During one of many downloads from the web, the appearance of mozilla/firefox was changed.
The new opening page did not resemble firefox in any way. I lost the firefox toolbar. There was no access
to the "help" or "tools" tabs on the firefox opening page. I downloaded chrome, and checked internet explorer, both of which started with a normal home page. I went to the control panel and tried the "add/remove" feature which works for managing most applications. What it did with firefox was provide a link to support.mozilla.org which had no help for this virus. My current version of SpyBot search and destroy seems not detect or eliminate this virus.
