I use Spamfighter and pay each year to renew it. To me, a layman, it seems quite good. It urns up lots of supposedly-harmful stuff for me to delete.
But I find an odd problem. I update it and use it without difficulty on the first occasion.
But it frequently goes missing on the second or third occasion that I use it- esp. the full Disk bit.
So I have to go through the palaver of uninstalling and reinstalling in order to make it work.
What am I doing wrong? It shows as 'there', true, but it then refuses to do anything when I click on it- hence I now save the 'uninstall and reinstall' link.
Can you assist?
