No, it's not an XP program and no, it probably isn't OK to run.
Go through these general malware removal steps systematically -

Include scanning with David Lipman's Multi_AV and follow instructions to
do all scans in Safe Mode.

When all else fails, run HijackThis and post your log in one of the
specialty forums listed at the link above (not here, please).
Standard caveat: If the procedures look too complex - and there is no
shame in admitting this isn't your cup of tea - take the machine to a
professional computer repair shop (not your local version of
BigStoreUSA). Please be aware that not all local shops are skilled at
removing malware and even if they are, your computer may be so infested
that Windows will need to be clean-installed. Have all your data backed
up before you take the machine into a shop.
