Disable Windows Messenger pop-ups?

Not long ago, I received an email from 'Rezzy46', who has been plagued by a new form of spam: Windows Messenger popup advertisements (note: these are not MSN Messenger chat pop-up messages).

It is designed specifically to work with ... (view more)

Yes -- this is a ... very technical question, but certainly very worth-while to know the answer to. Here is what the connection might look like if it was daisy chained: Internet connection -> Router, 1 port [hardware firewall] -> Desktop PC [software firewall] -> Laptop [no firewall: is it protected from the Desktop PC's software firewall?] This type of daisy ... (view more)

I was planning to continue my ongoing discussion on Disk Imaging in this issue of the Gazette, but my mail box has been inundated with emails from folks who have fallen prey to a chain-letter virus hoax.

FriendGreetings.com -- Helping to send Spyware to loved ones

Did you mail all your Christmas cards out yet? I've got a small collection starting on top of the mantel, but I'm surprised that I haven't received any (tangible) Holiday cards yet from Infopackets Readers! Sending an e-greeting is nice to receive, ... but it's hard to differentiate the spam mails from the legit. Sometimes when I write a newsletter, I get up to 200 emails in a day! That can get kind of nutty after a while. And, that brings me to my next point. MBMaser emailed me the other day and told me about a web site called FriendGreetings.com which is allegedly responsible for incorporating ... (view more)
