There are two things that usually cause these errors.The first is from Windows system files that Windows doesn't let any programs access. This is a Windows security feature. As long as the scan continues, these errors can be ignored. You can check the cause of the error by going to the 'Log' section of Vexira.The other cause are Windows help files (.chm files) that sometimes generate a lot of errors in Vexira. This is rare and doesn't cause any problems. Errors on .chm files can be ignored.Article ID: 48, Created On: 10/7/2009, Modified: 6/29/2011
