How do I get rid of Adware.SaveNow & Adware.iefeats found from a Symantec Virus Scan?

I can’t seem to figure out where to go next in the Symantec website. I have a really old Norton Anti-Virus 1997. I downloaded the Liveupdate, but I can’t figure out how to open it up and run it to get rid of the detected virus or spyware mentioned above. The Norton Anti-Virus icon shows up on the toolbar and not in the program files via the start button. And, because it’s so old, it doesn’t say anything about updates or any buttons that say repair, fix or get rid of viruses found or anything. Is there a free download that will take care of this problem. Also, after this problem, I downloaded spybot and did a scan there and fixed problems it listed (but I didn’t check to see if any of the above viruses/spywre was mentioned before I hit the fix button. Is there something else I can do other than going through the Symantec scan again for several hours to detect the above-mentioned bugs. Any helpful advice is appreciated. Thank you.
