A new Toshiba Satellite C50 laptop and already problems

It looks I have inadvertently uploaded some bad stuff.

I was trying to do the right thing and downloaded nites, startup, CC cleaner and PC decrapifier.

in doing so my searchdial toolbar has attached itself to avast, which I tried remove in favour of adware,

something nasty called websteroids has been downloaded.

try as I have I haven't been able to removethis malaware

how can I do so?

advice greatly appreciated!

Download Malwarebytes. run that to knock the malware out. I would also recommend using Revo Uninstaller to get rid of unwanted software. Works a lot better the PC Decrapifier and the uninstaller that came with windows.
