How does your mac running now, if you still have problems with ask.com or other similar? You had an Infection by a Variant of Genio Adware, AdwareMedic has removed it.
MacKeeper is a scam you should remove it. As I see it is still on your System. I'm not sure why DetectX not remove it.
If you still have MacKeeper in your Applications Folder, Quit the MacKeeper and drag it to the trash. Confirm do you want to remove it.
Again Important: If you using the encryption feature of MacKeeper decrypt the files first because you cannot do it later!

Your Question about Antivirus
Read this Article please and take your choice: Mac Malware Guide : Do I need anti-virus software?
I cannot recommend any AV-Solution because every Solution has it's advantages and disadvantages. The mac has innately protection solutions with Gatekeeper and XProtect (also known as File Quarantine).
Every protection solution take system resources and sometimes the system slow down because every action do you do on your system (copy, move, download, open and so on..) the av solution scans in the background. I have doing good experiences with Eset Cybersecurity, ClamXAV and Sophos Antivirus Free for mac.
