Hi,
My computer once again is acting like it has a big problem. I have noticed when I start windows, and run just about any programt anytime, the system is slower. Online browsing is delayed, and often has crashes.
I have tried to resolve this problem by using the standard methods of running:
CCleaner
Symnatec Anti-Virus
Ad-Aware
Spybot Search and Destroy
eWido

I have cleaned and quarinteined when possible and yet the system shows minimal improvement.
For some one reason, one virus in Ad-Aware has been moved to ignore.
Further Symnatec shows the same viruses nightly.

I have listed below the latest results from running HiJack This and As-Adware

HiJack This:

Does anybody know
1)Why my CPU is running slow?
2)What I can do to fix?
3)Why Ad-Aware has ignore and what this means/I should do?
4)Why Symnatec shows and what this means/I should do?

Thanks.
I'll take a look at your HJT...Your HJT log is fairly clean.
Couple of entries, you want to "fix":
- O3 - Toolbar: (no name) - {4982D40A-C53B-4615-B15B-B5B5E98D167C} - (no file)
- O9 - Extra button: AOL Toolbar - {4982D40A-C53B-4615-B15B-B5B5E98D167C} - (no file)
- O9 - Extra 'Tools' menuitem: AOL Toolbar - {4982D40A-C53B-4615-B15B-B5B5E98D167C} - (no file)

However those shouldn't affect speed of your computer.

You can start with two things:

1. I've noticed, you have few items, which are not needed as startups. You may uncheck them in msconfig:
- O4 - HKLM\..\Run: [TkBellExe] "C:\Program Files\Common Files\Real\Update_OB\realsched.exe" -osboot
- O4 - HKLM\..\Run: [Adobe Photo Downloader] "C:\Program Files\Adobe\Photoshop Album Starter Edition\3.0\Apps\apdproxy.exe"
- O4 - HKLM\..\Run: [NvCplDaemon] RUNDLL32.EXE C:\WINDOWS\system32\NvCpl.dll,NvStartup (only needed at startup, if you overclock your card)
- O4 - HKLM\..\Run: [SunJavaUpdateSched] "C:\Program Files\Java\jre1.6.0_02\bin\jusched.exe"
- O4 - HKLM\..\Run: [QuickTime Task] "C:\Program Files\QuickTime\QTTask.exe" -atboottime
- O4 - HKLM\..\Run: [iTunesHelper] "C:\Program Files\iTunes\iTunesHelper.exe"
- O4 - HKCU\..\Run: [ctfmon.exe] C:\WINDOWS\system32\ctfmon.exe (if...CTFMon is involved with the language/alternative input services in Office XP)
- O4 - HKCU\..\Run: [updateMgr] "C:\Program Files\Adobe\Acrobat 7.0\Reader\AdobeUpdateManager.exe" AcRdB7_0_8 -reboot 1
- O4 - Global Startup: Adobe Reader Speed Launch.lnk = C:\Program Files\Adobe\Acrobat 7.0\Reader\reader_sl.exe

Disabling those startups, should give your computer some new life.

2. I've also noticed, that you have quiet few services running. Some of them may be unnecessary.
Go Start>Run, type in:
services.msc
and compare your list with BlackViper list:
