The school i go to has a small computer lab, and it seems like all the computers there, as well as the ones at the reception desk and the office, have some sort of a browser hijack bug on them. I've cleared them all of spyware and viruses, but when i open a browser (any browser) and do a google search for example, and click on a link, half the time im taken not to the website in the link, but to some adware site and spam. And every link opens in a new tab for some reason, and this is annoying as well. Any ideas?
