This is a bug I reported with the RC1 version of 2.7. I have just installed the final version 2.7.16 and the bug still exists. --- Previous bug report --- I have noticed a reproducable bug in NOD 32 RC1 (and Beta version) on both Windows Vista RC2 and now in the RTM version as well. Both in clean install and upgrades. Uninstall NOD32 and the error stops. It causes an Data Execution Prevention (DEP) Exception with the Microsoft RSS Feeds syncronization process. To reproduce: 1) Install Vista RTM 2) Install NOD32 3) Subscribe to a number of RSS feeds 4) Set the Feeds Settings (Content tab) update option to automatically check feeds every 30 minutes. 5) Wait - at some point, the DEP exception will occur.
