I want to ask if I install DMRs on PCs of some very novice type of PC users who don,t understand anything about PC security, software installation etc, will it cause any loss of functionality for them especially using MS word documernts, IM messengers etc. The reason I am asking it is that, many time I install free AV programs for some people who have no idea at all how to deal with the OS problems and security.They can,t even understand a simple pop up alert of an AV. I usually install Avast for them( install and forget type of application, easy update with dial up), FireFox, Opera and SiteAdvisor, though I see most of them using mainly IE.( Will be adding BOClean for them once it is vailable). I have now started to install DMRs for the three browsers as I think it does not cause any loss of functionality for the browsers( correct me if I am wrong). But still I am not sure about using DMRs for MS office documents( word, power point etc), messenger clients and OutLook express. Will it cause any problems for them? Is it needed at all? What is your opinion? Pls keep in mind that these people are very very primitive PC users. Don,t expect them even to undersand/ answer a simple virus alert from an AV or to regularly update and scan with an on-demand scanner. I want an absolute NO HEADACHE/ IDIOT PROOF type of security for them and I hope all this set up might be good for them.( Virtualization/ sandboxing is not an option here). Thanks for the input.
