After doing some research with F-Secure Client Security v9.0, which I believe uses the same anti-virus engine as F-Secure Internet Security 2011, the culprit of the "corrupt file" seems to be the DeepGuard setting "Use Advanced Process Monitoring". If this setting is unchecked, AnyDVD downloads and installs just fine, if it is checked, AnyDVD downloads, but after installation, you get the "file corrupted" message when AnyDVD tries to initialize itself. I believe DeepGuard is just another advanced heuristic program that the anti-virus uses. Other anti-virus programs that are generating a similar error message should have a similar program/setting which can be raised or lowered in intensity.
Once the problem has occurred you have to do the following, since simply turning the "Use Advanced Process Monitoring" won't resolve it (NOTE: This "fix" method was done using F-Secure Client Security v9.0, with other anti-virus programs, it may be different as to what and where the similar settings are located/changed):
(01) Delete the AnyDVD setup program that you originally downloaded (SetupAnyDVD6700.exe)
(02) Select the DeepGuard section and uncheck "Use Advanced Process Monitoring".
(03) VERY IMPORTANT Look for the setting "When a harmful program is found:" and select this setting from the drop down menu: "Always ask me"
(04) Click on the link "Open list of monitored programs"
(05) A box will appear containing a list of all of the programs that are being monitored. There should be four AnyDVD programs that you need to remove from that list:
1 = AnyDVD Application - anydvdtray.exe
2 = AnyDVD Application - anydvd.exe
3 = SetupAnyDVD6700.exe
4 = setregacl.exe
(05) Once the programs are removed from the monitored list, exit that box.
(06) Close everything up and re-download the setup program "SetupAnyDVD6700.exe" once again.
(07) Run "SetupAnyDVD6700.exe" and allow to install.
(0 After you close up the setup program and AnyDVD initializes you will get a warning box asking you if you "trust" this application or not, click on "Allow".
(09) AnyDVD should run with no problems now.
I believe setting the "heuristic" scanning method to a very high/aggressive state in any anti-virus program is simply going to cause too many false positives, as in this case. I would suggest that everyone set their heuristic settings to a "normal" state (usually the default setting), and see if that helps. Unfortunately, with any of the aforementioned anti-virus programs in this thread, once the damage is done, you have to go back and remove the blocked programs from the list and then start all over again.
I hope this helps.
