Not an expert on this but I'm not aware of any software buddy but I know that bcos there's been invalid clicks on ur account Google should pay more attention to it. I know someone this happened to and he said he's not been banned again by Google after he explained the situation and they analysed his account.

This is why you never reveal your adsense sites in forums, ever.

I would think that if anyone would know the answer to your question, it would be Google. Why don't you ask them how you might be able to prevent this from happening again. You would think they would be happy to help you stop fraudulent clicks on your ads.

Just out of curiosity, I went to Google to see what would come up. Looks like there is a few items listed. Not sure if any of them work.
stop fraudulent adsense clicks - Google Search

thanks for the input

I got banned years ago. I never knew the reason other than they said Ilegal activity.
Certainly not from me. I tried a few years later and they wouldn't accept me.
I think my orginal site earned about $75 over a few months, I of course lost that.
I smell a rat.
