I recently underwent a clean up process with support on this forum.
At the start of the process i was having problems with BT Netprotect (McAfree). Following the clean up I am now using Avira Free edition (McAfee was removed). Today I found that McAfee had somehow 'reappeared' on my machine. Looking in control panel it said it was installed today. I then uninstalled it in Add/Remove programs.
Avira advised me that it had prevented somethng altering the hosts file (i guess it was McAfee trying to do that).
Im concerned where McAfee came from and how it got back on my machine.
Id really appreciate any advice. Should i be concerned?
