I just finished to run my NOD32 from BartPE for first time. Accordantly to descriptions in previous threads. Great facility! No need to generate any plug-in. I enjoy to have purchased NOD32 license for two next years, after having used it since March 2006. However I got some warnings. INo idea what these practically mean. If causal while running from BartPE or not.
