Browsers suddenly crash when connecting to most sites
The browsers I use (Safari and Chrome) have both started crashing when they try to connect to most (but not all) web sites. I can connect to Amazon and log in with no problem. There are a couple of other sites I can connect to. But for most sites, the minute I try to connect to them, the browser crashes. (Both Safari and Chrome.) I have tried booting in Safe Mode, but the same thing happens. I have Norton products that have run with no problems, but I fully unloaded them (using a command line script in Terminal). That did not eliminate the problem. I have tried disabling the system firewall, again to no avail. I am stuck.
Here is part of the crash report that gets generated after Safari shuts down:
Exception Type: EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Termination Reason: Namespace SIGNAL, Code 6 Abort trap: 6
Terminating Process: Safari [1419]
I have seen other posts to this community about similar issues, but have not found a solution that works. Again, everything was fine until this morning. I don't think I did anything today that would have caused this. I have tried deleting the caches in both browsers, but nothing seems to work.
Thanks in advance for any help you can provide.
