Q: I'm getting eval matches on files I know are ok. How can I suppress these?
A: In the file admin/syscheck.php, look for the array $eval_ok_files. You can follow the pattern and add to this list as appropriate for the mods you have installed.

Q: I was hacked, and I deleted all the files SysCheck reported. Am I ok now?
A: NO! SysCheck is just a starting point. You need to follow all the recommendations in my blog post Recovering from a hack. In particular, you need to reload from a known good backup. If you don't and another file was tampered with (for instance, spammy links were added to your footer, or the credit card details are being recorded), you will never know it. You must restore from a known good backup.
