Why did an upgrade of firefox ask to install the malware Bettersurf Extension
On my last upgrade in Firefox (version 25.0), the next time I opened Firefox, I was asked to install the extension Buttersurf.. I have done some reading about this and it is a maleware. Why are you allowing this extension??? I deleted all signs of it from my computer.

hello, firefox downloads directly from mozilla.org are free of any sort of malware. in addition updates are handled automatically by firefox so you don't have to download anything (you can initiate a check for updates in firefox > help > about firefox).
it may have been a fake popup trying to trick you into installing malicious software - so you might also want to run a full scan of your system with the security software already in place and different tools like the free version of malwarebytes, adwcleaner & kaspersky security scan in order to make sure that there isn't already some sort of malware active on your system that triggers these false alerts.
I will run my Kaspersky virus scan and see what happens. I thought it odd that this would happen right after I updated Firefox. I have done no other updates nor installations since.
Your resident AV [Kaspersky] is one of the top performing antiviruses, so should be able to clean most malware from a computer. Malwarebytes Anti-malware has a good reputation for cleaning up malware "infections", and is well worth having as a second opinion back-up. So too is SurfRight's Hitman Pro. That will give you 30 days to find malware, after that it will be necessary to buy a license to get clean-up support.
I do not know adwcleaner, but it appears to be well regarded at Wilders Security Forums.
You might like to consider a "portable" "installation" of Firefox as a means of exploring functionality which is not native to Firefox, but can be added to Firefox by means of one or two extensions which you might not want to install in your main installation, even after you have put them through their paces. Using these add-ons will allow you to explore the issue which perhaps explains your "Buttersurf" infection.
Unfortunately, some time fairly recently, last year perhaps, someone decided to put the popular browsers through a test to determine how they coped with blocking a set of known malware websites. Unfortunately, Firefox scored about 20% in that test, but that would be the "vanilla" edition from Mozilla. However, Firefox can do better, if enhanced with the right add-ons. If it suits you to explore the utility of a 'shadow' installation, you will be able to examine this phenomenon.

If you see it again, could you capture a screen shot of it?
Firefox may display the new add-on warning if, after a restart, it discovered an unexpected new extension in one of its folders. Typically this would have been installed from outside of Firefox. Removing unwanted software through the control panel might have stranded the extension there, but this is speculation on my part.
Jscher2000, I will do a screen if/when it happens again.. maybe after the next update of firefox. I have removed all traces of this program from my computer and am still running my virus program.. it found 2 malewares so far.
This was installed on mine after I got a pop-up recommending install of a firefox update
There was no dialog asking if I wanted this malware
There is no 'remove' button as the mozilla instructions would tell you to use
It installed a folder named 'BetterSurf' in the program files folder
Delete that folder and restart firefox
That is exactly what happened with me yet Firefox is not taking responsibility for it being part of the upgrade. Maybe they need to check out the upgrade to make sure it is not infected with this maleware.
I did delete everything. Firefox is now asking me to update again. Be interesting to know if it happens again.
Hi moxieweb and terry5732, I recommend closing any pop-ups enticing you to update Firefox and instead using
Help > About Firefox > Check for Updates
Unfortunately, some websites and some add-ons promote updates bundled with undisclosed software such as an updater, and perhaps worse.
If you cannot find a Remove button for an extension on the Add-ons page, you should first check the Windows Control Panel, Programs and Features (or Add/Remove Programs) for a way to uninstall it. If that isn't available, it can be manually deleted, or often cleaned out with malware removal tools (some recommended ones in the support article: Troubleshoot Firefox issues caused by malware).
moxieweb, again the Firefox from mozilla.org nor the updates in Firefox does NOT come with BetterSurf.
Mozilla would lose far far too much for what tiny gain they could get by including malware. No version has done so in past over eleven years of this browser's life and Mozilla is not about to start now.
Lately people have been finding crap and malware installed in Firefox after say installing something they download from say Cnet that Cnet bundled the installer with their own adware and whatnot.
How about this for proof as they recently added this malware to blocklist.
BetterSurf (malware) has been blocked for your protection.

James, just wanted to let you know that I did not install anything on my computer from Cnet or anywhere else that would put a maleware on my machine.. the only update I did was Firefox. My main goal here was to warn Firefox that this happened.
This has been an interesting conversation. I'm going to click 'solved this problem. I will continue to use Firefox as it is my preferred browser and hopefully it will not happen again on the next update.
Modified by moxieweb
Well it will not happen as Mozilla never did add Bettersurf or another malware in Firefox setup or update for any version for any OS from mozilla.org
If it were true then there would have been a lot more threads and discussion about it also.
Modified by James
In addition to being blocked, it seemed to install silently, likely what happened to you.
- "This add-on appears to be malware and is installed silently in violation of the Add-on Guidelines."
From the same blocklist James posted in one of his earlier posts.
BetterSurf secretly downloaded itself onto my computer last night. There was no warning - I only became aware of its presence when the screen began to distort, and links began to appear at random on the screen.
This has gotten me very concerned, as I am using the latest version of FF and the security settings were set to warn me about sites trying to install add-ons or extensions, but it seems to have completely evaded them. I hadn't even been near any suspicious sites (I had been on Ebay, Amazon, etc.). Nor have I downloaded anything recently. From what I have seen on the internet, the BS nuisanceware is very recent (it seems to have manifested just over a week ago) and has been affecting FF, IE and Google Chrome browsers.
I managed to delete the BS folder that had been created in the programs (x86) folder, and so far there has been no further sign of it. But I am worried that it might have left something nasty behind, such as info stealing software. I have done a full scan using Norton, and even used the Power Eraser option but nothing suspicious has been detected.
Nevertheless I am anxious that further undetected malware might be residing in the system. I know that it might be a bit too early to ask, but has anyone had any further problems after getting rid of BS? At present I am extremely reluctant to log on into my Ebay, PayPal and Amazon accounts.
Just a bit of further info - it was listed as BetterSurf 1.1 in the extensions list, with email@example.com as its ID
Hi hiding-behind-the-sofa, was there any entry in the Control Panel > Uninstall a Program? Sorting that dialog by date can indicate what else might have been installed around the same time that could be related. Also, you might check your browser download history (in Firefox, Ctrl+j) for that time to see whether that provides any indication of the origin.
Thank you for replying to my post. There were entries in the download history (there was an unidentified installer present) and x86 files but in a haste to get rid of them I didn't see at exactly what time they were downloaded. I could've used them to try and work out from which website the malware came from (it looks likely that this was the result of a drive-by download).
hello, just fyi - we now got the better surf 1.1 addon blacklisted too, so it will be deactivated in all firefox instances: https://addons.mozilla.org/en-US/firefox/blocked/i493
BetterSurf 1.1 has just managed to download itself again this morning!! I thought it was supposed to be blacklisted?
If anyone else is reading this, I was on YouTube when this happened, and I have heard others mention that YT is something of a blackspot when it comes to catching BS.
Sorry, as much as I love FF, I seriously need to think about switching to another browser
