I'm posting about my experience today with "ATDMT.com" interfering with my online usage, locking up my computer while I was trying to address and send an email via earthlink.net.
I was waiting for the email program to load and after a few minutes I noticed that this address beginning with ATDMT.com was controlling my computer and exercising the hard drive to the point that nothing else could load. So I just unplugged the comm line and it stopped, of course. I was concerned because it looked to me like some kind of virus that was downloading all of the data on my drive. Turns out it was doing just that, copying my usage history. After googling ATDMT.com, I found that other users had the same complaint, asking for help defining exactly what it was. some forums said it was harmless while others gave advice on how to block it. A few of the concerned users were on this site, that's how I was led here and decided to register and post because there seemed to be a number of conflicting opinions on ATDMT.com activity. Personally, after seeing the way it locked up my computer today, I'm looking for advice on how to completely block it and all of it's variants.
If anyone has anything to add I'd appreciate hearing about it.
