Norton warning for unsafe site while site is safe

Post by matthijs »

Not sure if anyone can answer this, but if I google on words related to this question I only get thousands of results with sites trying to sell me Norton (come on Google, you can do better than that!).

Anyway, a client called me to say his Norton program warns that his website might not be safe. I checked the website and can't find anything suspicious. Can this be a false-positive? Does anyone know where I can find more info? Some general computer/security forum maybe?

"depending on the site, it could be triggered by an ad from an ad network that contains possible malware"

There are no ads on the site. The only script on it are 5 lines of simple javascript and google analytics.

In the meantime I discovered that its possible to submit a request to Norton to rate the site and put it on a white list. Quite the hassle. Maybe I should sue Norton for falsely scaring customers away from my sites

Is he using shared hosting? it's possible the server he is on or the domain he is using has fallen into a blacklist for spam / malicious activity by another user on the same server.

It may be the IP is flagged as a malware threat especially if its on a shared server. You can try adding the site here for review http://www.google.com/safebrowsing/diag ... google.com

@Benjamin: good idea. Didn't know that safebrowsing check from google. Bookmarked

@pytrin: yes, shared hosting. I'll see if I can find anything

To be clear: the website is not flagged as dangerous, but as "unconfirmed". So visitors using Norton would see a question mark or something. I haven't seen the exact message myself, since I don't have a PC with Norton to test with. But it seems that every site that is not yet whitelisted is marked as "unknown/unconfirmed". Most of them will turn out to be safe. However, to a visitor seeing such a question mark instead of a green checkmark for "safe" already looks suspicious.
