I did not ask Tony to run all of that at once.
Sure the pc is memory starved, however, if he just uses it
for email and visiting eham, etc it is up to the task.
Now if he wants to watch Youtube videos or try to
run a video editing program, then that is a no go.
Even one or two malware items on the machine will slow it down.
Every machine and user is different, I've run an older
IBM thinkpad with 256mb real memory for years and
use Firefox just fine. I use it when I travel to remote to
the office machines, email and eham.
It also worked well for digipan psk31 on field day.
The bloated MS code is no secret along with memory leaks
and patches upon patches.
If a newer machine is in his budget, take a look at
IBM certified used, all about three years young, off lease
and with free shipping and includes Windows 7 OS.http://www-304.ibm.com/shop/americas/content/home/store_IBMPublicUSA/en_US/icpepcs.html
Honestly James on 256 meg it is a moot point to do all of this. The extra effort could even force old HD into failure. It needs more memory, not more scanning or checking. Code has gotten so fat it is in a constant state of swapping just to run before you add more tasks too it. it would crawl with these scans constantly swapping code to do it.
