Dxdiag says "478mb RAM" and "~1.6ghz processor"
Did you get these numbers from System Information? What is the number for 'Total Physical Memory?'
but i've been told that because my processor is dual it means i have double this...
This is not true.
e.g. Task Manager says 1121 Mb of ram and so does dxdiag under "page file" so there must be some truth to this.
I don't know what you mean by this but it has nothing to do with a dual core processor or your physical RAM.
Also, what are your harddrive numbers: total and free space?
With regard to your security programs, I am not familiar with Mamutu so I don't know how 'heavy' (how many system resources it uses) it runs; but, if you don't run AVG real-time (and I would suggest that you re-consider this; in fact, I would suggest that you uninstall AVG, if it is version 8, and replace it with Avast! and run it real-time), Windows Defender and Windows Firewall ought not slow down the computer.
Given the above, if it were my computer that I 'felt' was running 'slow' or 'slower than before,' I would: a) download and run CCleaner (but not the Registry Tool) and make certain that it was set to clear all temp files and index.dat, b) do a virus scan, c) download and run run a scan with SuperAntiSpyware, d) defrag, e) purchase RAM to total 1 GB. You can also try running with Mamutu turned off to see if that helps.
Best of luck!
