Avast Pro and Internet Security

Hello,ive been using avast for long now,i always used the free home,but needed something different,and installed the pro trial,but internet connection was stooped,as i uninstalled it,it worked again,

can someone tell me what might be the problem?

I suggest an installation from scratch:

  1. Download the latest version of avast! Uninstall Utility and save it.
  2. Download the latest avast! version and save it.
  3. Uninstall avast from Control Panel (if possible). If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
  4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after you’ve run it.
  5. Install avast! using the setup saved on 2. Boot.
  6. Register your free copy or add the license key for Pro.
  7. Check and post the results. If, for any reason, you did not solve, try doing the step 3 in Safe Mode anyway.

so should i install in safe mode?it didn’t ever happened to me ,my friend installed it on a win xp without any problem,i did installed several sws on my pc even avast s and even the hard ones and had never a problem but this is unbelievable,ill try again and see what happens

Hi i did it ,now internet is ok too,but as i ran the clean utility and told me that avast is uninstalled,when i went to program files i saw avast folder with some application,then removed it manually,restarted and ok,but i had to disable internet and firewall in installation then on again and now is ok

in the http://www.avast.com/en-eu/free-antivirus-download,it shows that the security is more,but do i need all that security as i have and run,

Malware bytes
Free Superantyspiware and
atf?

what is your view?

Thanks

No, I never said that.
Uninstall in Safe Mode if needed.

thanks,now is ok,but what about the pro and the internet security version,which the best?i use my pc like the daily breath

Undoubtedly the best is the Internet Security (antivirus + firewall).
