This is a new, Lenovo G50 with windows 8. The owner whom i am working on their behalf downloaded a bogus flash player update that came with everybody's favorite add on programs. Programs like OptimizerPro and that helpful guy with the headset that tells you to call to get rid of him. Anyway, I decided to perform a system restore. After which I ran scans with JRT, ADW, Malwarebytes, spybot, then i looked through startup options with Autoruns and all seemed well, until, he tried to log into his webmail. Some script error appears on screen, the error it's self is not so much an error as just a buch of code that tells me nothing. I used f-12 developer tools in Chrome and IE and found that one thing seems to stick out. First ill post the main error below.


', f ? f(document) : '') function color(s) { document.bgColor = s } function hint(s) { top.window.status = (s ? s : '') return true } var doc = document var form = document.form var form1 = document.form1 var form2 = document.form2 var errno = 0 if (arg.length > 6 && arg.substring(0, 7) == 'bgcolor') color(arg.substring(8, arg.length)) f = eval('parent.' + selfname + 'Init') if (f) f()



this really tells me nothing.  So with the f-12 tools i found this in the code under mbox.msc...


if (parent.mboxCB) parent.mboxCB()


I'm sure this is the problem. I searched the registry for anything close to that, found something in the DOM that referred to it and removed it. But that hasn't fixed the problem. I have reset IE to default removing all user settings. Deleted chrome user settings and re-installed chrome, no love.


Let me know what you need from me, happy to provide it to you. Thanks in advance!

As the Injector malware can be quite dangerous it is better to repost your Topic here.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/563350/js-injection-wont-go-away/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To avoid confusion, I am closing this topic. Good luck with your log.
