ComboFix is a very powerful reporting and scripting tool that was developped by sUBs, used by members of the malware removal team here on BleepingComputer (and also on other forums). This tool can easily break a Windows installation if poorly and/or wrongly used. It can make the whole system unbootable and also delete everything present on your drives (leaving you with close to no chance of recovery) or damage your Windows installation so badly that you would be forced to reinstall it. Therefore, you should not
be using ComboFix unless you are in one of the two situation listed below:
- You have been trained in an online malware removal forum to use ComboFix;
- You are using it under the supervision and instructions of a trained malware removal professional on BleepingComputer or another recognized malware removal forum (UNITE forums for example);
If you already ran ComboFix on your system and need assistance with the log, you will have to post a thread in the Virus, Trojan, Spyware, and Malware Removal Logs
section of BleepingComputer, where a trained helper will assist you.
