Well, then Avast website must be wrong as it categorically mentions of two different versions "*Both the 32 and 64 versions..." (see the red thick arrow in the image). Here it is attached once again.
In response to Eddy's reply "there is no 64-version" (see Eddy on: Yesterday at 08:32:16 PM), I attached a screenshot from Avast website (see mbr on: Yesterday at 08:50:08 PM).
Eddy did not respond to that attachment. Instead, DavidR attempted to explain the issue differently without commenting on my attachment reproduced from Avast Website.
The contradiction was between Eddy's categorical statement (which was in variation with Avast Website declaration) and DavidR's reply (which was differently presented).
While Eddy maintained that there was no 64-version, DavidR attempted to clarify that single version comprises both and does its job depending on the installed version of the operating system on PC.
You would realize that two are different: Eddy's no and David's comprises both. One is negative and the other is affirmative. And, that is where contradiction takes place.
Finally, is it correct to state "there is nothing to rectify"? (see Eddy on: Yesterday at 08:32:16 PM).
Yes, the statement at Avast website (image reproduced) needs to be rectified so that it does not remain misleading.
