No, no conflicts. Security Scan Plus is a freebie you get when you're downloading other things. Much like the Ask Toolbar or Google Toolbar most people don't realise they've been lumbered with it and we get a lot of enquiries about it. You don't really need it, although I kept a copy around for a while as it was useful to do lightning-fast scans (it doesn't do much except check memory and browser history).
If you don't want SSP just uninstall it in the usual way.
