This PC is getting very sluggish, even though it is only used for 'light' duties, email, web etc.
Windows 7 Home Premium
AMD Phenom 8400, 2.10 GHz
so the core parts are from 2006/7 I think.
I spotted this

Image Path Name : C:\windows\system32\lsass.exe
which seems very high, considering that it is only running on 2GB,
The PC is behind a router, has up-to-date MS security essentials, the uptime is about 2 days.
I remember that LSASS was involved in the sasser worm,
but most of that stuff has surely been long fixed.
Could it be a malware hijacking lsass for it's own purposes? Or just a memory leak?
It could probably do with a bit more RAM nowadays, but something else must be going on as well.
SFC comes up clean too.
C:\Windows\system32>sfc /scannow Beginning system scan. This process will take some time. Beginning verification phase of system scan. Verification 100% complete. Windows Resource Protection did not find any integrity violations.
