Thanks for the easy to follow guide with links. I found 3 trojan viruses on two computers and they are now resolved. After using the tools, Windows would not load on the most infected computer and the Startup Repair could not fix it. I used the Bootrec.exe tool to rebuild the BCD – there is an article in Microsoft support that is easy to follow. I am not IT savvy and was surprised when I was able to resolve this so quickly and efficiently. Norton did not find any of the trojans, but someone on a forum told me that is probably what was causing the issues I was having. May the Universe bless all of you who are so helpful and make things easy to understand.
