Hi, Sorry if this has already been covered and I did read the Preliminary questions about NOD32 thread before posting today. Whenever I do a full scan every file has an "... :KAVICHS error opening (Acces Denied) " appendage. Is there a difference between locked files, which I understand from this post, and my "Access Denied" situation? Is there a way for me to "unlock" all of these processes so that Nod can perform a more thorough scan or am I worrying excessively? Btw, I have no partitions and am the only user of this XP machine. Thanks!
