i have many friends who use daemon tools and DTlite as their primary iso mounting and image burning program. i urge them all to stop immediately. and ESPECIALLY don't update to the newest release. daemontools installer now includes a multitude of toolbar, spyware, and adware installs, only 1 of the installs can be opted out of, the rest are forced.
i repeat, if you install the newest version of Daemon Tools, YOU WILL GET A VIRUS.
this is a disgusting betrayal on the part of the DT brand. they have opted to get paid by sponsors by loading their malware and toolbars instead of continuing the service they have offered users for years.
i removed it from my system with a system restore (back 2 checkpoints, first checkpoint was a fake, being created just after the adware was installed to fool users) as soon as i saw what it was trying to do to my browser, so i don't know all of the symptoms. forum posts suggest the worst of the packs installed is the "sweetpacks" toolbar and adware pack. it will behave like the old Alureon rootkits, changing your homepage, redirecting search results, etc. your browser may look like you got a new bing toolbar, and your homepage has changed to bing search.
