We will need more information to be able to help you:
- Which OS are you using? Is it up to date?
- What avast! version number?
- Do you use a firewall? Which one?
- Do you have any other antivirus installed in your system?  Did you have in the past?
- Any other security programs that could interfere?

Hi, I have the same problem. It happened after a virus attack. Since then, whenever I started my computer, the resident protection failed to start up and a message appear on the screen saying the license key is not entered. Im using Window Vista, windows firewall with windows defender. At the same time I have spybot, malwarebytes anti-malware, and spyware blaster. I have been using them together with avast for few months and they all working smooth until now. So help me please. I have uninstall and install avast both in normal and safe mode. What can I do next?

I suggest an installation from the scratch:

1. Uninstall avast from Control Panel first.
2. Boot.
3. Download the latest version of Avast Uninstall and use it for complete uninstallation.
4. Boot.
5. Install again the latest avast! version.
6. Boot.
7. Check and post the results.

To be sure you're clean, I suggest:

1. Clean your temporary files.
2. Schedule a boot time scanning with avast with archive scanning turned on. If avast does not detect it, you can try DrWeb CureIT! instead.
3. Use SUPERantispyware, MBAM or Spyware Terminator to scan for spywares and trojans. If any infection is detected, better and safer is send the file to Quarantine than to simple delete them.
4. Test your machine with anti-rootkit applications. I suggest avast! antirootkit or Trend Micro RootkitBuster.
5. Make a HijackThis log to post here or this analysis site. Or even submit the RunScanner log to to on-line analysis.
6. Disable System Restore and then reenable it again.
7. Immunize your system with SpywareBlaster.
8. Check if you have insecure applications with Secunia Software Inspector.

I would say ensure that all remnants of AVG are gone.

AVG Remover, download tool from here, http://www.grisoft.com/ww.download-tools there is a 32bit and 64 bit windows version (in your case 32bit), ensure you use the correct one.

Check the remains of AVG that David said and check your Standard Shield sensibility to Normal (not High).
Left click the 'a' blue icon, Details button to expand, Standard Shield at left and set the slider to Normal.
