UR V2 is incompatible with F-Prot antivirus.

I was not able to reproduce this behavior on a Windows 2000 SP4 test box with the eval version of FProt (labeled as v3.16f on their web site; I accepted all installation defaults) and UR 2.0. We'll need more info to investigate further, including:
1) The version and SP of Windows you're running

1) Windows XP for Tablet PC 2005. Fully patched.

2) Computer hardware description (CPU, RAM, free disk space, etc.)

2) Fujitsu P1510D convertible notebook. 1.2Gh proc, 512MB RAM, 60GB disk 70% free not fragmented

3) The version of FProt you're running

3) v3.16f

4) FProt configuration settings and/or files

4) Default F-Prot config.

It's possible that the problem will only occur if UR runs at startup. To test that, boot to safe mode and use RegEdit to delete the registry value "HKEY_CURRENT_USER\Software\Microsoft\Windows\Curr entVersion\Run\Ultra Recall", then restart Windows and start UR after startup is complete.

I have already tried to boot without UR running. It still hangs at login. (This make me suspicious of a different root cause).

It's more likely a problem with FProt than UR itself (perhaps it has trouble processing files that UR installs), since anti-virus software hooks into Windows at a low level, while UR runs as a regular application. You might submit the issue to the vendor of FProt and see if they will investigate or provide suggestions.

I have submitted the issue to F-Prot. I have had no response from them at all. I am now looking for another vendor.

It's interesting that the lockup occurs even after UR was uninstalled. The UR installer copies files only to the install path and removes them during uninstall (I suppose Fprot may have copied these files elsewhere for its purposes or something). The only registry entry UR creates that would affect the system in any way is the entry mentioned above, which simply causes UR to be started at login, and that also gets removed during uninstallation.

I think I may have the root cause but it needs testing. Some time ago, I encrypted the My Documents, Application Data and Local Files folders and all subfolders and files recursively using the inbuilt encryption that came with the OS. I think this may be a factor because I just logged in as Administrator, not in safe mode, and everything runs fine. This tells me the problem is associated with my user profile. My working hypothesis is that F-Prot combined with encryption is the issue.

I’ll decrypt all files, uninstall both F-Prot and UR then reinstall both.
