When you visit a FTP site, that site is added to the MRU (most-recently-used) list. This is most likely not malware. I am 99.5% sure that this was not added by ant malware, but someone just click on a link somewhere. You can use CCleaner
to remove the MRU lists or if you would like to remove just the one URL from My Network Places, simply right click on it and choose Delete.
The URL that you posted "ftp://ftpez.ca.com/"
is as Rarehunter stated for EZ Armor antivirus from Computer Associates. The site is registered to them and appears to be completly legitimate. Like I stated, it is very possiable that someone clicked on a link to the FTP site adding it to My Network Places.
