then hit your delete key on your keyboard. Yes to confirm. Keep doing that until you see Finished searching the registry. If anything adverse happens start your computer in safe mode then double click the back.reg file. Then reboot.

Did you see anything listed in add/remove programs titled "AT&T software" or "SBC Yahoo"? If so, it's probably somewhere under that. From what I read about it, it sounds like it's built into a specialize browser too, so you may need to uninstall it from the browser add-on/plugins or completely uninstall the browser, if the browser has it built in and it's not removable (specialized browser). You may want to download another browser before doing that (like firefox)

Many times programs will have an uninstall option installed as a program link that you can access from the Start menu. For example you would click "Start" menu --> Programs --> AT&T programs (or whatever it's called) --> Yahoo Online Protection 1.0 --> Uninstall. The "-->" indicates a new fly-out/sub-menu window.

Check to see if there are any processes/services for that program are actually running (press ctrl alt del keys at the same time, to get into task manager). It may not actually be installed anymore, and your new AV program may just be seeing some orphaned file that is still being executed at startup. If that's the case, you can fix it by using Autoruns for windows.

I know Autoruns works for Windows ME & XP, read the documentation or forums if you have a newer OS.

Keep in mind that your getting this error message, because you should only have ONE anti virus program installed (kinda like the "Highlander") in an OS at any given instance. Otherwise, they tend to fight with each other, causing major problems.... Same thing goes for software firewalls.

I did find a solution online called Yaxclean, which also will work if you ran the uninstall and it failed/hanged during the uninstall procedure... I haven't tried it myself, so use at your own risk.

A program I use that works much better than windows add/remove is Ccleaner. This program has an option to add/remove programs, and works better than the standard option in control panel. You should be able to uninstall this program with ccleaner.

If your having problems with viruses, or suspect you have a virus (the main reason most people change anti-virus programs), you might try using the kaspersky rescue disk located here.
Because the kaspersky rescue disk does an "offline" scan, you don't need to remove your current anti virus, and it is much more effective at catching root-kit viruses. However, because it does install/write a significant amount of information to your hard drive, I would caution you to run a check disk (chkdsk) prior to installing, especially if you've had the computer freeze and had to hard boot or manually shut off the computer, or had a recent power outage. Just right click on your C drive in file explorer, click properties, and select the "tools" tab and select Error Checking. Select "Automatically fix file system errors", DO NOT select "scan and attempt to recovery of bad sectors" (will take forever). When trying to run it, windows will say it can't do it because other process are running, but it will offer to run it during the boot phase next time you reboot (select that option, then reboot your computer). You'll have to burn the ISO file you download to a CD, and then setup your computer BIOS to boot from that CD/DVD drive when you boot (typically called "boot sequence" in Bios setup).

Whew, kind of a rant there. Hope all this helps.
