Limiting the processor drain for AVG?

Hi Dean,
Thank you for choosing AVG. The minimum requirement for AVG to run smoothly is an Intel Pentium 4 / AMD Athlon 64 processor or above (must support SSE2 instructions). It is mandatory that AVG services run continuously to protect your PC.

I just installed AVG basic on an old Vista machine.

Unfortunately the Vista machine has a processor that overheats if I put too much of a strain on it.

Is there a way, within AVG, to limit the "pull" on the processor?

Thanks in advance.
