I would like to support the company by buying the professional version, but I just can't see the value it adds.
Firstly, your kind comments have supported Avast already!
There are a few extra features, but the primary functions are the same as the free version.
For most users, the Home version is fine. Some advanced users like the "bells and whistles" of the Pro version, but both Home and PRO offer excellent protection.
How about adding some real compelling feature to the pro version? Maybe an anonymizer or firewall
Anonymizer or Accelerators are freely available from either your ISP or on the net. This "feature" deviates from the main purpose of Avast.....protection from virus infection. I have also suggested that a "firewall" be incorportated into Avast or packaged with one. No feedback yet from the Avast Team. However, any such undertaking would take away from the work presently being done on Avast. It is better to have ONE GREAT PRODUCT, then two that are ok. Know what I am getting at?
.......so it makes it worthwhile to buy the yearly subscription and get rid of some other security software we have running.
It IS worthwhile to buy the yearly subscription now! AND it just makes sense considering the protection and features of the Avast Pro version. Whether using Home or PRO... removing some of the "other" security software makes sense. Keep in mind that another AV that does not run resident is a good idea as a backup and check to Avast results.
Hope the information helps.
