BCHelper.exe - Browser Companion by Blabbers Communications LTD
What is bchelper.exe?
DefaultTabSearch.exe is a part of the BrowserCompanion PUP/Adware. It's not essential for Windows and may cause problems, for example slow down your computer or displays the following error message at Windows startup "BCHelper.exe - system error". Very often this happens because sqlite3.dll is missing or corrupted. What is more, this program runs in the background and periodically checks for updates. It may display advertisements on your computer and download additional adware/spyware onto your computer without your knowledge. It may also collect information about the website you visit and things you like. Later this information may be used to deliver targeted ads to you while you surf the web. ESET, Trendmicro, Malwarebytes and some other anti-malware programs detect this program either as adware or Trojan generic. Usually, it's detected as Win32/BrowserCompanion.A or PUP.Blabbers. I recommend you to remove BCHelper.exe from your computer.
