Running a windows 7 OS -- with both Superantispyware and MS security essentials -- on a newly created user profile -- every so often a firefox screen pops up with pointing to tubestv.com which shows porn. I don't have firefox installed on the laptop and this website just pops up unexpectadly and with kids this has me concerned. Both the MS and Superantispyware do not fire off and nothing shows up when I do full scans? Trying to figure out how this is happening and what is triggering it to pop up bypassing MS and Superantispyware Pro - not cool when its the girlfriend it seems to happen too and not my profile! Any ideas or ways to stop this?
