Was it a USB DSL modem? Could be drivers. You probaly don't need it anymore though, can uninstall it.
I was looking through my control panel and saw that there was a program I have never seen before in the Programs and Features called "ATT-PRT22" I have already tried searching it on google and found little results.
I am wondering if it might be a program for comcast internet (I recently changed from ATT DSL to Comcast)If anyone can help and tell me what this program is for and whether I should uninstall it, I'd appreciate.
