We run a Java application at work and starting today (Jan 16), version 3 (build 621) of NOD32 has slowed the launch of any parts of the interface to a crawl. Current def. version is 2798. At first I thought it could be related to the latest Java JRE 6 Update 4 so I rolled back to Java 6 Update 3. No difference. Advanced heuristics and Run-time packers are off in real-time (but on for new or modified files.) The only way things are normal is with real-time protection totally off. **EDIT** Did a bit more checking. If I leave real-time protection on but uncheck the "Scan on File open" option, Java runs normally.
