http://do-search.com/ comes up on start-up despite instructions for blank screen, how can I stop this site from loading?

Never subscribed. Don't want to subscribe. Seems to have shown up with Firefox V 25. Removed it from about:config. Blocked all cookies and graphics. Tools / options is set to start with blank page, yet on start-up it loads every time. Is there anyway to block URLs in FireFox?

Product claims to be from "Smott Technology Limited" but can't find this company in an internet search.

Chosen solution

hello, this sounds like a problem possibly caused by malware on your pc. please go to firefox > addons > extensions & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc). also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and run a full scan of your system with the security software that you have in place and different other tools like the free version of malwarebytes & adwcleaner.

Remove a toolbar that has taken over your Firefox search or home page Troubleshoot Firefox issues caused by malware

hello, this sounds like a problem possibly caused by malware on your pc. please go to firefox > addons > extensions & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc). also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and run a full scan of your system with the security software that you have in place and different other tools like the free version of malwarebytes & adwcleaner.

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.

I used a variety of malware checkers - Microsoft, Norton, Malwarebytes, and adwcleaner. All but adwcleaner said no malware. adwcleaner brought up and dispensed with a bunch of things it said weren't good. But no joy! I disabled all of my add-ons and extensions -- No Joy! I restored my system back four days, but no joy again! Finally I deleted my copy of FireFox and reloaded it and by gosh that worked!!! No more Do-search. Unfortunately, still don't know what caused this, but I'll certainly continue to be careful.

Interestingly, I found I had the same problem in Internet Explorer, but none of the actions above, including removing and reinstalling fixed the problems. But that's really not a problem because I never use Internet Explorer when FireFox is so much better!!!

All, thanks so much for your advice and counsel. I really appreciate the help! V/R Steve

It is very sad  :-< but many of the software down-loaders / installers will trick you into installing not only their program, but other programs as well. You have heard of the fine print in shady contracts, right? Well, some installers you need to look at the teeny tiny fine print. You are thinking you are giving the program permission to instal the program you want by using the recommended option. But if you use the manual option instead, you discover all kinds of stuff that you do not even know what it is or what it does. From now on, everyone needs to use the manual option to put a stop to this.

You can check the target line in the Firefox desktop shortcut to make sure that nothing is appended after the path to the Firefox program.

All the advice about getting Adware software wasted a whole 5 hours of time for me.

I finally decided to run %APPDATA%\Mozilla\Firefox\Profiles from the 'windows start/run' line...

When I got to the store for the profiles I went back two directory entries to the 'Mozilla' folder then searched for "do-search" inside the files.

I found several instances inside a .js file and deleted them.

problem solved!

Not sure why this isn't in the fix instructions.

I did not remove the entries in the sessionstore.js, as that appears to be past history stuff...(don't know but I solved the problem.)
