Norton firewall started blocking Chrome

I just tried to open Chrome on my Windows 7 PC, just like I have every day for the past year (or however long it's been since Firefox and Norton toolbar stopped playing nice). Norton firewall now pops up saying Chrome is not trustworthy since it's less than a week old, has very few users, and is unproven. I know that Chrome updates itself all the time, but have a hard time believing the there are less than five users. Even if it did just update itself this morning, seems like the trustworthiness and user base would build to the thousands within a matter of minutes, considering how widely used it is. Just wondering if anyone else has seen this behavior just today.

Re: Norton firewall started blocking Chrome

That sounds very odd.  I have the latest Chrome update and have not encountered this at all.  Have you clicked on any unexpected popups asking you to update anything lately?

Nope, never click on any popups. Also I've not made any recent changes to my router setup configuration. I've tried opening Firefox and IE, and neither shows this behavior. The "info" popup on the Norton blocking screen shows the normal, expected path to chrome.exe.

I'm showing similar stats, except for the number of users. I also have two file thumbprints; the SHA is very different from yours, but I assume those are machine-specific.

Re: Norton firewall started blocking Chrome

Just a quick update:  Today NS firewall is still blocking Chrome, but now instead of saying fewer than 5 users it's saying fewer than 50 users. Very weird. It's like Google randomly distributed a few updates with a slightly different executable that Norton doesn't recognize. I've never heard of that, but I guess stranger things have happened. And again, I've never seen any suspicious popup messages, let alone clicking on them. I guess first I'll try uninstalling then reinstalling Chrome since that will be slightly less time-consuming that removing and reinstalling NS.

Maybe, try Firewall Reset and see Smart Firewall/APC create new program control rules.

Or, remove Program Control rule for Chrome and see what Smart Firewall does upon call Chrome.

Re: Norton firewall started blocking Chrome

I ended up removing and reinstalling Chrome, but since I was in a hurry at the same time I reset the firewall. Not sure which action fixed it, but Chrome and Norton security are playing nice again.

Re: Norton firewall started blocking Chrome

This problem just popped up for me, too, today. Norton simply blocked Chrome.exe today. Norton indicates that only 50 users have tried this new file. Very strange.

I'll try removing Chrome and reinstalling as Rocket Scientist did. If that doesn't work, I'll reset the firewall. Then report back.

Re: Norton firewall started blocking Chrome

It worked. 

I thought uninstalling Google Chrome would be time consuming, requiring a lot of HKey searches, but I simply went to control panel, on Windows 7, double clicked to uninstall.  At the end of the uninstall, Google asked if I'd like to reinstall. I did. The whole process took 1.5 min. And now Norton Internet Security will allow Google Chrome to access the internet.  I didn't reset Norton's firewall. Everything works. Thank you Rocketscientist.

Re: Norton firewall started blocking Chrome

That is interesting, and puzzling. So I guess Chrome was at fault, not Norton. Like I mentioned, it's almost like they randomly distributed a different update to a very few users that Norton didn't recognize. I have no idea why they'd do that.

Re: Norton firewall started blocking Chrome

@rocketscientist: I did the following tests:

1. disable Chrome's gupdate and gupdatem; install a trial, old version (build) of NS; ran the OFFICIAL Chrome client .

(To check Chrome version info, simply enter chrome://version in the address bar, press Enter.)

NS popped up nothing nor blocked Chrome, and wanted me to install Norton Security Toolbar instead.

I ran Chrome as the admin user: the result remained the same.

2. I update NS first (meantime, I keep Chrome as it was; and I did not make any changes to NS, nor to my Windows 7) > follow > restart my computer > run the old Chrome.

3. I tried running the old Chrome (even using the admin access) but no luck - note that I could not update Chrome either. Norton sent me nothing. Something (process, personally) did flash, but I could not catch it.

  • NS: 22.7.0.76
  • Chrome: 47.0.2526.80

Then, I disabled Auto-protect > tried running Chrome; not worked > disabled Smart Firewall > either; re-enable Firewall > looked into Program Control - Chrome was allowed to run (and to access the www , I think).

(Note that the 2nd Google Installer (GUM623.temp) was grayed out. Is it the problem-maker?)

This time, I blocked all the 3 Chrome-related items; nothing happened either.

4. Re-updated NS > restarted > re-ran Chrome when I entered my desktop > Good to see my Chrome (Chrome updated itself automatically when NS performed the automatic update.).

  • NS, 22.7.1.32
  • Chrome, 53.0.2785.116

Then: I personally guess NS (v22.7.0.76) and/or the said (old?) NIS was at fault. Please feel free to correct this comment.

Now you: could you please provide us the original install path for your Chrome? What was/is the version info of your NIS?
