I have recently installes Kaspersky 7.0 and it deleted trojan and adware.but i am unable to do a full scan it just stays at 1% even after an hour or so.also when i go on the internet a few messages came up saying something was trying to pass on data etc but i blocked that.is it meant to slow my compiter down???and how can i do the full system scan what is causing it to be so slow???thank you
