alpha antivirus

alpha antivirus is on my computer and has blocked my access to the internet.
I am a computer virgin and havent got a clue what to do.
Is it best to take it in to someone to repair and pay what ever it takes or have I a chance to be able to get rid of this myself at a small cost (mentally and financially).
Ive been trying for the last 7 hours and am just getting in more of a mess.
PLEASE HELP
Thanking you in davance Karen :

After the download:

• Close any open browsers.
  
• Very Important: Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results". Please visit here if you don't know how.

Troubleshooting ComboFix

Safe Mode:

If you still cannot get ComboFix to run, try booting into Safe Mode, and run it there.

(To boot into Safe Mode, tap F8 after BIOS, and just before the Windows
logo appears. A list of options will appear, select "Safe Mode.")

Re-downloading:

If this doesn't work either, try the same method (above method), but try to download it again, except name
ComboFix.exe to iexplore.exe, explorer.exe, or winlogon.exe.

Malware is known for blocking all "user" processes, except for its whitelist of system important processes such as iexplore.exe, explorer.exe, winlogon.exe.
