does the very slow window boot-up means i have malware?

Uniblue registry booster is a bogus application.

Google "Snake Oil"  

But then you are still running XP Service pack2 that is no longer supported by Microsoft:

The ones with the "no" entry beside them have been disabled from starting.
There were quite a few, some of them fairly significant memory hogs, such as Adobe Reader, and Limewire.

I know for a fact there are options within the Limewire program to not have it running at startup. Probably the same is true for Adobe, but since I don't use it, I can't be sure.

I wouldn't mess with Uniblue, either.
Ccleaner has a registry cleaner, available under "Issues". If you scan for and remove any found, make sure a backup is kept, and make a note where it is kept (or decide where to keep it yourself) in case of problems as a result. Ccleaner is generally safe to use as a reg cleaner, but sometimes cleans valid entries, in my experience, particularly if the associated program has not been used in a long time. You may notice a slight performance improvement.

I would certainly download the installer pack for SP3, and apply it. (It can later be removed via "add/remove programs" in the event of problems. Problems are generally not encountered.)

After applying it, which will take a few minutes, reboot, and then go to MS (or Windows) update. There are likely to be a lot of updates. At least one further reboot will be required.

Then see how it's all going.
