hpztsb05.exe and ~e5d141.tmp look suspect, although the former might be
printer related only. The second picture has a few troubling files such as:

ctagent.dll
nem219.dll
~e5*.*
alchem, epuf and a2install, etc...

I suggest rebooting and rechecking your speed. Check again tomorrow and
(tomorrow + 1): if you have the same problem, go through a virus and spy
scan or alternately, fdisk / format / re-install everything. A fresh format can
be great for a machine once in a while :-)
