A: 4K â also known as UHD (more on this in the next answer!) â is a picture technology that quadruples the number of pixels found in a full HD picture. These pixels are usually arranged in a 3,840 x 2,160 configuration, compared with the 1920x1080 you get in a full HD TV.
Files with the .7z extension are very similar to Zip files. These files are compressed archive files, usually created by the 7-Zip file archive utility. 7Z files can make it easier to send files and folders over email and the Web.
There is a chance that your 7z.exe error could be related to a malware infection on your PC. These malicious intruders can damage, corrupt, or even delete EXE-related files. Furthermore, there's a possibility that the 7z.exe error you are experiencing is related to a component of the malicious program itself.
