port scan

hello
lately i have been receiving port scans and connection attempts to my computers port 27374
i mean alot. i use zonealarm pro so theyre all blocked but i have been receiving tons of them sometimes 1 every minute or more for like 10-45 mins straight and they are always from different ip addresses i dont think even one of the numerous times has been the same(i try to keep track of all the ip addresses that scan me, i have quite the list) anyways what is the deal with this, i know that this is the default port for all of the subseven trojan variants but why all of a sudden would i be getting all of these scans for this port. usually its port 80 for people looking for open web servers. the zonealarm security alert pop ups are getting quite annoying, i know i can shut them off but i like to know whats going on. is there some big contest going on on who can scan port 27374 the most or what? is anyone been noticing this at all? i went looking around on my computer for trojans although im careful about what i download and everything gets scanned with norton first before getting opened and found nothing in the registry or various boot files(win.ini etc.) and the start up folder. is there any reason why someone would believe that im infected and would try to scan me for it like something i did without knowing it. I asked this question somewhere else and got the port scans are not uncommon and if zonealarm is blocking it all then you shouldnt be concerned answer but ive been online for quite sometime and never had a wave of port scans to the same port by so many different people before. im interested in computer security so this makes me scratch my head any insights on this would be appreciated

best regards,

thank you for ur post LucF i learn something new everyday however i did both and both came up negative(horay) if u would plz go into a little more detail on these "zombie bots" ive never heard of them- such as if they are connected to a chat server how does that pose a problem i mean if its connected its not holding the port open is it?, how would someone get one of these zombie bots on there puter to begin with- so i know not what to do in the future:), because i do have the 3 main messengers on my machine, i do do regular scans with norton av, spybot s+d, and adaware but its all mostly tracking cookies they ever find and norton has never found a virus on here well except when i tested it with the eicar test string. just while typing this i had 4 alerts all for port 27374 this is gettin a little rediculous. its weird cuz the port 80 scans dont even happen very much anymore like they used to its all 27374 now. this puzzles me also another question in netstat i have 9 times of local address of 0.0.0.0 listening to various different ports all of the foreign addresses are 0.0.0.0 as well can someone plz explain this to me i think i read somewhere once about my computer listening to other parts of my computer- does this make sense i dont wanna sound dumb but the only way for me to learn is to ask someone that knows. just for giggles here r the 9 ports 135, 445, 1025, 1026, 1027, 1033, 1512, and 5101. wow another question i have now after looking at netstat some more all of the ones i just listed are using the TCP protcol however i have 7 more local 0.0.0.0 doing something with different ports but all of these are using the UDP protocol and it doesnt give a foreign address or the state of it -listening or established, what is the difference between the TCP and UDP protocols there is also 3 more with the local address of 127.0.0.1 doing something with ports, now i know the address of 127.0.0.1 is the local address of my computer but what are they doing
wow ive written alot here alot more than i was planning on. if someone wants to sit down and type all this stuff out to me that would be great. i really like this stuff and i can never learn too much. if someone wants to take the time to type it all i will up the points for this question. also after all of this plz dont forget the origina question of the port 27374 scans as im still very curious on it and would like to know what i did or how to make it stop if there is such a way(i doubt it but u guys r the experts not me) ;)
ur help is appreciated in advance
