After I instaled Avastefree I lost the acess to the comentaries in the Blabbermouth and Whiplash sites. I tried in other computer that don’t have Avastfree and works fine. How do I fix this problem?
Thanks in advance for your help 
what AV did you use before installing avast?
did you uninstall it before installing avast?
did you uninstall according to vendors instructions/removal tool ? http://www.avast.com/en-eu/faq.php?article=AVKB11#artTitle
Yeah I had AVGfree and Uninstaled it before I instaled Avast.
Thanks for the link. Gonna try the AVG removal and see what happens
Gustavo I can go to both sites. No problems whatsoever.
I tried the AVG removal and it worked and for a while I could access the comentaries section on those sites but now happened again.
Although I uninstalled AVG and used the AVG removal, I searched for AVG in my system and this what appears.
I’m thinking uninstall Avast and Installing it again. What do you think?
Are you sure you used the right version for the AVG you got ?

Clean your temps, most of those files are temps.
Install from scratch:
1.) Very important to remove all remains of other AVs installed before Avast. Use this site to execute uninstall utilities for other AVs.

2.) Download and save to your desktop avastclear.exe
3.) Download and save a fresh copy of Avast!.

4.) Open Avast! > Settings > Troubleshooting > Uncheck " Enable Avast! self-defense module ".
5.) Uninstall Avast! normally through Control Panel > Programs & feature ( Vista, W7 ) or Add and remove programs ( XP ). Reboot. If you can not complete this step, continue with step # 6
6.) Even if you were able to uninstall Avast! in step # 5, it is important to run avastclear.exe in Safe Mode
How to use avastclear: http://www.avast.com/en-us/faq.php?article=AVKB10#idt_02
NOTE: When executing avastclear, it will ask to be run in safe Mode so follow instructions.
7.) Reinstall fresh copy of Avast! and reboot.
Be aware. Avast! will offer Chrome during installment. Remember to opt-out if you do not want it.
