there was a program I had a while back, it was a bunch of tools in one program. I can't remember the name of the program, but one of the tools was something that you could check off to prevent anyone from pinging your computer. If I understood that software right (Im not a techy by any stretch of the imagination) it would or could prevent someone hacking into your computer, by preventing them from pinging it. It seemed like a good thing to have, but I dont use it and haven't for some time because the overall software package was kind of buggy, and sometimes the pinging part wouldn't work right. I wish I could remember the name.....but I wondered if PcWinTech could write such a program or even if he has one already. Just a thought, I think this would be a good security program to have. Thankyou.
