is a php virus without wmap or xampp can be executed on windows system ? and if no, can norton will be detected that virus if it is not working.
If you think you have this malware, I would suggest that you run a full system scan with your Norton product. If that doesn't fix it, then I would suggest you visit one of the free malware removal sites, register with them to see if you have any malware. If you do have malware they will help you to clean it up and perhaps find the source of the malware. Going to one of these sites will give you peace of mind if nothing else.
Please see this link for an up to date description of these sites plus the addition of a newly listed site formed by one of our successful malware remover users who unfortunately has passed away. That site is still being run by a good expert who happens to be one of the other Gurus. The new site is listed first in this link.https://community.norton.com/en/forums/malware-removal-forum-recommendations
