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.
Restart PC / laptop -
- 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 anti-virus software slowed the PC / notebook sometimes very, so this was also replaced by KIS.
A scan of an entire PC with "Normal" HDD takes time, but you can continue working alongside. This makes other software different - here the scan (half-time) is faster for the utilization is so high that you can not go alongside meaningful on PC.
The devices were both my private PC + laptop with and the equipment of my employer, here, there has been at any notebook or PC problems.
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, medical practitioners, etc.).
Advantage: to get even 2 years license, so you do not have every year to think of the initial purchase. (This I have in use)
Addendum: negative attention so far is 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
