New Tricks from Browser Hijackers?

Fortunato_NC asks: "I'm the IT manager for a small business that delivers its service via a browser-based application, and we take around two dozen to three dozen tech support calls from users each day. Many have something to do with pop-up ads making using our product nearly impossible, which is odd, since we don't have any advertising on our website. Of course, it's spyware causing the pop-ups, and we recommend using a product like Ad-aware to take care of the issue. However, not everyone gets the message. Today I was on a client's computer using WebEx helping them remove yet another 'browser helper'. The uninstaller for this program consisted of running no fewer than four separate programs, each of which forced closed the Internet Explorer windows, killing the WebEx session, and making it very difficult to service an already upset client ('What do you mean I have to join the meeting AGAIN?'). It seems as if this product anticipated the need to have someone remotely help the user remove it and went out of its way to make that task nearly impossible. Has anyone else on Slashdott encountered spyware or malware specifically designed to make life miserable for *remote* support techs? What other nasty tactics are spyware authors using that you've noticed?"
