Bellevue-based 180solutions said this week that it has tracked down "Sniper84," a hacker who enabled the company's advertising software to be automatically installed on users' computers.

Late last year, 180solutions required all of its software distribution partners to use an updated version that is supposed to prevent unauthorized installations. The company said it contacted everyone who received software from "Sniper84" and gave them the opportunity to uninstall the program.

As if that wasn't bad enough for the company, a spyware expert is claiming that 180solutions is ignoring deceptive software installation methods used by its partners, according to eWeek.com.

The company told eWeek it is working to address those problems.
