Help! Please! I can´t remove BV:KillFiles-[K] with AVAST 4.7 Home edition!

What I make to remove it without format my computer?

If a virus is replicant (coming and coming again), you could follow the general cleaning procedure:

  1. Disable System Restore on Windows ME or Windows XP. System Restore cannot be disabled on Windows 9x and it’s not available in Windows 2k. After boot you can enable System Restore again after step 3.

  2. Clean your temporary files. You can use CleanUp or the Windows Advanced Care features for that.

  3. Schedule a boot time scanning with avast. Start avast! > Right click the skin > Schedule a boot-time scanning. Select for scanning archives. Boot. Other option is scanning in SafeMode (repeatedly press F8 while booting).

  4. It will be good if you download, install, update and run AVG Antispyware. Some users recommend SUPERantispyware, Spyware Terminator and/or a-squared (take care about false positives).
    If any infection is detected, better and safer is send the file to Quarantine than to simple delete than.

  5. If you still detecting any strange behavior or even you’re sure you’re not clean, maybe it will be good to test your machine with anti-rootkit applications. I suggest AVG, Panda and/or F-Secure BlackLight.

  6. Also, if you still detecting strange behaviors or you want to be sure you’re clean, maybe making a HijackThis log to post here and, specially, scan and submit to on-line analysis the RunScanner log would help to identify the problem and the solution.

  7. After you’re clean, use the immunization of SpywareBlaster or, which is better, the Windows Advanced Care features of spyware/adware cleaning and removal.

  8. Finally, when you’re clean, check for insecure applications with Secunia Software Inspector to update insecure applications and avoid reinfection.

Yes I am… but this is an English-only forum. Ask in Portuguese what you don’t understand only, not any question.

All good, I go to try to understand here and in case that I have problem I ask! Excuse me for bother and for horrible english!

This virus shows in autoexec.bat, and is don’t detected in boot scan!

Ai cara, vou escrever em Português para que vc entenda e juro que é a ultima vez que encho o saco!! Fiz os passos que vc falou, disabilitei a Restauração do sistema, apaguei os arquivos temporários e baixei o AVG antispayware. Passei ele e ele achou 36 spans que o AVAST não havia pego anteriormente nem no but, porém nenhum deles tinha o nome BV:KillFiles-[K]!!! Passei o avast no boot depois disso e não deu nada!! reiniciei e nem o AVG nem o AVAST acharam mais o BV:KillFiles-[K] no autoexec.bat!!! Isso significa que ele foi eliminado ou pode ser que não???

Don’t worry. There isn’t an international standard for virus names. Sometimes, one application names a virus different that the other. Also, remember, avast is an antivirus and not a software is perfect. AVGas is a very good antispyware.

I’m not sure you’re clean. You should run SUPERantispyware, Spyware Terminator and/or a-squared and follow the step 6 I’ve posted before.

Thank you very much!! I go finish all steps to your list, but i find that’s all right!!
