How to uninstall antivirus program on Mac Air please
Hi I have Mac Air OS X 10.9.4 and wanted to download McAfee antivirus program which requires removing my now defunct Sophos Antivirus. I have removed all Sophos files (per my computer) into the trash but still am told McAfee cannot download because there is still an old incompatible antivirus program. Please help. I am now unprotected. There is a Sophos "logo" in the tool bar but I don't know how to remove it...and it will not function when opened. Thanks much!
MacBook Air, OS X Mavericks (10.9.4)
