It sounds like the "Zeus" virus or whichever one you got loose on your network may have secretly copied itself to one or more of your other computers commonly connected through your router. This happens quite frequently, and many of my Clients who've had this usually give up after they spend hours or even all day on the phone with their ISP tech resetting the router only to get it immediately infected again right after the reset because they left 2 or more computers connected to the modem-router when they performed the reset.
How many computers did you have connected to the router when you did your reset? The correct answer should have been
"1" and only
"1".
Did you remember to check for and install updates to both your AV and to Malwarebytes prior to the reset on all computers?
Is your Modem-router one single box (combines both Modem & router functions), or is it 2 boxes, such as 1 box for the Modem function (usually supplied by the ISP, in this case the Cox box), or do you have 2 boxes; 1 Modem box and another Router box (such as Cisco/Linksys or Netgear)??
The correct procedure here is that if you have 2 separate boxes, is to first remove the Router box cable from the back of the Modem box, and plug in only 1 computer there; repeat the Modem reset procedure. Then immediately re-scan that 1 computer with your AV and Malwarebytes. Run that computer for at least 48 hrs. without changing your setup, check for any script errors. If none are found, you can assume the reset of the Modem box and virus scan/removal was successful,
and hook up Router back to the Modem box and reconnect your other computers 1 at a time, repeating the AV & Malwarebytes updates check and scan on each machine, checking for script errors again. If none are found, you have then eliminated the virus!
If you have a combo Modem-router box (which it sounds like you might have), then the procedure is almost the same; you should remove all of your computers except the Main computer you use to communicate with the combo box. If you can connect into the Combo box's Admin utility, you should temporarily disable
WIRELESS RADIO on that Combo box*. Check for updates on your AV and Malwarebytes once more on that computer, disconnect it from the Modem-router combo box, and reset it per Cox's instructions from the other day. Then reconnect the same computer you just had, and re-run your AV and Malwarebytes scans once more. Test that 1 computer for 48 hrs. again, browse to various websites, check your E-mail, etc. If no script errors are found, then you've removed the virus from the Combo box and that 1 computer. At this point, you can then reconnect your Router to the Combo box, and hook a 2nd computer to your Router and scan that machine, and retest. You'll have to repeat that procedure for each additional computer you re-connect via hard-wire Ethernet cable to the Router to make sure you've removed the virus from each subsequent computer. This should eliminate the virus from your network!
*This is a lot of work I know, but it's important to have the
WIRELESS RADIO off in your Combo box (Modem-router) when you attempt this part of the repair, as if you have wireless devices such as laptops, tablets, smartphones, etc. turned on in your home they can receive a copy of the virus as soon as you reset your Combo box! And then the virus can re-transmit copies of the virus back to the Combo box you just reset, and the Combo box then copies the virus back out to all wirelessly connected devices attached to the Combo box before you know it--you're reinfected; this all can happen in seconds.
That's why it's important to disable it. And, not all people are running AV software on their tablets or phones. Most laptops have AV either built in or 3rd party, so they are not at risk as long as the AV software is updated and running. It's the tablets and smartphones that are at risk. I run Avast on my phones and tablets to prevent this.
Troubleshooting this way, you isolate the virus to hard-wired connected devices only, and remove them 1 device at a time. Then, once the symptom of the script error is removed from play on your hard-wired devices, you can proceed to re-enabling the wireless part of your network and reconnect wifi devices 1 at a time, repeating the AV update and scan procedure for each wifi device and testing. If you do all of this on the wireless network and no other devices begin showing script errors again, you've then removed the virus from the wireless as well as wired portions of your home network and you should be fixed!
I've fixed a few of these, and since some of these viruses are transmitted to PCs and laptops via use of a Rootkit or Bootkit, you have to use separate programs to detect/remove these, you may have to download these tools (TrendMicro RootKitBuster for example), and repeat the whole process again from the beginning. While you are running the first portion of the removal process on the wired-only computers, if the virus comes back and script errors reappear on any connected computers or subsequently connected computers, you may have to erase the hard drive and completely reinstall the OS on each connected computer that shows it's been infected or re-infected.
*ENSURE YOU HAVE BACKED UP ALL YOUR PERSONAL DATA TO EXTERNAL MEDIA FOR EACH COMPUTER YOU HAVE TO WIPE AND PERFORM A WINDOWS REINSTALL ON PRIOR!"* as mentioned in
POST #6. This is the "Big-Hammer" solution, and only to be used as a last resort. If you have 3 or more computers (desktops, laptops), this could take you weeks to achieve unfortunately. If you follow my advice here, you may be able to remove the virus from your network without having to reinstall Windows on all your machines--but, don't count on it. Router viruses are extremely difficult to remove from home networks and even more difficult on business or corporate networks. And they usually take an expert in networking to do so.
Hope this helps you.
Best of luck,
