I'm using dial up and that's slow enough to begin with, but the malware/addware
or whatever it's really called slows things to the extreme. I've got Spybot and
run that now and then, but it doesn't seem to matter because those programs get
back in pretty quickly and some of them it seems as soon as I log on. Is there a
way to keep them out altogether that won't slow the computer way down? I've
gotten the impression that some defense programs slow things down more than the
viruses do...
Dialup networking, at 5KB/sec, gives enough bandwidth for
discretionary surfing. With some care in what sites
you select for viewing, you can do a few things.
(Like, my weather site, can give a weather forecast,
without needing a lot of downloading.)
But when it comes to maintaining an OS, the overhead level
is really too much for dialup. If Adobe Flash, or some
other program, is always phoning home and checking for updates
at startup, that can slow things down a lot. Or Windows Update,
if you have that set to automatic. If you're using an AV program,
the definition updates for that can be overwhelming at times.
The sum total is, it's pretty hard to check the weather,
when the computer is "making a meal for itself" all the time.
You need an OS which is doing less stuff on its own,
to feel more in control. And to be able to check
the weather again. And that's not the design trend.
Even with Linux, there are a few things they do after bootup,
that might make use of a dialup connection, so you might
not even have peace and quiet with one of those OSes installed.

There's a lot that could be done to your installation,
to make things better. I'm not competent to do all of it,
or explain it all. And there are some things you can do,
which will "fix it", but you won't like the side effects.
For example, on an older OS, Windows "SteadyState" is a way
of locking down the OS, so fewer things can take over. A
similar concept, is the way the OS is set up on the machines
at the public library or an Internet Cafe, where the user's
environment is refreshed on each reboot. The problem there,
is you don't get to keep your user files.

Using AV tools, is a "next best" alternative. The tradeoff there,
on a low performance computer, is having all the CPU cycles
sucked up by the software. Some of the sluggish feeling can
be removed, by using an SSD in place of a hard drive (so
the accessing of files is less noticeable). But the AV tool
is going to want daily updates, and when that download happens,
you're going to need to "walk away" from the dialup computer.

Doing a "clean install", might give momentary relief from
your current symptoms. Followed by reinstalling your AV
program. But that's a pretty extreme solution to the problem.
Running malwarebytes.org MBAM might help, but then, we
don't really know exactly how messed up your system is.
(There is a free version.)
