PC protection and precaution: These safety instructions should be observed at the moment

Depending on the threat on the web, you should take particular care and take specific measures to protect yourself against fraud, pests, hackers and more. On this page, we will give you tips and recommendations on the security messages of the last few weeks.


Software Warnings: Beware with these tools


As a general overview, we recommend our report: "IT Security Trends 2017: New Dangers and How to Protect Yourself."


Cautions against current threats: How to protect yourself


The Flash Player is regularly negatively affected by critical security gaps. We recommend disabling the browser plug-in and enabling it only on secure web pages that the plug-in really needs. Alternatively, a Flashblock add-on helps for the browser. If you do not need Flash, you should completely uninstall it. Almost all major websites have now replaced HTML elements with older HTML elements.


Due to known vulnerabilities, we recommend installing the updated version 16.00 of 7-Zip (here for download).


Apple has set the support for the Windows version of QuickTime - despite open security gaps. We therefore strongly advise you to uninstall it.


The threat of Ransomware on the web is currently high. In addition to known blackmail Trojan such as Locky, Petya or Jigsaw, new trojans can be added at any time. We therefore advise you to be more careful with e-mail attachments - even if they come from supposedly known senders. You should also keep your AntiVirus software up-to-date.

The world's largest social network also attracts criminals. Over the past few months, there have been repeated warnings of fraud. Frequently, fake Facebook profiles will foster the trust of users. As the mash runs, check out our guidebook "Facebook fraud with fake profiles - how to protect yourself and your contacts."


Like Facebook, Whatsapp is also used by criminals. The fraudsters promise about false vouchers, lure with free smileys or claim that the Whatsapp subscription would have expired. This is usually the intention to access the dubious websites of the victims' personal data. Encounter any news from unknown numbers or pop-ups on your smartphone with increased distrust.
