I installed Avast 4 and the problem is solved.
The support for Avast 4.0 will stop shortly, therefore you need to have Avast 5.0 in your machine or you will not get the virus definitions updated and be protected.
Since this was a conflict with the other software and Avast, you need to do a clean uninstall and install of Avast, but you now have an old version of Avast on your machine.
Please do the following:
Uninstall Avast and do a
CLEAN install:
1. Save a copy of newest version of Avast (5.0.864) for the product you need and save it to your HDD:
Free –
http://files.avast.com/iavs5x/setup_av_free.exe2. Download the Avast Uninstall Utility, aswClear5.exe
http://www.avast.com/uninstall-utility and save it to your HDD (it has uninstall tools for both 4.0 and 5.0).
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.
You will need to uninstall Avast 4.0 and 5.0 and 5.1 at this time.6.
Reboot.
7. Install the newest version of Avast and
reboot.
8. Get Internet access and register your copy for Free.

I also suggest if you do not have this software on your machine already to download it to clean your machine. Install it now and clean your machine prior to performing the above instructions, then do it again afterwards.
CCleaner, 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 (but make a backup in My Documents just in case).
Let me know how this works for you. Thank you.
