I have recently been attacked by a trojan virus and my OS is windows 7 64bit home premium so far right now seems all good no explorer.exe programs that taken over the task manager. My problem is that when i right click on the desk top and click screen resolution i get the error windows cannot find" make sure you type the name correctly. i know that the file is desk.cpl and so for reason seems that explorer.exe does not know the file name to open. and the other problem was that when i go to start a scan for malwarebytes it crash's before it can start scanning. I set the hard drive to a different computer and set it up as a external drive and did a few scan of norton for pass found 8 programs and the rest found none then i did a few scan's back in the system and found nothing i do admit i did you a registry cleaner but did not let it change anything in the registry i just used them to find what files were missing and pull it from a different computer. there are no programs that are using 100% cpu usage. when i go to open desk.cpl in windows folder nothing happens and another problem was that majority of my programs in control panel are gone and i can't click uninstall a program i have t
ran it with avast then ran it with norton on a different computer then now ran it with 10bit and threatfire and none of them find anything that would involve a virus. now i noticed when i went to go turn on windows defender the service kept stopping so im guessing you are right and there is still a virus in my computer just don't know where now im trying avg and see if that can help me pinpoint where it is but if i remove the virus would everything go back to normal or will i have to get the registry fixed i did a sfc /scannow and all it tells me it cannot repair rundll32.dll.
i checked all my processes in task manager and everything seems fine but still don't have any access to screen resolution only thing i've noticed in task manager that i count 18 and at the bottom left corner it counts 59 to 60 i don't know if there was much change from xp to 7 if the task manager shows all processes. and i have my second hard drive scanning on another comp that use's xp and it is being scanned by malwarebytes but I don't know if that is enough and it has a expired norton on there but yet it protects a little and i have it scanning under windows defender. so far no virus's i tried to install avg but i don't think i could get it installed ran into an error but don't remember what it was. so far i believe there are no viru's but what would be a really good free anti virus's i had both drives scan using trend micro trail of the antivirus and avg 2012 and they bring nothing and i did microsoft security essential's that showed the last two i believe but now im in a bind and don't have my 64bit cd til he send's it and i don't think i could rent a copy of windows 7 64bit and use my product key
