I have had a problem in the past of Kaspersky suddenly blocking a lot of links and downloads of malware applications through Opera.
These problems have not happened in a while, as I blocked all my extensions, only re-activating those I truly need.
And the problem went away(I also foolishly wiped my cache/history and lost a lot of data I did not back up, in an attempt to solve this problem as has been stated elsewhere).
Anyway this morning I needed an email translated and fed up with going to google to manually do it, I re-enabled the translator extension. A few hours later now, the malware is attempting to load itself on my computer, and Kaspersky is stopping it once again. I have seen other complaints about this extension in this forum.
I really think Opera needs to look into this extension. The malware does not load straight away, they are very clever and it is only after a few hours.
Anyway it is all I wanted to say, Opera you know about the problem now, I just wanted to warn the other users and dont really want to get into a discussion about this issue.
Ban it or do not; I do not care either way, but if you do use this extension, then be warned, your computer will be hacked.
The extension is the one with icon : the blue background "a" in white on the top left, and the "h" squiggle in green on the right.
