Slim, clear, high-performance - 100% protection but has no virus scanner in the world

A good deal for a virus protection for two years for three devices, especially as far as that is fast today.
A Windows Phone, a Androidtablet, a desktop PC (Windows or Mac) has already put together this.

F-Secure is now an old hand in the anti-virus / internet security.
Time slipping into the midfield, but usually at the front while testing.
The best protection worldwide, as printed on the cardboard box, but may like to be scrutinized.

The "100% safe" but is not a happy wording.
100% secure, not to catch a bit, if you click without necessary precautions to everything that moves.
There can be no matter how great antivirus.
A virus protection is at best a seat belt, a bumper.
The prevents mild cases worse, but not a total loss when driving fully against the wall.
This is driving so and while surfing the Internet otherwise.

Must be scrutinized and the cardboard box itself.
It contains only the code for the security package and the Password Safe or links for downloads.
Practical, fast and resource-efficient would be shipping by mail.

The download and installation is then quite simple.
After a short registration with an email address and an indication of the coupon codes to get to the download page.
The download / installation time after the package is pleasing slim.
After an initial scan and update itself shows the very clear basic menu.
The main functions are directly on the three tabs (Status, Tools, Statistics) callable.

The scan engine is very performant. The time of a full scan is significantly lower than McAfee, Symantec and BitDefender.
Even on a notebook the burden of the Online Scan is only slightly noticeable,
the boot time has lengthened by more than 10 seconds.
F-Secure has integrated a more resource efficient game mode - can be selected directly by right-clicking the task icon.
So far, but it was necessary in any game with me.
Even otherwise, I still have not noticed any appreciable side effects,
not on Steam, the virus scanners in yes is very sensitive, Windows 8.1 itself not less.

Conclusion. Must intervene until a compelling offer, a virus scanner that watches silently in the background.
To poach a charter with naive carelessness in the shallows of the Internet, but it is not absolute.
