About a minute ago my computer virtually ground to a halt, which for a P4 1GB of ram, with over 4 GB of recently defraged HD space left is pretty unusual. I solved it by ending the process that had eaten up the most memory (explorer.exe). But this highlights a worry I’ve had lately.
I hear a lot of HD read type sound coming from the computer lately, I could be mistaken and it could be a less than perfect fan, but I worry that there is the possibility that some process is running that is causing constant hard-disk activity.
Yet when I ctrl-alt-del and look at the processor usage it is lower than 5% and not much is happening.
So how likely is it for malicious unwanted programs to be doing some resource intensive task and hiding this fact from the system’s sensors?
