Hey guys I just had exponential trouble to login on my one of my windows 7 accounts. After finding that disconnecting my computer from the internet was the only way to sign in (yes I ran both malwarebytes and Avast in safe mode to no avail with full scans). I now believe I may have been hacked. So what's the next step from here? Backup what I can and reformat my drive? Or can I not even trust whether all my files are corrupt and have to reformat without backing up files? Or is there anyway around having to completely reformat my computer?
