I've had so much trouble with that ilivid thing as it also put a toolbar on my computer called searchnu.com which was impossible to remove despite un-installing it as it kept reappearing! Today I've downloaded Microsoft Security Essentials (was using AVG free) which is a free download (came out best in the Which magazine) and it found 4 threats, two were serious.
Its removed that search engine and also the other threats (two of them came from Java) and l've also changed my passwords so hopefully l'm safe now!
I'll be much more careful in future.
