Thanks raven. I looked at the first link you provided and I don't see anything that resembles what I had. So I still have a question. As I recall what popped up on my screen was something that looked like it came from Microsoft, said the computer was infected with a virus, and warned not to shut the computer off. It told me I should click to start the antivirus program. The first time it happened--when I fell for it--I assumed that it would run Windows Defender. My question is, then, does Microsoft ever do this? That is, if indeed I get a virus in the midst of searching the web, is there ever a legitimate Microsoft warning that pops up telling you not to shut the computer down and to click to run a scan? If not, then there's no problem with trying to find out what's legit and what is not. With whatever I got it was truly hard to tell. Thanks!

Jean I only use MS Essentials on my Win 7 machine. I have been clean since July with the beta version and October with the real stuff. When you get your new computer fired up you will see small icons near the clock. Clicking the up arrow will bring a small pop up where you will see the green bungalow shaped icon for MS Essentials, as long as it is green and has a check mark you are good to go.

Thanks everyone. A mixed bag of feedback, but mostly stick with XP and keep programs updated and run antispyware and antivirus programs. I do those already. I browse on Firefox and Chrome - never IE. Thanks Pipsy for your perspective. I hear it - and will keep it in mind. But given those that feel caution is sufficient for now, and my real constriction to switch systems this spring, I will probably continue with all cautions. Here are some follow up questions from everybody's posts: 1 - Unplugging external drive when not in use. I have a problem because my Synology NAS is always in use - as is one of my two external hard drives. First, I have lots of video stored on both that the family accesses to transfer to our Tivo's to watch on the television. That needs to be plugged in. I also have my desktop and my daughter's Mac esktop set to back up to the NAS weekly. Owbist - can you (or others) tell me what kind of vulnerability I'm exposing myself too? 2 - Can somebody provide a link and explanation of the ESET online scan? That's one new to me. 3 - I tried NoScript on my firefox and disabled it. Azinoh and the XP security article I mention below, both recommended it. But when I tried it, it was really interfering with a lot of things I was doing. That's been awhile so I dont' remember specifics, but it was just a big pain. Can somebody tell me more about the protection it offers - and are there settings to address how often it popped up and interfered with things? 4 - I do keep flash and java updated. I know many disable java, unfortunately one of the streaming stock programs I run depends on it. 5 - For my work laptop running Windows 7, I had a BSOD from conflicts with Avast. It was a known issue and was recommended to use MSE instead. If MSE isn't that good, should I risk trying Avast again? if there was a conflict in August/September, is it likely fixed since then? anybody know about this? 6 - In another post on this topic, somebody recommended this site/information: http://windowssecrets.com/top-story/securing-xp-pcs-after-microsoft-drops-support/ This site is certainily suggesting to stop with XP - but offers some safety measures if you continue. One was setting up IE so that it can't connect to the internet (but will connect to the homenetwork). "Disable Web browsing: After support ends next April, consider reconfiguring Windows XP to block its access to the Internet. (Remember: You’ll no longer need IE or Windows Update for system updates from Microsoft.) To do so, open IE, go to Tools/Internet Options, and then click on Connections. Click the LAN settings button (see Figure 1) and then check the “Use a proxy server …” box (see Figure 2). Next, enter 127.0.0.1 into the Address box. Finally, check the “Bypass proxy server for local addresses” box." Until this week, I had not encountered proxy servers. I stumbled on it bc. in updating my husband's Windows 7 computer, somehow both chrome and FF got reset to use a proxy server and they weren't connecting to the internet. Using Chrome's troubleshooting info, I was able to disable using proxy server. But now that I've seen the setting, I could set up proxy server for just IE. My question is, will this prevent me from accessing the internet using FF and Chrome (I don't think so but want to be sure)? Is there any reason to do this if I'm the only one in the family with an XP computer and I don't go on IE? Lastly, why do I need to keep IE if I'm not getting Windows updates? is it also for other microsoft updates that I could use (like Word)? Thank you. Lynn.

probably when you went to IE8 the Active X features that are normally active in the older versions of IE were all disabled. I agree with zep you can enable the active x for your windows update site. Here is a link that might be useful: active x with windows updates
