I am using magento 1.7 version for my store. Its worked fine . But from last 2 months its detected malware in site. When ever i browse any link open 4 popup with junk site. I have externally scanned my site via Foreginx , and they detect malware in my site www.coralconcept.in . I replaced current file system with previous file system which were working fine , but still i face the same scenario. I am attaching the report with this mail. Foreginx suggest me to upgrade the magento version. Will this fix this issue? If so then how can i update my site magento version without negative impact?
I can not figure out the actual effected files . I never include direct JS / JQUERY files link in magento files. Foreginx also detect malware like onepage checkout , customer accout etc. pages . Please help me out from this very uncomfortable condition ASAP.
Please see the attached scan report & suggest me what to do.
