that's strange as I also have Acrobat Reader 6 on my computers and never had a warning like your friend has. I would say, it would be much better to post this message in the Wilders.org forum, as Javacool (the author of the program) can answer your question directly.

My friend asked me about BHO found in SpybotSD by spywareguard. Should he remove it or keep it. Since I'm not sure how to answer the question, I posted here.
First he install Spywareguard 2.2, then SpybotSD. On spybotSD installation, Spywareguard give a warning that it detect a BHO, and ask if he want to remove or keep the BHO found in spybotSD. (he also mention that spywareguard found BHO in Acrobat reader 6, during acrobat reader installation)
The question is, should he remove or keep the BHO, on both application (SpybotSD and Acrobat Reader 6)
