If you switched to Linksys from D-Link after seeing HNAP1 in your logs or after reading the article, you should now make sure your Linksys equipment are protected properly from worms as scans for tmUnblock.cgi are being done now.
Since the device that I use in my testing lab is a Linksys WRT150N Wireless N Home Router v1, I went to DD-WRT and downloaded their firmware and flashed it for additional features one of which is to make it a 2.4GHz repeater.
