Regarding my thread from yesterday on my system problems, I was finally able to get virus software to run and found a virus previously discussed on Elite from that ebook back in March. Now I have removed the infected files but apparently the EMM486.exe file was part of my registry. NOw my lack of knowledge of windows comes back in to play. My machine seems to be working fine again but when I boot I get this "cannot find emm486.exe file invalid path" type of message, and also a message to edit my registry if this file is no longer used etc. I attached the exact messages as a screen cap. But when I look in windows help it essentially says DON"T F&%K WITH YOUR REGISTRY! Should I attempt to delete this emm486.exe file from my registry or simply deal with the annoyance of these messages -which I have to click OK about 5 times it seems-every time I boot? Thanks for any help/suggestions. Finally, I am still not sure it was this virus that caused the problem as I had noted that my (new) printer all of a sudden was giving me whacked out error messages too, so I uninstalled it. THus I don't know if it was a hardware problem wioth this printer or the virus. From reading the other thread it seems as thought his worm virus did not really cause system issues, it was more of a securtity problem.
