I’m not sure what to to tell you regarding the licenses. I know the protocol with Professional licenses are different (and a bit more stricter) than with the Home version licenses. If you don’t get a further response here, I would recommend going to the avast contact page…
and writing an e-mail to the address for general inquiries.
As to your last question, you should download an additional program that deals specifically with adware and spyware. I would recommend SpywareBlaster to start. If you want a free solution, there is Adaware and Spybot SD. There are quite a few commercial applications (ones you pay for) available also. However, you will need to be careful what you choose! Many “antispyware” applications are what is termed “rogue” software. There is more information here…
Maybe we can help with your first two questions as we use this licence.
Yes there are 10 and they can be used on any 10 PCs. Interestingly all the ten PCs use the same licence key. Now the thing that we are not sure of is if you can switch between PCs (manking any total of 10). We wonder this because each time you install and put in the Licence Key, it is then checked online. This makes us wonder if once it has received 10 registrations of that key then any new registrations would be blocked. As we use this package with just 5 PCs then we don’t have this problem at the moment.
Also you can install on each PC without the use of WHF. Worked for us anyway.
