FYI: catchme is not a problem. It is due to you having run Combofix last December.

And your PC is slow because of the system specs. It is a slow processor and you do not have enough memory to run Windows 7. In fact you have so little free memory that your PC will be extremely slow. From your logs.

Code:

Processor Intel(R) Atom(TM) CPU N270   @ 1.60GHz, 1600 Mhz, 1 Core(s), 2 Logical Processor(s) 
 
Installed Physical Memory (RAM) 1.00 GB 
Total Physical Memory 0.99 GB 
Available Physical Memory 72.6 MB 

You need to added another 2GB of memory.
