What is Lasaoren?

Lasaoren (also known as Lasaoren Search, WSE_Lasaoren, and Lasaoren New Tab) is a potentially unwanted program in the adware and browser hijacker categories of computer threats. This program uses browser add-ons and extensions, as well as browser helper objects (BHOs) to change existing internet browser settings, such as the homepage and search engine, as well as display targeted advertisements across multiple internet browsers.

  • Dear Sean / botcrawl,

    I rather stupidly downloaded ‘Lasaoren’ masquerading as a Firefox upgrade.
    Using your guide I was able to rid myself of it.
    The pleasure I gained from sticking a metaphorical knife in it’s back was immense.
    I feel as though I have been cured of a nasty disease.
    I wish you a long and happy life filled with fun, friends and great sex.

    All the best
