Thеrе іѕ a .dll іn mу system32 file thаt seems tο keep οn remaking itself whісh means thеrе′s a backdoor program οn thіѕ system. I’ve tried Kaspersky bυt thе .dll seems tο ѕƖοw mу computer down thаt whеn I try Kaspersky mу laptop doesn’t load up whеn іt comes tο thе desktop. I’ve tried Ad-Aware, Pest Control, Nod32, аnԁ AVG. I’ve аƖѕο tried tο remove іt forcefully bυt іt ѕауѕ іt’s іn υѕе. Whеn I remote іt wіth a сοƖԁ boot іt remakes itself whеn I restart mу computer. I ԁіԁ thіѕ іn Safe Mode. Anу tips οn tο remove thіѕ annoying bugger? I аƖѕο tried googling thе .dll bυt nothing comes up, here іѕ thе dll
vtUlLDst.dll
Iѕ thаt even a legit system32 dll bυt infected? If іt іѕ wουƖԁ I bе аbƖе tο mаkе a nеw, сƖеаn system32 οr іѕ reformating mу οnƖу option?
HеƖр needed! Thanks іn advance.

i’m by avira..antivirus..it searched & ruined 456 threats in my laptop
works for me
first off just because the dll reappears doesn’t mean u have a backdoor installed it may possibly mean there is a code most likely by a loop to check for the existence of the object and re-erect it ,, those are usually in the registry startup locations,, it may also be some function hooks involved in where ur antivirus may be disabled or wounded basically what u need is a fresh binary thats not infected, u can’t trust ur AV nor the functionality of the OS at this top,, u need to make a LiveCD by Nero or infrarecorder or knoppix or a similar live linux CD with NTFS modules built-in and a antivirus like ClamAV,,, u boot into the live CD and run a the AV,, the AV should notice ur windows hard drive even thought the OS is dead,,, it should also be able to configure networking for u and update the AV program for u to run a scan on the windows partitions,,, this should be all means find the infection and give chance to remove,, another thing u can do is just delete the files and every instance of the code from the system by the Live CD’s file browser,, they wont return when the drive is dead because the Os is not alive,, but u must know the locations of registry hives on the system which u can google, k and u should also have the sysinternals suite installed to be able to locate the infected binary names and investigate their locations
Well its not a trojan or adware. its a virus obviously by that description.
if that viri is not defined, if its new, scanning you’re HDD would be a waste of time.
Removing it manually can be to risky. you make one mistake in its registry and you can hurt you’re computer or even kill it.
reformat may possibly be you’re only option
u know what dude i tried what u said and google it and yeaa u r right,i have an thought,,i reflect u can mail ur issue to one of the antivirus company’s like mcafee or symantec all those ,and i reflect they will react with u ,,,,may be this is a new spyware or backdoor try it
