Safari randomly opens with a blue magnifying glass application

Hi everyone,

So about four months ago I started to notice that safari keeps opening randomly, downloading with it each time it opens a blue magnifying glass application (the application image is a magnifying glass) and I was wondering how I could fix this problem.

It could potentially be a 'helper' that safari installs in order for it to run efficiently, but I suspect it's some sort of virus, because recently one of these helpers was downloaded, named 'Deafult...'. I forgot the entire name, but the misspell of default as 'Deafult' has led me to believe that this is some kind of malware.

Help regarding how to get rid of this problem is greatly appreciated.
