I have been away for a couple of days so I could not respond. Although I don't know why, the issue appears to have been resolved in the interim. I started using mainframe computers in 1966 and as soon as desktop kits were available continued on from there. Over the years, I have had numerous occasions to consult help desks, user forums and other support sources and I must say that the responses I received from you guys have been the best I can remember. You understood the problem I presented and provided relevant answers promptly and accurately. Thank you. I am an unofficial neighborhood pc guru and since many of the calls I respond to concern some type of malware, I always try to convince my "clients" that system protection is best if it is automatic, effective, unobtrusive and easy to install. I always recommend that they use a combination of Microsoft Security Essentials (Defender) and MWB paid version. Thanks again.
