fast and reliable 1

I installed in the meantime, the update to 5 PCs and notebooks, the installation went smoothly.
For me, none of the installations could not get, as mentioned here in some reviews.
The installation on 3 devices, which had a different virus protection previously went without a problem.

I went on all devices as follows:
- Download KIS 2015 from Kaspersky server
- Internet connection is disconnected (pulled network cable to the PC, wireless disabled on laptop)
- Old anti-virus software be uninstalled (KIS 2013 / KIS 2014 + third-party), maintaining registration information at KIS, because of the ongoing license period.
- Restarts
- KIS 2015 installed with the download,
- Registration code as a reserve registration code added thereto.

I could on any PC or laptop find that the speed is slower than in 2013 or KIS KIS 2014. Other Anri-virus software slowed the PC / notebook sometimes very, so this was also replaced by KIS.

The devices were both my private PC + laptop with and the first devices of my employer, the next 6 notebooks are supplied next week with updates. If there are problems of any notebook I will report it here.

Addendum 14.09.2014:
In the meantime I have KIS 2015 installed on more than 10 PCs, regardless of their virus protection was previously available - the installation went smoothly. None of the PCs remained the install depend.
Previously (in contrast to other manufacturers of anti-virus software) nor recognized any important software as "potentially dangerous". That I had not have a hoax - not even with various industry software (electricians, doctors, etc.).

Addendum 12.23.2014: previously negative attention to me only the "Secure Payment" I could not turn it off in Firefox, even if it was turned off at KIS itself. Problem was with me - I could not perform more Paypal. Only the deletion of the plug-ins in the Registry disabled secure payments. Thus, the 5th star is just something in danger, if I find even more things that review is completed
