when i try to run msn messenger(signing in i mean), it grabs 100% cpu. it signs in after a long time(say 2-5 mins), then when i right click the icon in the taskbar, it automatically signs out. this happens about 2-3 times after which all returns to normal(well atleast normal compared to what takes palce normally). also the cpu stays at 100% for about 5-15 mins afterwards. i would like to know if i must scan my computer for malware, sypware, etc using some specific programme. also this doesnt happen if i run messenger from another account(ie another windows user account)
