The HP software on people’s Macs didn’t change but the chain of trust that vouched for it was broken, so it began to trigger alerts as if it was malware. In the HP incident, HP revoked the certificate it used to sign a lot of its printer software. An organization proves its ownership of that secret key using a digital certificate, and that certificate’s authenticity is vouched for by a certificate authority (CA).

In simple terms, code signing relies on a chain of trust: Signing is performed using a secret key. (For a primer in code signatures and certificates, see our previous coverage of the HP incident.) If they’re not, they can’t be considered 100% safe. Code signing is a really important security feature, and all apps really ought to be signed. If an app is signed by the company that created it then you can be sure you’re using an unadulterated version of the software. What is code signing, you ask? In short, it’s a cryptographic way to validate that an app has not been tampered with. What’s causing the warnings?Īs was the case with a similar issue affecting HP printers last year, it’s all about code signing. (It’s almost like Citrix is trying to make its apps sound shady!) Other companies are also seeing an impact to older apps, such as An圜onnect’s vpnagentd. Among them are two other Citrix apps, ServiceRecords and AuthManager_Mac. Unfortunately, the name “ReceiverHelper” fits right in. All of these adware names are pretty generic, revealing nothing about what they’re actually supposed to be doing.

There has been a fair bit of Mac adware going around lately with odd two-word names, like StandardBoost or ActivityInput. Not only is macOS apparently saying that it is, but the name is highly suspicious. Of course, if you thought that this was malware, we’d have to forgive you. Only some older versions of the software are causing problems. Not all Citrix software is being flagged as malicious, fortunately. It is a component of Citrix, which is legitimate software made by the company of the same name. Under settings check “Override high DPI scaling behavior” and select Scaling performed by: System.If you’re one of the affected folks, the good news is that this isn’t malicious at all. Update: In the recent Win 10 build the Compatibility tab is changed a little. Perform the same steps for the wfica32.exe in the same folder.Goto the Compatibility tab and disable or override (depending on your Windows 10 build) the DPI scaling.Right click the CDViewer.exe and choose Properties.Open the Explorer and navigate to C:\Program Files (x86)\Citrix\ICA Client.To change this behavior for Citrix Receiver we need to open the properties of the executables, the CDviewer.exe (found in C:\Program Files (x86)\Citrix\ICA Client) Fixing Citrix Receiver blurry text on Windows 10 The affected files for Citrix Receiver are the CDviewer.exe and wfica32.exe. So to fix the problem, we need to turn it off for Citrix Receiver. In Windows 10, the DPI scaling is turned on default. This problem occurs due dynamic display scaling on non DPI aware (older) programs ( more about that here).

On Windows 10 your Citrix Receiver may show blurry text.
