Comments on Delta Search virus

delta search is a real virus
I tried all the options recommended but nothing worked :(. Then I went to cnet download and searched for anit-virus software and found avast! Free antvirus software. The first thing it did was scan my computer and found threats, then allowed me to get rid of them. Then it said there was an issue with my browser and asked if it could clean browsers - and I selected yes and it did.

It removed about 4 items, one that appeared to be HP app (I have HP computer) and a few others that I didnt know what they were. When the removal process was complete, it allowed me to reset my browser to their default setting which I allowed.

I am back to Google with no Delta-Search redirects :).
i tried several options to remove delta , none of the above had any effect whatsoever except to waste my time , i did a system restore , not from last system restore but from an earlier restore point , this seems to have worked and i no longer get any bother from the SCUM that is detla toolbar .
My computer The Delta Search Toolbar Program uses over 19 GB of space when I was uninstalling it
Michael Grihel
wow...i know i had problems with my browser but 401 threats is a little much
Nigel Morris
Delta search can such my left testicle. This page is absolutely NO help whatsoever. Ive followed the instructions and still have the gormless pest that is delta search encrusted on my fucking computer. What an absolute joke.
John Belanger
You clowns are full of crap! I tried to follow YOUR instructions for Firefox but what you said didnt exist. You cown are as much of a virus as the delta search.
thanks for the information, I found this post really usefull.
thank you
John Ng
I recently experienced exactly the problem. My PC runs VISTA X64 Ultimate. One day I noticed Firefox and Google Chrome will no longer Restart from the previous shutdown. Searching around I was informed by Blogs such as this that I was attacked by Browser High-jacking Malware and noticed some unwelcome search toolbars were introduced around 17/04/13. One very bad sysmptom was it took over an hour to complete the normal Startup.
I followed the instructions to remove Delta Search and Babylon toolbar.
My experience was using Control Panel to remove Delta Search, I was left with the Condition that Windows Explorer will crash and restart again whenever I access a drive or a folder render it unusable unless reboot to Safe Mode or start the Command Prompt alias CMD.

I was lucky to boot to Safe Mode and used the VISTA Recovery Procedure to recover to a System prior to the Delta Search Removal.

My experience was Babylon toolbar was the real Highjacker, just guessing, it probably highjacked Delta Search as well. It is very safe to use Control Panel to uninstall Babylon toolbar BUT NOT DELTA SEARCH.

Just uninstalling Babylon Toolbar will be enough to stop the Redirecting of URL whenever Firefox or Chrome being re-started.
However, go direct to, in my case, C://Program(x64)/Delta Seach/ ... , eventually get to "Uninstall", the Delta Searchs own Uninstall Application and run it, at least for my own VISTA System, I was successfully get back to my previous Condition and the usual 10 Minute-ish Booting Up.

I hope the above might help someone in my unpleasant situation.
When making a conclusion you should not use the words maybe, just guessing, i think, etc. you should be sure not to confuse other people.
Go to hell, Delta Search. Your program adds itself without permission and is in fact malware. Ive manually removed it multiple times, and yet it keeps re-adding itself as my search provider.
I too have the same problem Ive already removed it using the add/uninstall and manually changed browser settings on Firefox and Chrome but its shown up again anyone who knows how to remove it permanently please tell me how.
I wish and pray that the programmer of this malware will die from worst accident including his/her families and friends ! !! you re evil ! ! ! go to hell and meet your creator !
still the delta search remained tagged to google chrome. It pops up first when google chrome browser is turned on inspite of spyhunter being there guarding the system
You need to uninstall delta chrome too, beside delta installation (Start->Control Panel ->Uninstall). And change all browser settings.
