Hi - sorry if this is a really stupid question....
I have: Win XP Pro (not SP2 as it made my machine grind to a halt, but I download all other Windows updates / patches as and when they are released) Norton Internet Security 2005 Lavasoft Ad-aware (free version) Spybot Microsoft AntiSpyware beta - all of the above regularly updated and full system scan run
2 mbps ADSL connection (BT)
Over the last few days, I have been getting pop-up messages from Norton IS along the lines of: "A remote system is attempting to access your computer"
Details show: "Protocol: UDP (Inbound)" ""
The dialog box gives me the choice of permitting / blocking this attempt, and as this is identified as "medium-risk" and as Norton's recommendation is "Permit", I have been permitting this
However, although I know that there might be "benign" reasons why other computers should be contacting mine, I'm a little uneasy,as this is a new message I hadn't previously been getting...
My question is this - Am I safe to just click OK to "Permit (recommended)" every time this message comes up, or should I be blocking this? - I'm not even sure what it is (I'm not a techie type!) Does it depend on the IP address shown in the dialog? is there any way I could tell what computer this address belonged to, and therefore whether or not I was happy for it be accessing my local machine?
Many thanks in advance for taking the time to read this and for any advice information you may have
