have tried removing it from the extensions section in Chrome settings, but it reappears every time I reopen Chrome. My computer runs on Windows 7 Ultimate
As you haven't specified, I assume, you are using Windows OS. It is a potential malware. You have to uninstall the program explicitly from control panel and then restart chrome. It should work. If it doesn't work, then you might have to scan your system by some good anti-virus like kaspersky or avast.
You should download Microsoft Security Essentials (or another similar anti-virus program) I've used MSE in the past and it works well (without noticeably slowing down your system) there are no up-sells with it either (like you'll get w McAfee or Norton antivirus).
Just go to Google, search Microsoft Security Essentials. Then download and install the latest version (for Windows 7 32-bit)
It's free and should get rid of this program (looks like Malware to me).

I need to emulate an older version of chrome. I want to avoid the solution where I have to uninstall the current version and install the desired one each time I need to test my app. I came across this article but it doesn't quite answer my question. Thank you!
It's not possible to emulate older versions of Chrome from within DevTools, as is possible in IE. It's not very reliable to emulate them anyway. I've used IE 8 emulator in the past, and on occasion it has provided different results from the version I installed on an XP VM.
In theory, it should be possible to install multiple Chrome instances side-by-side because the installation directory is OS user based. However, I don't think the installations are fully isolated from one another. At least in Windows, the application would likely write to the same registry keys. In OSX, you might be alright, provided you modify the user directory path.
An alternative solution would be trying the portable versions of Chrome that appear over the Internet, usually illegally. Everything is self contained in a directory, but it will likely perform differently from normal installations. Check out PortableApps.
I think the best solution would be to set up some VMs for the different environments and browsers you want to test with. You can manually set up these, using VirtualBox or similar. Many hosted providers will allow you to spin up fresh VMs with automated tasks to install applications and services. You have to pay for these though.
If you just need to check what server returns for old browsers (not full emulation), you can set User-Agent in Network Conditions (for now, chrome 67).
Just for completeness, here is a link (September 2021) that provides historical snapshots of the 'chromium' browser, sorted per operating system and per 'position'. I needed this when I had to test on an 8-year old version of Chrome(~ium)

Just found out that different versions of Google Chrome can be installed.
You will have to uninstall your existing version.
Download the package from here - https://www.chromium.org/getting-involved/dev-channel
Follow the instructions and install.
Hope this helps someone. The downside is you have to uninstall your current version.
Cheers!
Today you can run Windows Sandbox to avoid installing malicious programs. (Windows Professional or Enterprise Edition is required).

