Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.

    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.

    dont forget to do the last step – in the onstart menu, it took a minute to find it but it solved the browser opening to delta over and over problem!

    i innocently tried to load a pdf manual for my blender. i was excited and loaded the first google searched link. what a mistake!
    if you need manuals – be sure to check that you are on the actual manufacturers webcyte!

    thank you for posting this page. it took me about an hour – but i rid my computer of that nasty sneaky trickster!!!
    shame on them for making their browser look like the google page.

    thanks again!!

    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.

    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 :).
