Reading the DT technical questions someone asked about issues with Delta Search and difficulties getting rid of it.
The DT recommended AdwCleaner -goo.gl/CMnbgb
This is foc to download.
MY PC does not have Delta issues but was sometimes hesitant and threatening to hang occasionally.
Downloaded and ran the above..............what a difference.
The software ran in a minute or so. Rebooted PC and the issues I had disappeared and now runs much more quickly.
The DT article warns against downloading the AdwCleaner product from other sites as they can be infected.
People would probably prefer something like a FileHippo or the original website for the software link than anything from the LA press.
The Telegraph really is in the pan these days.
