Avast Premiere

I’ve bought an avast premiere and when i tried to download and install it, it wasn’t possible. Can you help me?

Elietecandido welcome to Avast! Forums.

A little more info would be nice. Like:
¿ what does it say when the download/install can not be done ?
¿ What Windows are you running; XP, Vista, Win7, 8 ?
¿ Another security program actively running; AV, AS, FW ?

How to install Avast! cleanly:

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 aswclear.exe

3.) Download and save a fresh copy of Avast!. Be sure to have your lincense handy if running a paid version.

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 aswclear.exe in safe mode for any Avast! you may have had before,e.g. v.6 o v.7, and then for v. 8. Reboot into normal mode after uninstall.

NOTE: aswclear has the ability to make your system go into Safe Mode. Just run it in normal mode and 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.

My windows is 7, and I had Avast! 7.0 running, but it’s not running anymore. When I click on this link http://files.avast.com/iavs5x/avast_premier_antivirus_setup.exe (given in my inbox from Avast), it doesn’t redirect to the download, adn when I go to Home i the site of Avast and click on “Download”, anything happens. Help me, please.

Since it is the same link I gave you, and it is working fine for me, I suppose something else may be happening in your system even malware related.

Follow this guide: http://forum.avast.com/index.php?topic=53253.0

and attach ( Do not copy/paste ) logs for AdwCleaner, malwarebytes’, OTL, and aswMBR.exe.

An specialist will be notified after you attach the logs.

To attach logs click attachments and other options. See image.

BTW are you the administrator or have administrative rights over that computer ?
