I purchased Avast! Security Suite the other day and am in the process of installing it on my systems. On my 32 bit Vista system, everything went fine. However, when I installed it onto my brothers 64 bit Vista system, the firewall would not activate. Everything else is functional in Avast including the updates feature, but the firewall is not running and the buttons do not activate it.
The specs on the system are:
OS: Vista Premium 64 bit (Service pack 2 and all updates installed)
6 GB of DDR2 memory
750 GB HDD
AMD Phenom Quad (2.2 GHz)
Nvidia GTS 250 graphics card
OCZ 600 watt power supply
Asus TV tuner
Virus definitions: 100206-2
I have done some basic troubleshooting already, including using the avast removal tool followed by a registry and temp file cleaning before reinstallation. I have also checked windows firewall which is still functional and have tried to turn on AVAST firewall with windows firewall on and off. I read somewhere that Avast firewall requires windows firewall to function, but so far it has not made a difference on this problem. I have run Hijack this on the computer and sent the log file to Avast, but I am trying to get the firewall up and going ASAP. An interesting note: I did a comparison between the services running on my system and the ones on my brothers. My system shows the firewall service listed, his does not (under msconfig). However, his does list the firewall under device manager when you "show all hidden devices". It is really confusing. The only thing I can figure is it is a 64 bit incompatibility, but I read that Avast 5.0 is compatible with all Vista and 7 versions. There are no other security suites except for malware bytes and spybot s&d, but they are both the free versions so no active monitoring so there should be no conflict. Anyways, Sorry for the long post, and I hope that someone can help with this. Thanks all for your time!!
Oh, one more thing: Has anyone had any issue with DPC cpu usage staying about 10-15 percent after hibernation with Avast installed? Never had this issue before this software. (I Have tried troubleshooting all hardware and drivers, no luck) Thanks again!!
