I read this Prevx section of Wilders for information. I never have major problems with Prevx with SafeOnline. The minor problems are quickly solve at online support. I wonder if some of the problems may be traced to improper installation procedure. When I install any program I backup registry with ERUNT I clean away the junk files clean registry, modestly defrag, run chkdsk I backup registry with ERUNT exit from all non essential processes the last I use System explorer so that only necessary system processes run. I use the program through its paces to check for problems I seldom have problems.
