Re: Malware injection cleanup advice

[Georgi Kodinov]

I am not aware of malware or viruses that attack ibdata files. So its either a case of dumb mallware trying that on the wrong kind of file and just garbling it in the worst case or it's a false positive from your anti malware tools.
I suggest you either restore from your backups if you have them or try a mysqldump on the affected databases and then inspect the resulting sql for weirdness.
