While installing the UO client my antivirus detected "regsvr.exe". Googling it revealed this page, among others: http://www.file.net/process/regsvr.exe.html What's up? Have you guys been hacked or something? Is this a false positive?
Regsrv32.exe is the registry service used by windows. This file exists in your windows installation and is not part of the Ultima Online installation. During the installation however the installer makes a few changes to your registry in order to allow the razor program to operate correctly. This is not a virus, just your AV program notifying you that your computer is being modified. Regsrv.exe could either be from an older version of windows, or an unrelated infection that was already on the computer. It is possible however that your computer is already infected and installing the UO Client caused it to access an infected file. The UO:Renaissance installer has not been modified since 2013 and can not contain any virus like activities. I would recommend doing a full scan of your computer with a program like Malwarebytes.
This is definitely a virus, according to everything I've seen. Regsrv32.exe is indeed legitimate, but Regsvr.exe is not. I have since tested by running the installer on a clean system (just installed Windows 7 using the official OEM CD I bought from Fry's Electronics) and the same alert appears. The antivirus neutralized the issue, so my machine is not infected, but I would implore you to take a close look at this, if possible.
regsbr32.exe is not a virus, its actions can appear to be a virus. It is used to register certain ActiveX and DLLs, these actions can trip some antivirus scanners as it is a common method of sneaking in virus' as well.
