What have I done...?

Tweet

After I saw that I can put myLot as my default search engine, I being to use it as any search engine, but after about...a half an hour/an hour this message it's coming across every time I try to search something:[in the photo]. Why is this message coming across? I haven't spammed or over used it...I just used it the way I use Google search... Also I haven't tried to hack or something like this. Please help me with a little answer about this. Thanks in advance!
