Three remarks not directly related to product quality.
The cheapest model is the same as many others at varying prices, up to 69.99.
On the other hand it is, like the other, compatible with Windows XP, which is not mentioned. I had to restart twice its installation. Blocking incomprehensible. Now everything is fine.
Finally, as soon as I received warnings for license renewal my computer started to row and to behave strangely (about 15 days ago) But as soon as the new version was installed he regained excellent responsiveness . I do not believe in coincidences.
Sale at any price, a true philosophy.
Hop!
