Security for computers and digital identity

Anti-Virus, Password Safe

I can no longer recommend the last two commercial products I used and have cancelled my subscriptions (first Trend Micro, then Avast).
I also cannot recommend the annual subscription “Avira Prime” (cancelled).

Anti-Virus for Windows/Mac


Microsoft's Defender is now as good as, or in some cases better than, its external competitors. Therefore, there is no need for an external solution.


Apple protects their computers with several techniques.
No need for an external solution.

Independent Security Experts

I recommend to read the tests of the independent provider for services in the field of IT security and anti-virus research AV‑Test GmbH before renewing your subscription or buying a new one.
And you should also read the tests of the independent provider AV-Comparatives.

Not only the Test Result counts

The test instances mentioned above only check the quality of the software! Other things do not influence the test result.
For me it is not only the test result that counts, but also where the company is located and how it deals with customers (data).
Better read negative reviews from other customers before you sign up for a subscription!

Password Safe for Windows

KeePass Classic Password Safe

KeePass is a free/open-source password manager or safe which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key-disk. So you only have to remember one single master password or insert the key-disk to unlock the whole database. The databases are encrypted using the best and most secure encryption algorithms currently known (AES-256 and Twofish).
Apart from the installable Windows version, there is a portable version that leaves no traces on the host system.

You can use KeePass on your USB stick, iPod, external hard drive or even CD, on any PC and without leaving any personal information behind.
