Good Internet protection, but with errors

I had previously had been listed Norton Internet Security, have me then but very over their pricing annoyed (much cheaper than buying a new contract extension, 3 PC license, there was no more). Therefore, I switched to Kaspersky. The installation went smoothly, and it was weird already, that was reinstalled after installing a large download, one more update with a large download.
Overall, Kaspersky makes a good impression and is almost not felt in daily use. I particularly like the "Safe Browser", the similar special protection for online banking Services offers.
And now we come to the first mistake: The safe browser launched my online banking site to a proxy Kaspersky own, and showed me that one can not trust this Kaspersky page. This is actually a no-go! Especially when it comes to safe services, they must also function safely. You can correct this error, in which the Kaspersky certificate is installed manually in the browser. To this end, there are instructions on the Internet. However, such a thing even a potential point of attack for hackers. The not so great and so should not be!
Then the next problem: When viewing PDF documents always disappeared the window frame from the Adobe Reader. I would not have dreamed that this could be due to Kaspersky, but it was true. Here you will find instructions on the Internet, saying that it was necessary to install a newer version. This does not happen automatically. Well, not so great, but it also works.
Now I hope that the Security Kaspersky actually works with high quality. Well, the question is how you can check the Sciherheit remains. Ultimately you will probably have to trust that it works well. I just hope that Kaspersky gets its quality problems under control and the next versions are better.
