    I can take hard drive f out if it would help things.

    nod32 gives Operating memory - Win32/Olmarik.TDL4 trojan - unable to clean

    Customer built pc.
    I used to work in a IT dept of a call center but its all self taught. Im not the smartest but i do understand i dont know it all hehe or i wouldn't need help

    it all started when wife got a Virus called System restore so i followed the guide at

    started on the 8th but could have been 7th not sure. but my TDSSKiller log was ran on the 8th. i can rerun this if you think i should.

    I think i have removed everything with the system restore virus but this part but im not sure.

    1. on start up iexplore.exe will open and run but on the taskbar i dont see it open or cant never see the page so i close it in task manager. it will run ad's in the background so.
    1a. i use peerblock to keep those sites from doin things while i am doin scan's and such so i dont know if this will effect the out come.

    2. search's are redirected when clicked.
    3. load time of pages has slowed down like the network cant get the page too fast. but opening and closing programs seems to be about the same in speed.
    4. nod32 gives Operating memory - Win32/Olmarik.TDL4 trojan - unable to clean
    4a. nod32 is the only one out of about 5 that i have ran that see's this file.

    I have ran multi virus programs and such superantispyware will show some cookies up each time it scans but i lost the free trail to it last night i think. i have removed AVG and kaspersky trails as i switch from one to the other at this time i do have adaware and nod32 on the pc also maleware bytes still on the pc. i havn't removed superantispyware yet.

    I dont know if this will effect the outcome for combofix but i totally over looked where i need to put it on the desktop so i ran it from the firefox download folder it was saved. if this needs to be rescaned from the desktop i can redo this. but i will include that with my post here as i see it needed everywhere i read about it.

    will be posting some logs

    Thanks you for you help but it looks like i fixed it last night when i was up still trying a few things. heres what happened.

    Reading more into it and seeing it was inside the MBR i ran the aswmbr.exe and i did a fix mbr then i ran mbrcheck to see if it was still faked and it wasn't so i reran tdsskiller and it actully showed up 5 things this time one give me the option to cure the others i had to pick so i deleted them.. now this is where it got tricky but stuff that i have done before.

    I must have messed the MBR up by doin those step's or it could have been something tdss deleted so i would start the pc up and it would not boot at all black screen with a blinking line. so i tryed the win 7 disk to run the bootrec /fixboot and the other options but wouldn't fix it at all. so i went to my pc at the office where i have my copy of Partition manager by easus and created a bootable usb drive but you can only do this with the paid version not the free trail incase others read this.

    So i pluged it in and booted to the USB drive and i rebuilt the mbr from there again just to make sure then i had to set the system reserve partition as active applyed the settings and i was all ready to go no tdss comes back clear and nod32 doesn't show anything in the memory running so im running a full scan now. and checkmbr doesn't show faked anymore as well.

    After the nod32 i will rescan with malewarebytes to finish testing. If anyone else has this and reads this please confirm your reports when you are getting help because you dont want to have the black screen like i did because the avg.. user will have a hard time figuring it out. because you cant just search for the fix.

    since all scans are coming back clean now is there anything left i should do.
