A. BackWeb is a generic downloading tool used by various software companies that incorporate it into their product to download data such as product updates. BackWeb can collect information from your PC and deliver it to the collection site. When you connect to the Internet, BackWeb also connects to retrieve advertisements that are then displayed on your browser as popups. I'm sure you know by now that this is not something you want on the PC.
Here's how to get rid of it: Try uninstalling it using the Add/Remove Programs in Control Panel. If there does not appear to be an uninstall program, go to C:\program files\BackWeb\ and remove this directory. Run MSCONFIG (Start, Run, type MSCONFIG), check the Startup tab and disable anything related to BackWeb. Look for any .EXE file starting with BackWeb and delete it.
Finally, download one of the spyware detectors (I like Spybot), install it, check for and install any recent updates, then run it and have it fix the found problems.
Guus.
