我部電腦中左毒, 入到windows 但之後click 唔到任何野

我部腦中左毒, 今日開機, 佢話我中左毒,(trojan horse, dldr.conhook.gen係c://windows/tutusp.dll) then 彈左個野出黎叫我choose 點做, 我chose 左delete 佢, 之後部機就clik唔到任何野la....
之後我再開過部機, 佢都係彈個野出黎話我中毒, 我都係chose左delete 佢, then 都係唔郁........
之後, 我再開, 佢彈左: d 毒係c:/windows/system32/tmpc4/tmp.dll, 但之後都係click 唔到
最後個次, 佢話d 毒係c://windows/tutusp.dll, 話可以lock 左佢, then 我click "yes" 再開機, 佢彈: " 入c://windows/tutups.dll" 時發生錯誤, 找不到指定的模組" ..........都係click 唔到野
