Everyone who updated spybot automatically onto the 1.5 ended up with 2 versions. I uninstalled both through add/remove and installed 1.5 alone fresh again. Seems like the best option for that. They really should have made it more clear they were downloading on a new version and told people to uninstall 1.4.
I downloaded Sunbelt shortly after you did to try it out some more. The main problem I had which I did have before on it but forgot, was that it isn't starting to run when I turn on my computer. Leaving me without a running firewall and not noticing. If it is doing that to you, best not to rely on it unless you can always remember to check that it is on. I went back to Comodo firewall.
As for all the other problems you are having I'm sorry to hear. I wish you the best.
