Hello! It looks like you may be infested with Spyware also known as Adware. There is no need to panic, as several easy-to-use tools exist to aid you in removing the spyware. What is spyware, you may ask? Spyware or Adware commonly tracks your browsing patterns and sends data back to advertisers. It is a security and privacy risk, and should be dealt with immediately. To remedy this problem, you have the choice of 2 programs to download. 1. Lavasoft Ad-aware (Download here) The leader in spyware removal. Once downloaded and installed, it is recommended to update the built-in spyware scanner by selecting "Update" on the main screen. 2. Spybot-S&D (Download here) Said to clean your computer more thoroughly, it is best to run Ad-aware first and then run Spybot afterwards to remove anything Ad-aware didn't pick up. Pertaining to your specific problem: I have hex edited the attachment you made (which I assume should have a .dll extension) and have found no reference to anything worthwhile. It appears it is either self-replicating, or called by an external program. I recommend an in-depth spyware scan. If you have any more problems or would like to add to your problem description, please, don't hesistate to post! Thank you for choosing MSFN.
