Granny's back...anyone care to tell me what this means? [View All]

Just did an update for Spybot S&D, and then immunized.
On that page in this version I now have (1.5.0) a big old list of goodies appears and within the list I am now told that I have 578 unprotected items.

Reads like this:
Software Cookies
IE(32 Bit) Software Domains) 147

Software cookies 2
IE 32/64 Bit) Default (Domains) 117
Owner (den) Cookies 1
Owner (den)Domains)132
Global Hosts 147

Total 578 unprotected items.
I have tried to find out what this means by way of the help section and am striking out.
Teatimer is on.

Windows XP2
IE6
HP 526X Cable connection
Plenty of memory.

All up to date.

Used CCleaner this AM

As per usual, don't know what I'm doing but this thing is so slow, I check and do scans daily just to make sure nothing has latched on to my machine. I don't even know what else to do and have no $$ to call in the Computer docs at $125.00 just to walk in the door.
