Hey

Will need some more details to help you out completely but from what you have written..

Unauthorized log access - The exposure of the log files to potential modification does not in anyway affect the security of the product. File modification merely provides a potential way for an intruder to attempt to disguise their illegal activities.

P2P Networks - you can very delete the P2P Networks but I'll have to know what kind of networks are being used on your computer.

ICMP Ping - Internet Control Message Protocol, ICMP is used for error and control messages on the internet. It simply means the network is pinging your computer to check if you are connected to the network at periodic intervals. This sometimes may be abused by the hackers so its better to block it off.

As you said Symantec online scan shows your computer is open, which means your computer is visible on the network / internet which leaves it open for hackers to abuse. The simplest of solution is to get a firewall, I use ZoneAlarm which can be downloaded from Zonelabs.com and is highly recommended. Its very easy to use and configure and works silently without using too much of resources. It also hides your computers on the networks and the suite version also has an Anti-Virus with it so you may just get a single product once your norton expires till then use the free firewall version. After installing the firewall you may run the online scan again to make sure its well configured.
