Hey, I have noticed “ads by Download Offer” pop-ups and googled this line online. I have found and read your report about ads by Download Offer, and it was very informative. I did not know for what files I should look in the Control Panel to uninstall this intrusive program, so I thought that anti-spyware will help me to remove Download Offer ads easier and quicker. And I was right! SpyHunter detected this and PursePerks programs and also removed them successfully. Thank you!
