Avast version 8.0.1455

[CraigB]

Whatever problem you are receiving isn't going to differ by using the Pro version and threatening to use a cracked license isn't going to help your cause either as avast automatically detects cracked licenses and then you'll be in even more of a pickle.

I'd suggest you follow the instructions placed out for you by Gopher John.

I guess English is your first language(it is not mine) and you saw all posts.I don't understand your
post.How can I be unprotected with Trial reset?Tested by many and working.
All I want is Avast Free I used for years and this new practice by Avast is shameful.
I don't need answers from members of Avast cult but from persons responsible for
this debacle.

If you are using ANY cracked software, your machine is likely infected.  It could be interfering with your attempts to install a proper version of Avast.

My machine is not infected.Proper version of avast free was installed.Avast forced Pro version
upon me and changed my Avast Free to Pro Trial.Post from Indian didn't help.I never had any
problem with previous versions.This version 8 debacle is horrible.Please read all previous posts before
posting new ones.

Run the uninstaller for any AV's you used prior to avast from here to remove remanents: http://singularlabs.com/uninstallers/security-software/
1. Download avast! Free Antivirus: http://forum.avast.com/index.php?topic=117113.0
2. Follow instructions: http://www.avast.com/uninstall-utility (Run this tool for all prior installed avast! versions..!!)
3. Reinstall avast! with the downloaded installer from point 1.
4. Reboot

Avast must NOT force you to install pro version this time and it has never done that see to it while you register the free version you only go with the free option and you need to read carefully sometimes

IOBits can and has caused problems before with Avast installs.

Since English is not your first language, you may use other Avast forums located at http://forum.avast.com/index.php?board=21.0 if you find one that you understand better.  The instructions you have received have worked well for others to resolve the same issue you are having.  Of course, one has to fully understand and follow the instructions.  There must be no other antivirus program installed on the machine or it will definitely cause problems.  Disabling the other antivirus is not enough.

I have iObit Uninstaller (portable).MBAM on demand,Windows Defender on demand,Trojan Remover on demand,
SpywareBlaster,ABP in all browsers,AdFender for IE10.My Windows 7 SP1 was installed 2 months ago.Only antivirus
with real time protection was Avast.First it was version 7 updated to 8 something and then to version 8.0.1483
and all of this started.There were 2 clean installs of latest version.Last week I also updated SafeIP free if that
matters.

BTW I don't have any problems with how Avast is working.It is working great and it is very
light on my system.Only issues are with Software updater doesn't recognizing Firefox 19.0.2
and saying that latest version for IE10 is IE9.

Remove all traces of IOBit, and disable Windows Defender http://windows.microsoft.com/en-us/windows-vista/turn-windows-defender-on-or-off.  I've disabled Windows Defender and haven't missed it at all.

I use MBAM on demand, SpywareBlaster, and ABP in Firefox without any issues.  They are well behaved.  I have no experience with the others, but I would think that AdFender wouldn't be a problem.

Same issue here with Firefox 19.0.2.  I haven't yet updated to IE10.  Supposedly, it will be among the WindowsUpdate offerings tomorrow for Win7.
