Win32 process error and random ads

[gang2006]

Hi, my computer has been infected via browser, I think, recently. I've tried running Malwarebytes multiple times, both in normal and safe mode, quick and full scan, all came up with nothing, but symptoms remained such as error message saying "generic host process win32" and random ads and random google redirects. Also I've noticed svchost.exe process uses up >50% of memory. any help will be greatly appreciated, thanks.
