[ScHmIdTy56789]

so the title says it all, so i restarted my router because it was running like shit... so i turned off the computer and the next day i get on it comes up with this firmware update and it keeps saying i need to turn off my firewall for it too work, so i was a little suspicious so i got McAfee going and i did a scan and it says i have a trojan. mcafee got rid of it but everytime i do a scan now it comes up with a trojan. and whenever i start up the computer it comes up with that you need to update your firmware for your router and saying that i need to turn off my firewall setttings........ what do i do to get rid of this constent thing?.. plus my computer has been running a little bit slower, if that helps any.....

Trojan is a virus that hides under name of safe brand / program. It probably sits in your boot sector of PC, running everytime after PC starts. NEVER do what it asks you for, your PC will get infected

Download Malwarebytes Anti-Maleware, and run a quick scan, then a full scan ( if you have time) , it might be a false positive ( Mcafee is crap and detects legit programs as viruses/trojans/ etc and when you look up the name it doesn'nt even exist).

the malwarebytes thingy is pretty good and it doesnt matter if you have time to run a full scan or not..YOU NEED TO TAKE THE TIME (deep scan etc..)
anyway, here are some other steps:

• download hijackthis too and run it (analyze the log file on the homepage)
  
• and for future references: use a sandbox/VM to test suspicious files
  
• hit win key + R and type in msconfig -> systemstart and remove all marks from programs that you definitely dont know (google for *.exe that you dont know before you unmark them)
  
• open hosts file and clear it up

I really dont want to know why you have a condom in your computer....

Seriously, if it doesnt go away when you're using MBAM download rkill then use MBAM again.
