Norton Firewall slows computer, crashes web tabs

New Windows installs on 2 x virtually identical Dell laptops, Windows 10, i5 dual core, 16GB ram, SSDs, display the same problems - often web performance not as you would expect, especially slow loading pages, tabs often seeming to crash (no response when clicked) overall just very slow and frustrating to use. Re-installed Windows 7 in desperation as felt it may be due to the fact that time had caught up with these 2011 laptops!. Tried all sorts until it was suggested to turn off Norton. Turned off the Norton firewall and turned on Windows firewall. Hey presto, computers both behave as would be expected, stable and fast page loading, no tabs crashing for the last 7 days. I guess I may try and figure out if there is a part of the "smart firewall" that's being a bit dumb, but tempting to just leave it switched off - I love the password manager but don't really care about the rest of NIS

Re: Norton Firewall slows computer, crashes web tabs

Hello

Welcome to the Norton Community Forum

You neglected to tell us which browser you are using, what version of NIS you are using.? Did you try using the Remove and Reinstall Tool on the Windows 10 before you got desperate and reinstalled Windows  7? Did you try a clean install of Windows 10 before you got rid of Windows 10?

Have a Good Night and

Thanks.

Success always occurs in private and failure in full view. Windows 7 Pro 64 bit NSBU 22.17.0.183 Core Firmware 282 I E 11 Chrome latest version.

Re: Norton Firewall slows computer, crashes web tabs

The problem was the same with Chrome and IE. Using NIS latest version 2018. I thought at first it may be due to Windows updates making the hardware more and more obsolete, both laptops had relatively fresh clean installs of Win 10 Pro.

Also, I noticed Gmail incredibly slow and buggy until I turned the NIS firewall off. I'm quite amazed but it does remind me of about 10 years or more ago when Norton was notorious for slowing computers down. After that they did improve their act and I have had no problem I know of since, until now.

Not sure how this post displays on the forum but I did select I don't need help as such, I posted more as a record that someone had found this scenario to give others ideas if they have the same symptoms.

Many times a user comes here to just give feedback. But sometimes they have not exhausted all avenues to try to find a solution to their issue. That is why you still get feedback and suggestions.

Just wondering how you were able to turn on the Windows Firewall while you still have Norton installed. Normally, Norton disables the Windows firewall to prevent conflicts. How do you know that the Windows firewall is actually active and maybe you have no firewall jprotection at all. That would account for the performance difference.

Things happen. Export/Backup your Norton Password Manager data.
