My dad bought 3 pc licence for avast internet security and ran into some troubles after upgrading our free versions we had running.
First my main pc with w7 ultimate 64b stopped having internet, after going trough loads of posts on the forum (uninstalled the internet security and reinstalled the free version to be able to).
I ended up using the removal tool and save mode and removed all avast stuff and used removal tool for ad-aware and then ran cccleaner rebooted again and installed internet security
and everything is working fine now.
Then i went to my dads xp sp3 machine did exactly the same thing, but you guessed it, no internet. Not even when turning of all shields and the firewall...
The only way i found to have internet working with avast internet security installed is by not installing the firewall, wich seems well uhhh not what i want
Tried all the ways i could find on the forum, like the uninstaller tool and the use fast checksum checkbox, cleaning the registry with cccleaner.
Atm i have internet security installed without the firewall (tho avast ui still sees it, prob becaus i used the system restore point i made before adding the firewall module).
Obviously avast can't activate it caus it's not actually there, but that's not the issue at hand anyway.
Also tried both the dutch and the english version.
Any suggestions for making the firewall work ?
The win xp professional dutch version with fully updated sp3 had no other virus scanners or firewalls installed then ad-aware prior to upgrading free avast to internet security
btw. i had this whole story written out (maybe even more properly, but i am bad at those verifications and lost my whole story and had to type it again, tad anoying