Windows Sandbox Doc
While I don't have a way to emulate a different version, I did find a way to have a current and an old version installed at the same time. For the 'current' version I installed Chrome Beta. Then I set the regular version of Chrome to the older version I needed.
Google's docs didn't put all the information in one place, so here are the steps for a normal Chrome user in Windows 10:
Download the Google Update policy template (alternatively Chrome Enterprise also contains the files you'll need) and unzip it.
Copy the .admx and .adml files into %systemroot%/PolicyDefinitions (.admx files go there and .adml in the language subfolder (en-US) as found in the zip you downloaded)
Open Group Policy editor and the required settings now exist
In Computer Configuration->Administrative Templates->Google->Google Update->Applications->Google Chrome,
set Rollback to target version to enabled
set the Target version prefix override to enabled and your desired version
(e.g. 86. for version 86)
Finally open Chrome, go to Settings->About and let it check for updates. Chrome will automatically download the target version and prompt you to restart.
Do note that this deletes local user profiles and recreates them from remote including redownloading browser extensions, so use with caution. Remember to go back to the normal version of Chrome by unsetting the Group Policy settings and letting Chrome update itself when you're done.
You Need Various Browsers
So, you need to test
your web stuff
with various browsers.
Some of these browsers
may be unavailable
on the OS
in which you develop.
Microsoft browsers (Internet Explorer)
are only available for Windows.
Further,
each Windows installation
can have only a single
Microsoft browser.
Also, Safari is only available in OS X.
The Obvious Solution: Virtualization
The obvious solution is
hardware virtualization.
The idea is to host
virtual machines
in your development system,
in which you'll be free to install
the operating system
and browser combination
that you require for testing.
So, How?
How do I do that?
Safari: Only on OS X
The latest version of
Safari
is available only for
recent versions
of OS X.
running of OS X in virtualization
is supported only on
Apple hardware.
For further details, read:
VirtualBox's documentation on OS X guests
VMware's "Virtualizing Apple Mac OS X (1000131)".
Manually
You can
create VM's
and install
the OS/browser
combinations
that you require.
I recommend VirtualBox.
Advantages of Manual
You do not have to
discard
the changes in the VM
after each use session.
And, unlike with ievms,
you do not have to
reinstall from scratch
every time the license expires.
Apart from saving time,
this means that
you can configure/customize
the operating system and browser
and install additional software
according to your requirements and preferences.
The Disadvantage
Valid licenses for the
software involved
may be required by law.
Tips
The same version of browser
may behave differently
on different versions of Windows.
Provide enough memory to your VM's.
I recommend at least 1GB, per VM.
To be sure,
check how much memory is free
during a typical testing session.
If you wish to test on
multiple versions
of Internet Explorer,
see you install from
Windows installation media
that includes the version of Internet Explorer
that you require
and not a newer one.
Virtualization software
(like VirtualBox)
have powerful snapshot features.
Take snapshots after you make configuration
changes or install software or updates.
In case something goes bad,
you would be able to easily revert.
Clone the VM instead of
installing the same version of Windows
on multiple VM's.
After you install Windows on one VM,
clone it into a linked clone
(this is VirtualBox terminology)
and then simply upgrade Internet Explorer.
Choose to reinitialize the MAC addresses when you clone
(VirtualBox asks about this).
Make sure that the
browser will remain the same version
by turning off automatic updates
or choosing to ignore
the specific browser updates.
Disable System Restore.
Disable the screensaver.
Install the VirtualBox Guest Additions
and upgrade them each time you upgrade VirtualBox.
Configure your web browser
(home page, new tab page,
automatic form filling,
disable "accelerators", etc.).
ievms
An easy and popular way
for developers to
get some VM's with
Microsoft browsers
up and running
is ievms.
Time and Storage Saving Tip Regarding ievms
To save time and storage,
intall only those browsers that you intend to use.
I have observed inconsistent behavior using the Web Developer extension (Chris Pederick) in Google Chrome on these different machines:
My PC running Windows 7 Home Premium 64-bit
A VirturalBox Virtual Machine (VM) running Ubuntu 12 on my PC
A VM running a updated, fresh install of Windows 7 Home Premium 64-bit on my PC
I have the same version of Google Chrome and Web Developer installed on all these machines. However, for some reason, Web Developer does not work as expected on my PC. It works perfectly on the Ubuntu VM and the Windows VM.
On my PC, about 95% of the time the Custom Tools functions (Validate CSS, Validate HTML, etc.) in Web Developer do nothing when clicked (they should open new tabs to the W3C validators).
I have uninstalled and reinstalled Google Chrome on my PC several times. I have even manually gone through the file system and registry to completely remove all traces of Google Chrome before reinstalling. Nothing I've attempted so far has corrected this problem.
Of course, due to Google's 'field trials', all these machines have slightly different variations (as reported by chrome://version), but I would doubt that is the source of the problem.
Any ideas or suggestions?
OK, here's a possible clue...
It has baffled me why this problem NEVER occurs in my virtual machine (VM); only on the host. Same version of OS, Chrome, and Web Developer installed on both. May have discovered why.
My standard settings for VMs is to use only one CPU. As a test, I changed the VM to use two CPUs. BOOM! I can reproduce the problem on my VM. Change back to one CPU - can not reproduce the problem.
Does this suggest a problem with threading in Chrome?
I am using custom sync options to synchronize only some of the artifacts from a Google chrome installation - just Bookmarks, Extensions and Open Tabs. All three are working on well on my two windows computers - but on the Linux machine, I am not getting the extensions. I have tried wiping the Linux Chrome data (by removing ~/.config/google-chrome/ and re-configuring it, the the problem remains the same.
I am wondering if there are any logs that the chrome browser produces that can give me a hint on what the problem might be.
Thanks a lot
Looks like this is not a bug but a "feature", different support of extension per OS, but seems there might be hope this is fixed in future releases see:
Chrome Web Store to get multi-platform app support for Windows, Mac, Linux, Android, iOS, and Chrome OS

