Operationally to use MB while surfing should not be a problem. However, isn't it a little counter productive to do so as we know that MB does not scan in real time? My thought is the potential is present to have a 'new" bug without warning or detection embed itself in an area of the H/D after it has already been scanned. The critter would not be detected until the next scan and thus in truth a user would not know for 100% certainty that the drive was clean. DA

> Why does a computer work in the morning but not later in the day? It is a machine from a more responsible manufacturer. Therefore it provides, for free, software to determine where the problem lies. Execute this comprehensive hardware diagnostic from the disk drive, from a provided CD, or by downloading that software from the Dell web site. Boot it from the hard drive, CD-Rom, or a flash (USB) drive. It executes without needing Windows or other complications. It will test all hardware with or without malware infections. It will tell you one important fact. Is the hardware good or bad? Is the problem in hardware or software? All computers have a line between hardware and software. Diagnostics will quickly identify which side of the line has a problem. In your case, the problem is probably on the software side. However this software, only provided by better manufacturers, makes identifying problems faster and easier. Removes all doubt. Everyone should execute their comprehensive hardware diagnostic once when the machine is still good to know what it does. Most do not even know that software exists. Important is to first identify hardware integrity before moving on to software problems. Malware can be first removed by the Microsoft Malicious Software Removal tool. Downloaded from their web site. Latest version is probably 14 Feb 2012. This will remove the simplest problems. Enough to get most machines functional enough to do other solutions. The program even can be loaded on a CD or flash drive to be executed from there. It does not remove all malware. But it is an easiest solution to implement on the worst infected machine. Your mal-ware software (McAfee, Norton, Trend Micro, etc) then can execute to remove more comprehensive infections.

Thought I'd update. Got Windows installed without a hitch, Dell talked me through it. I debated whether to put Win 7 in since I was starting from scratch but worried some of my software might not work Everything went well except I couldn't find drivers for some things such as my wireless adapter so couldn't get on line. Called Linksys and they spent over an hour trying to get the driver in and finally did. That was the best part, finally getting on line and getting hit with a zillion MS updates. I have misplaced or lost some software. We moved here in March and I could not locate my Office disk, wireless mouse/keyboard software and a few other things, might have gotten lost in the move. I'm most concerned about Office 07. I paid for it. Dell says they can't help and I could try contacting MS and see if they would do anything. I haven't moved any of my files back yet. Otherwise, I feel like the computer runs better than when it was new. Things seem different, have to fool with fonts and views, but I'm amazed how effortlessly the machine runs. This computer always seemed to have a few 'glitches' but I was used to it. Now it seems so fast and smooth (of course there isn't much running on it yet.) I don't know how to thank everyone for all the support and help I received. You are the best friends anyone could ever ask for. I guess you can teach an old dog new tricks! Thanks from the bottom of my heart... Jane

I booted up this morning and there they were, all five of the removable drives. What knows? There's a lot of computer-wise folks here at the KT so I don't usually ask at the computer forum. The folks are great there but kinda slow with the replies. LOL Thanks! Lori
