I was just browsing on the internet and a Norton window popped up and said - you need to restart your computer to remove security threats - which I did but I cannot find any information on this in any google search or anything that relates to a security threat on my computer that needed to be removed in the Norton Security Suite logs - I'm concerned it was a virus posing as a legitimate Norton window trying to get me to restart my computer
Hi micksuder, and welcome. In the Norton UI, you can click on History, and in the drop down menus there are various options to check.
When you find the one you're looking for, on the right had side, click on More Details for extra information.
Let us know what you find.
You can also right click you tray icon, and check recent history.
Hi mickstuder,
In the drop-down menu mentioned by F4E, please in particular check these two info categories:
Resolved Security Risks and
Unresolved Security Risks
and let us know if they show anything related to the event.
Hi, mickstuder; welcome to our community.
If you don't turn up anything by digging deeper into your logs, I would tend to share your concern about malware. You might want to try downloading and running the free version only of malwarebytes:

Don't let it remove anything; just run it. Malwarebytes isn't as good as Norton at keeping nasties off your machine, but it has a knack for still being able to find & report them even after a machine has been compromised; if it finds anything, you'll want to go to one of the specialized "removalist" forums, to work one-on-one with an expert who's got special training and tools to pull the things out by the roots:

Good luck, and keep us posted--but once you open a case on a removalist forum, you should not return here or talk to anyone but your assigned removalist until they tell you they're done.

Hello
Thanks for everyones help and input - when I dug deeper into the Norton Logs - I found that the Hachilem Trojan had been detected and removed............................I am using a free Norton Internet Security Suite offered by Comcast and I've often wondered if this free version from a Cable Co. was as effective as the purchased versions. At least in this instance I guess it is!
Thanks for letting us know the details. Yes, Norton Security Suite is a full-fledged Norton product, just customized a bit for the Comcast partnership. @yank can tell you more; he's our resident expert. Don't think of it as "free" (and therefore likely restricted in some way); think of it as paid for (subsidized) by all that money you send to Comcast every month!

Hi mickstuder,
Since you asked about the Comcast Norton Security Suite (NSS), the following URL will display the difference between the Reatil N 360 and NSS.
http://constantguard.comcast.net/norton?cid=NET_33_601
You will notice there is a difference in the Backup Area - as there is no Online storage associated with NSS - although you can BackUp to a external source.
Also another difference not covered in the comparison is that the NSS Identity Safe Vault is in fact a Local Vault and an Online Vault is not available. For those users who dislike the Online Vault and prefer the Local Vault that is a plus - for those users who desire to tie thier ID safe log-ins to mobile devices it is not a plus.
In regards to protection, definitions etc - the retail and the Comcast versions are all the same. Sometimes you need to wait a bit longer for an upgrade (as in version 20 to version 21) to be pushed to NSS, but IMHO is not all bad. Lots of users wait until an upgrade has been out for a few weeks (to see if all is working properly) before applying it to their systems - so basically Comcast is doing that for their users! 
Any more questions on NSS - let us know.
