I wanted to get your opinions on this problem I had.
A couple of weeks ago, I scanned my computer with AVG free edition and got a notification that there was a rootkit, it was an inline hook rootkit that I could not remove using AVG. I then ran MBAM, but it did not detect anything. Panicked, I did a system restore to an earlier date when I did not have the rootkit. The only thing I installed that week was Windward through Steam and did some light internet browsing (must have gotten it through this). Anyway, doing the system restore made it so AVG did not detect the rootkit anymore. But I did not trust this and performed a clean install of Windows 10 on my computer. I reformatted and cleaned both drives I have with the Windows 10 recovery disk, just in case, and the install worked fine.
Currently, I am afraid to use my computer as I do not trust it anymore. I installed Avast over AVG this time and reinstalled MBAM. I also got MBAR just in case and have scanned my computer religiously and nothing comes up, but I still don't trust the scans! Honestly, I need some clarification to put my mind at ease.
1. What type of rookit was this? Ring 0, 1, 2, or 3? I wish I had not been so rash to system restore and documented what the line said instead. You may not be able to answer this unfortunately. I remember it said inline hook - %unknown%, or something close to that.
2. What programs can I run to be absolutely sure that this rootkit did not hop over during the clean install?
3. I have heard that some rootkits can infect firmware, should I get a new hard drive? I really don't want to...
Looking back, I wish I would've come here for help right away, but I heard clean installing the OS would get rid of pretty much all viruses, malware, and rootkits.
I appreciate all feedback/suggestions! Thank you!
