I am a "newbie" here; so, take it easy please! A few weeks ago I started to be plagued with a couple of Dynamic Link Library error messages on certain websites that I frequently visit; mainly, out of town newspaper sites. One referred to "urlmon.dll" and the other referred to "mshtml.dll." These error messages stated that Internet Explorer (currently IE8) needed to be shut down which was done. I use a Dell Dimension 8400 and still have XP Home Edition as my OS. Since I still have a paid basic coverage plan with Dell, I went to them first with this problem. All I got with that department of Dell was that there was nothing wrong with the hardware on my system and it was suggested that I go to their Software Errors Dept. This I did and after agreeing to a WHOPPING FEE to work on the problem (after a considerable amount of time), I finally got to the point that they said that they had found a virus (unnamed by Dell when asked which one) which they claimed was removed and said that I had to reformat. Well, to say the least, this isn't the first time I have reformated and reluctantly, I did so thinking that my problem with dll's was over. No such luck! A couple of days later the same darn dll error messages started to reappear. I currently use Norton's 360 and back up my files through their online backup service. After reinstalling my backed up files, these pesky dll messages started to reappear. What I am wondering is "did the virus (if I have one) get backed up with my files and if so, I must have put it back in to my PC's OS?" After looking at the attached configuration of my PC, hopefully one of you will be able to come up with an idea as to what's going on and how to correct it. Of course, if it's not a virus, I will be going back to Dell to ask for a refund.