I'm currently designing a website on a Mac. The design works fine in Chrome, Safari and Firefox. Now I'm about to test it with different versions of Internet Explorer. The problem is that I don't have access to a Windows machine at the moment. What's the best way to test a webdesign for IE on a Mac?
I use BrowserStack.com, which is pretty cool. But the debugging tool (Firebug) gets really slow on IE7 and IE8.
So here it is a way to have IE7, 8 and 9 working in your mac:
1) Download & Install VirtualBox
2) Launch the Terminal (located in /Applications/Utilities/)
3) Decide which versions of Internet Explorer you want to download and install – each version of Internet Explorer is contained within a separate virtual machine that runs within VirtualBox. In other words, if you want to run Internet Explorer 7, 8, and 9, you will need to download three separate VM’s, which may take a while so keep that in mind. Select the text below and copy it:
3.1) Install ALL versions of Internet Explorer: IE7, IE 8, and IE 9
curl -s https://raw.githubusercontent.com/xdissent/ievms/master/ievms.sh | bash
3.2)Install Internet Explorer 7 Only
curl -s https://raw.githubusercontent.com/xdissent/ievms/master/ievms.sh | IEVMS_VERSIONS="7" bash
3.3) Install Internet Explorer 8 Only
curl -s https://raw.githubusercontent.com/xdissent/ievms/master/ievms.sh | IEVMS_VERSIONS="8" bash
3.4)Install Internet Explorer 9 Only
curl -s https://raw.githubusercontent.com/xdissent/ievms/master/ievms.sh | IEVMS_VERSIONS="9" bash
Copy and paste the selected command from above into the Terminal and hit return, this will start the download and conversion process. How long this takes depends on your internet connection and how many versions of Internet Explorer you chose to install
Launch VirtualBox and boot Windows & Internet Explorer – select the virtual machine corresponding to the version of Internet Explorer you intend to use: IE7, IE8, IE9, then click on the “Start” button to boot that Windows machine with that version of Internet Explorer.
Remember that the default Windows admin password is “Password1″, it’s also the password hint within the VM should you forget it.
That’s really all there is to it. These commands are part of the ievsms script from xdissent and it manages the entire download, conversion, and installation procedure, it doesn’t get much easier.
VM Snapshots Circumvent Microsofts 30 Day Limitation
The other great thing about this method is that it circumvents Microsofts 30 day limitation by utilizing snapshots, a feature built into VirtualBox. This preserves the original Windows VM state and allows you to continuously use the IE virtual machine without any time limitation simply by reverting to the original snapshot once the 30 day lock occurs.
To use a snapshot after the 30 day Windows expiration, just open VirtualBox, select the IE VM, and click on the “Snapshots” button. From here you can boot from the original snapshot that was created and use IE again for another 30 days. You can do this indefinitely, effectively having a clean IE test environment forever.

You can use a virtual machine, such as VMWare (http://www.vmware.com/). Or you can use Wine (http://www.winehq.org/).
Both systems also allow you to then test IE7 and lower, possibly using IETester. I find IETester to be excellent.
I've used them both and they worked for my needs.
Crossover sounds interesting.
To get completely deluxe, you can download Firebug Lite (http://getfirebug.com/firebuglite), which lets you inspect the DOM kind of like Firebug. It's not quite as nice, but a good augmenter for Developer Tools in IE.
You could use Adobe BrowserLab.
Your options are basically, in order of quality:
Run Windows under virtualization.
Run browsers remotely using a tool like browsershots.org.
Ask a friend running Windows to look at the site for you.
Run Explorer via WINE / Crossover Desktop.
Install Crossover, which will allow you to run IE on your Mac without the overhead of a full VM.
http://www.codeweavers.com/compatibility/browse/name/?app_id=4225
I would try out the trial first, because IE8 is listed as "Bronze" compatibility level which is not the greatest.
If running under Wine, you will want to install each version of IE into its own prefix without other programs, and insure that various pre-requisites are available. Google for details.
It works reasonably well then, though new wine updates often can cause it to crash-- alas.
Oracle VirtualBox works very well. Working with it is pretty basic, and best of all it's free:
Download Oracle VirtualBox
Install Internet Explorer
Open Oracle VirtualBox
Done!
For detailed instructions reference this Internet Explorer mac testing guide. There's no point in reposting everything here it's kind of detailed.
Update October 2012:
I just found browserling.com which seems to be quite convenient. Basic test are free, for more intensive once there's a subscription.
I used to test with Parallels, but I've grown tired of updating Windows versions (not to mention buying Windoes just for IE is ridiculous) and keeping up with IE version clashes etc. so a subscription based service seems to be a more convenient solution.
I know this is old but for anyone who does this regularly enough a service like litmus.com is also an option. Of course having an actual install in some sort of virtual machine is the way to go if you're needing it a lot.
The best way to run ie7 - ie10 on a mac that I found is to run oracle virtual machine and install all versions of the browswer. This route is completely free and runs outside the browser like some of these other options.
The only downside to this method is it takes up a lot of space.
