Top Arcade Hits and inksdata troubles

Hello,

I became infected with these 2 buggers on or about Aug 8th, seems they came in with a file conversion program trial version. They create annoying popups and extra tab and/or page openings quite often, some page links won't function at all, some do. I have not identified any other freeloaders as of this time.

One thing I have noticed is that an older Yahoo mail page no longer bears the security logo I had made. Could it be coincidence or an action by my unwelcomed visitors?

Any assistance you can give me would be greatly appreciated.
Thanks in advance,
digit
