Issue 2463: python.exe slowing my system

Hello!
First of all, I'm nor a programmer. 
Running WinXPpro.
Python.exe runs, using 112,000k mem, according to task manager. 
This problem started about 3 weeks ago, have had machine for 3 years
without issues like this. 
Please help me make this problem go away. 
How do i figure out which program is using python, do i even need python
on my machine?
Thank you in advance.
