Agree with the above. You're getting a lot of suggestions and may be overwhelmed. To make it simple:
1.
Uninstall Ad-aware via the vendor's uninstaller tool and
reboot.
2.
Uninstall Spyboot and
reboot:
- Uninstall Spybot S&D w/Teatimer:

- How to disable Spybot-S&D (temporarily).
http://www.safer-networking.org/en/howto/disable.html . Even though it says temporarily, the resident parts of SpyBot Search & Destroy must be enabled manually if disabled in this manner. TeaTimer doesn't load into memory at all when disabled.
3. Run
CCleaner for both cleaning and registry cleaning. Make a back up of registry fix in Documents or USB temporarily.
4. Download and install
MBAM (Malwarebytes).
5.
Uninstall and do a clean install of Avast (see steps 1 - 9 below):
1. Save a copy of
Avast 6.0.1000 and save it to your HDD if you haven't already:
Free:
http://files.avast.com/files/avast6final/setup_av_free.exe2. Download the Avast Uninstall Utility
http://files.avast.com/files/eng/aswclear6.exe and save it to your HDD (it has uninstall tools for all Avast versions and products).
3. Disconnect from the Internet at this time.
4. Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
5. If Step 4 fails, boot into
Safe Mode (hit F8 repeatedly) and run the Avast Uninstall Tool. If you had previous versions of Avast on this machine, uninstall all versions of Avast at this time.
6.
Reboot. Run CCleaner after reboot.
7. Install the newest version of Avast and
reboot.
8. Get Internet access and register your copy for Free:

Reboot your machine again and when all is working properly, download a defrag tool. There are several good ones out there; one was mentioned as well as free Puran
defrag, which has a boot-time defrag as well as a regular defrag
