From Pattern File 2.594.00 may cause high CPU utilization
Due to an isolated anomaly in the engineering, development and pattern release process, the UltraProtect decompression may, in certain circumstances, cause some systems to experience high CPU power consumption. This can lead to system instability when this specific file type is scanned using Pattern File 2.594.00.
Anyone know what certain circumstances? I first saw this on Incidents.org and checked my pattern file, I was running the affected pattern file with no problems. The real problem I had was updating to the new file ( would not connect to the server for a while .) ( XP2pro, SP2 )
