Post subject: Problem with DoS Attack - RST Scan and remote access

I am having issues with DoS Attacks - RST Scan / IMAP Scan / FIN Scan and remote access to LAN from ip's from other countries. My OS is Windows Ultimate and I have Ad-Aware, MS Security Essentials, Avast & SpyBot, PeerBlock installed on my system.

My Wireless Router is Netgear WNDR3700 and setup a log to send to my email every hr. Other than my laptop, a NAS drive and an IP cam device is connected to the router.

I have setup a DynDNS.org hostname and it is given on the router , NAS drive and ip cam device. When I send email to the Lacie (NAS drive) support, they told me to disable the automatic port forwarding on the drive.

Any advice on this issue? Any additional softwares to be installed or any extra preventive measures to be taken?

Router Log follows:
