should I delete these entries made by malware "ghost.blueecho88.com" from information_schema under php my admin??

[Niji]

I found this infection in information_schema under php my admin

1 match in PROCESSLIST with the following paragraph entry
SELECT * FROM `information_schema`.`PROCESSLIST` WHERE (CONVERT(`ID` USING utf8) LIKE '%ghost.blueecho88.com%' OR CONVERT(`USER` USING utf8) LIKE '%ghost.blueecho88.com%' OR CONVERT(`HOST` USING utf8) LIKE '%ghost.blueecho88.com%' OR CONVERT(`DB` USING utf8) LIKE '%ghost.blueecho88.com%' OR CONVERT(`COMMAND` USING utf8) LIKE '%ghost.blueecho88.com%' OR CONVERT(`TIME` USING utf8) LIKE '%ghost.blueecho88.com%' OR CONVERT(`STATE` USING utf8) LIKE '%ghost.blueecho88.com%' OR CONVERT(`INFO` USING utf8) LIKE '%ghost.blueecho88.com%' OR CONVERT(`TIME_MS` USING utf8) LIKE '%ghost.blueecho88.com%' OR CONVERT(`STAGE` USING utf8) LIKE '%ghost.blueecho88.com%' OR CONVERT(`MAX_STAGE` USING

How do I delete all these entries, I mean all above lines ????

When I try to delete by just clicking on Delete, I got the following error

#1044 - Access denied for user 'u652934113_kqCk7'@'127.0.0.1' to database 'information_schema'
