That's suspect. Looks like malware. The latest service pack level of XP is SP3. There is no SP4.
In Internet Explorer, go to Tools>Windows Update and let it scan your system to determine what updates you need. Then do it from there.
I keep getting a balloon popup in the lower right corner when I start Windows saying click to update. But when I try I get a message saying update to SP4 failed. I went to the Windoows site, but it was unclear about how to update and gave different links for 32-bit and 64-bit systems. How do I determine which I'm using? I have an HP Compaq microtower.
Thanks for any help you can render
