Ok.. So, I suspect that I have a trojan hidden away in the depths of my computer somewhere. So, I am running all the suggestions here. I just tried to run Ad-Aware (again), but the computer starts making the worst beeping noise ever, and wont stop. Finally everything freezes up, and I have to switch off the computer.
It seems that whenever a lot stuff is loading up or running, it starts beeping again. I have hoovered out the back in case it was something overheating 'cause of dust, I have made sure everything is connected properly.

Dust & CPU Freeze (Hardware point of view):
__________________________________________
Your CPU when at 100% is generating lots of heat - - -
Thats OK it is designed to work this way

However if you have a lot of dust build up in your case - - -this causes problems

You said that you cleaned your computer . . . . .did you inspect your CPU - Heat Sink & Fan assembly for excessive dust buildup?

Your CPU has a heat sink which is dissipating the heat & there is a fan on top to force cool air down thru the fins & out the sides - Usually the fan is Temp controlled & runs faster as Temp rises

But if your heat sink has collected dust in the fins - - - it is clogup & cool air is not passing thru to cool down heat sink & dissipating any heat

Some have heat sensors & sounds an alarm. . . such as beeping

CPU circuitry will shut down the CPU to SAVE it. . . .Thus you see freeze - no mouse - no keyboard

Check & see if your heat sink is not clogged

This problem gets worse over time . . . .

You can enter your BIOS and tab over to CPU monitor and your CPU Temp is measured + your voltages CPU will shut down over 85 C

If your heat sink is clogged . . . .you can use a can of Cleaning duster
(High Pressured Air) . . . . . Just read the instructions:
DO NOT INVERT CAN OR SHAKE CAN!!! High Pressue Air turns to LIQUID when inverted . . . . BIGGER PROBLEM

You want to clean the fins out . . . .if it is really bad you can pick most of it out with very fine tweezer first before spraying

You may have to turn computer in different quadrants to keep can upright . . .OF COURSE COMPUTER IS OFF & DISCONNECTED)

When you cleaned . . . . . . was there a lot of dust?
