Could be worse...
NIS automatically deletes any download its database hasn't encountered before, whether malware or not. In doing so it claims that the file was 'suspect by reputation' -Which would seem to be dangerously close to grounds for a libel action. Or, possibly a USA class action by affeced coders. Now, that could be majorly expensive. I'm surprised Symantec haven't considered that risk.
McAfee Site Advisor allows members of the public to rate websites as benign or malicious, and is robot-friendly, judging by the many thousands of identical troll postings. Again, allowing trolls to use your system to defame websites in-bulk could be very costly, in a legislative sense.
Eset recently gave a false positive on one of our downloads. This caused it to automatically delete a security utility, leaving the computer in a state where no new software could be installed. Uncertain how many users were affected but it certainly damaged our reputation as coders, and though no fault of ours.
Basically the whole anti-malware business is in chaos. Key problem is the desire to cover all eventualities, while at the same time to present a 'dumbed-down' interface which makes all decisions without asking the user's OK. Now, the software is bound to get it wrong sometimes, but it's when the human is taken out of the loop that the daft decisions really cause damage.
As for Google Analytics, if the site loads third party content or stores a third-party cookie there are at least grounds for suspicion of unethical actions.
