Vista all of a sudden acting weird.... Hijackthis log included

Hello.....

I've been having a few problems with computer lately - I'm not sure what info you need so here we go....

Computer Info:
1 1/2 years old
XPS 410, Intel Core 2 Duo Processor E6420 (2.13GHZ,1066FSB) with 4MB cache
4GB DDR2 SDRAM at 667MHz
320GB Serial ATA 2 Hard Drive (7200RPM)
Microsoft Windows Vista Ultimate 32-bit Edition English

Problems I've been having:

1. Outlook 2003 stops responding in the middle of downloading email
2. Homesite V5.5 freezes when I go from Edit to Browse - this has just started to happen - it has been working fine for over 1 year
3. most programs are responding more slow than usual
4. The other day I got a message that wanted me to back up my file encryption key?! I have no idea what this is about??

I have Nod32 antivirus and did a scan and there are no viruses ....

I just downloaded and did a HijackThis Log - I have no idea what this log means but here it is:
