Thanks. I first installed MS .NET Framework v4.0 (18Mar2010) under WinXP SP3. Then I installed OK Panda Dome v21.01.00 under WinXP. I selected "Offline installation" during installation. I have not yet activated the program because activation requires entering an email address. After the first run the Settings window indicates "Last updated 12/26/2025".
First the good news: Panda Dome v21.01.00 runs OK under WinXP on my old Inspiron 7500 (700 MHz Pentium III, SSE-only). The program does not seem have a conflict with other programs installed. Kerio Personal Firewall v2.1.5 has no issues with the program. It is even possible to run My Ancient version of Kaspersky simultaneously with Panda Dome, no conflict.
Now the bad news: I made a virus-check with Panda Dome v21.01.00 of "My personal in the Wild", which is a collection of 100 infected files downloaded with eMule. I had prepared this collection a year and a half ago for testing-purposes by taking at random 100 files from a HDD full of infected downloads from eMule. Panda Dome v21.01.00 flagged only 6/100 files [msg: 8,531 scanned, 7 detected, i.e. 1 file was flagged twice, because of multiple infections], Only 6 files were quarantined, and 94 infected files were left as "clean" in the folder \My personal in the Wild_6Jul2024\
For comparison: When I ran My ancient version of Kaspersky with this test set of 100 infected eMule files, Kaspersky scanned 171,873 files contained in the various .rar, .zip, .exe etc in \My personal in the Wild_6Jul2024\ and, detected 167 viruses, trojans etc. 99 files were cleaned, the single file which was flagged but not cleaned was a .rar file containing in turn infected multi-part .rar files.
Panda Dome v21.01.00 does NOT install under Windows Server 2003 SP2. When I tried to install it under Win2003 SP2 I got the incorrect error message: "You must upgrade your version of .NET Framework". Panda Security apparently did not prepare a recent corporate edition for Windows Server, maybe no demand. Kerio Firewall flags a file named "TUNNEL.EXE", which has to be given permissions. Which IT-Manager would be inclined to license software which opens a tunnel into corporate computers? BTW, Panda Security is a Spanish company https://en.wikipedia.org/wiki/Panda_Security which was acquired in March-June 2020 by the U.S. company WatchGuard https://en.wikipedia.org/wiki/WatchGuard
BTW, Kerio Personal Firewall v2.1.5 (30Apr2003) does not have a Server version either, but is still my favorite firewall under WinXP.
