電腦既作業系統一問

好可能，輪到你個新防毒俾人搞掂咗

你要知道之前個病毒會唔會有「後遺症」；
另外搞得掂個病毒唔一定等於你部機已經乾淨；
可能佢用替身做替死鬼，等你以為你已經清咗佢；
同埋你清理病毒之前，你另外backup開嘅file可能亦已經做咗「帶菌者」，
你倒番D file落部機時就會再中過毒。

唔係冇其他方法，但係你要花時間去check好多野，得不償失，
所以我recommand你將部腦Format重新黎過。

Try on Windows' Safe mode by press F8 when Windows start and do virus clean. If you can't boot into Windows anymore, the easier way is that try to copy all data files by whatever methods(HDD->HDD, external USB HDD box....) and then reinstall the new OS la.

For me, if I can go into Windows again, I will backup all data files and then try to use "msconfig.exe" -> Startup to disable any suspected startup files(trojan/virus).

good luck.
