good internet security for PC and laptop ....

Without a protective and anti-virus program you should not use a PC or laptop anymore. Every day there are attacks from the network that increase.
Just a week ago I received allegedly by a specialist from the Amazon MarketPlace by email an invoice. However, I am equally stumbled upon it because I had not ordered anything and the mail looked different as otherwise the mail from Amazon and their dealers. And I should to look at my bill click on a link. Otherwise, the bills are inserted as picture or attached as a .pdf. Of course I do not made. Even if you want to know as the first pulse to who exactly for what want from a money.
Who knows what would have happened. At best, nothing or my antivirus program would come forward and blocked the attack or the malicious file deleted immediately.
I was lucky so far. But we had already hosts of relatives and friends here who were affected. That was enough of a virus in the BIOS of the numbers-you-100Euro mesh during PC boot up to the renaming of all photo and music files (which were so broken and beyond repair).

Enclosed in the narrow package is a CD and printed is the necessary subscription key.
If you chose a different antivirus program already on his computer you have to uninstall this before completely. We had already F-Secure in 2014 it and uninstall it.
If one the CD starts automatically. For safety, you can now do on the CD a security scan. But does not have one.
Is it with his computer online, the program automatically connects and downloads the latest version now practically in 4 steps as depicted in the package.
The Key must be at the beginning of Setup and enter addresses as a subscription. A mail address or password, such as McAfee do not need.
Everything is in German and the download is quite fast as the installation. With us as 10/15 minutes.

The new version, like its predecessor (used a year and never had anything) very good brakes neither the system or interfere programs at startup or application. We have running under Win8.1.
The user interface is simple and self-explanatory. You can use the program in the basic setting or make even more settings (Tools).
There is next to the Web Protection for browsing on secure pages are various other options such as safe search results, secure online banking, parental control. Updates makes the program automatically in the background do not notice you.

Conclusion: Very good and effective protection for devices with which you are traveling a lot on the Internet. Quick and easy to install and easy to use. Nevertheless the desktop computer is still running as usual good and fast. Never again without ...
