hello im a bit of a novice here can anyone explain very simply how to solve this when starting up windows i get file not found - c\ windows\ system32\ aqepct \services\ exe not found then if i close this it says application not found - same file name. i end up closing this four times in total. i have had troajn horse but removed it using avg antivirus - but i dont think its all gone as pop ups occur on internet use. i removed pe devicefile also. i also get error message saying ipwins.dll file not found. i rang computer shop -they suggest reinstalling windows xp but i dont want to do this as it means losing stored games etc or having to save programs on flash drive then reinstalling which im not sure how this works. please help.
