still shows I have home version,

I installed the home version and then i decided i wanted the pro version, i downloaded it but it still shows I have home version, should I have uni-stalled before the pro version?

Depends on the license key.
So you want to take this path: REGISTERED Home → TRIAL Pro?

Thanks for the reply, I have already put the REGISTERED key in for the home version, I liked it so good I thought I would go with the pro version,

Just not sure if I need to unistall the home version?

No need to uninstall the home version, just buy the license for the pro version and put in the key. Avast will update itself to the pro version.

Thanks for the info, before I received your advice i unistalled the home version and installed the pro, it worked great! I love it, I just heard McAfee upgraded to a 10.0.21 today and is now compatible with the 64 bit windows, well I am hooked now with Avast, so has anyone had Mcafee and switched to Avast?

Take a good look in here:

It turns out the Czech company Alwil Software offers a 64-bit version of its Avast 4 antivirus software. Even better: It's a free download for home users. I haven't tried it yet, but the readers who suggested it to me seem to like it.

I asked Alwil Program Manager Ondrej Vlcek to elaborate on his company’s free product, and the fact that Avast has gone to 64-bit before anybody else. He explains: “Porting a system tool to Windows x64 mainly means porting its kernel-mode components (i.e. device drivers). This is because legacy 32-bit device drivers don’t run on this new platform. The engine itself can be 32-bit, and actually is better to be 32-bit as 99.9 percent of today’s malware is still 32-bit (i.e. not 64-bit) and that’s what we’re trying to cover. That doesn’t mean we don’t detect 64-bit malware, though. It’s just that there’s no point of creating a plain 64-bit AV solution (with no 32-bit parts) yet.”

So… enough said I believe… ;D

Cheers !
