I updated it and it's still causing me troubles.
Which program do you recomend me to test if there are any malwares?
(Except Malwarebyte's Anti-Malware, because since its new version, it deleted some important dlls and system files)

I've been experiencing the same thing. At first, when I have opened Opera, the first five minutes were just crashing if I would try to load pages. Now, things are getting worse.
My Flash Player version is 16.0.0.287, PPAPI, but I had to deactivate it. And I thought at first it was the Stash, but Stash takes just some time to load, no problems.

I remember before the last updates, it wasn't that bad (maybe one or other time)
Sorry for reviving this post...

Another question: I have QuickTime and other plugins as NPAPI, does it make any problem??
