I am not sure if I should install SP2. I checked for spyware with Adware and I get some scary looking things that say Alexa. They look like they could be harmless but I won't delete them because I don't want to mess with the registry. Any advice?
It's been on since XP came out. Deleting it with ad-aware will not cause problems. Major patches like service packs may reinstall it, but otherwise, it won't come back. It's what provides that 'show related sites' buttom in internet explorer.
We encountered a similar situation while working on a chatbot development project. The popups are actually required caches that are stored by alexa and its not harmful. I suggest you keep it as it is and continue with the project. As a chatbot development company, we have come across several such issues on multiple occasions but it has never hindered our development project.
