1) Can’t get emails
2) Sends almost everything to the spamkiller folder
3) You get javascript errors all the time (at least 3 or 4 before you can view a webpage – even if the page has no javascript on it)
4) It slows your computer to almost a halt

Solutions to anyone suffering the problems:

1) Turn SpamKiller off, completely. It is the slowest piece of software on the planet. What happens is it is soooo slow that your server will time out (I had my settings set to 5 minutes for timeout). You will have got one or two emails, but because the server timed out, you haven't deleted them off the server, so next time you get the same emails again and then it times out, again not deleting them.

2) Everything that it does pick up goes to the spamkiller folder - the settings are too high and it is too slow. Turn SpamKiller off. It resets all your settings when upgrading.

3) JavaScript errors are caused by SiteAdvisor (mainly affects Firefox). Turn SiteAdvisor off unless you need to use it for a specific site (i.e. to check a bank)

4) Slows to a halt - go through and turn most things off. Leave Virus protection and Firewall ON! Decide if you need the other things and disable if you feel appropriate.

VERY annoying bugs in this software. Easier option is to not upgrade yet until these are sorted (the upgrade pops up on the screen and is free).
