Hello CarlAxel and welcome to the forum.
1. What other security software do you
currently have or did you have
in the past on this machine including:
- Antivirus (AV)
- Firewall (FW)
- Trial versions of AV, FW and other security programs
- Other security software (resident and on-demand)
2. If they were in the past, how did you remove them (the vendor's uninstaller's tool or another way)?
3. What is your OS, RAM, 32 or 64-bit?
I agree with you that running the Avast uninstaller tool was a wise thing to do. Did you end up having to do it in Safe Mode as well? Did you have a previous version of Avast on this machine in the past? If so, did you uninstall the previous version as well and reboot?
Sometimes remnants of previous security software can prevent installation of new security software (like Avast), or there could be other problems. But lets' start with possible remnants since you mentioned you had previous AV's on your machine.
Here is a
list of uninstaller tools for AV's:

http://support.microsoft.com/kb/2435760/Remember to reboot after running an uninstaller. It is also suggested to run a cleaner like
CCleaner after uninstalling, a freeware system optimization, privacy and cleaning tool. There is a
Slim version available as well at
http://www.piriform.com/ccleaner/builds – 4th option down. It removes unused files (cache, temporary Internet files, etc.) from your system, allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. Additionally it contains a fully featured registry cleaner. Thank you.
