whenever my comp opens, it says

Error loading C:\WINDOWS\System32\395705.dll
the specific module could not be found

my comp's working real slow, not able to download any antivirus, all existing antivirus programs are not working, and it says everytime i open the computer, that your comp has recovered from a serious error. the last two times my comp stopped working after this same message was shown a couple of times. thats why i am getting hysteric as i cant afford to lose all my data.

i have installed the Hijackthis thing and i have the log but i dont know what to do now. the log is:

Hello pragya,

I am sorry to give you some very bad news. :thumbup2:

Your System is infected with Virut!!
Virut is a file infecting virus which is able to modify itself each and every time it runs. In addition, when it infects, sometimes it will destroy the file it tries to latch onto.
For these reasons, you really can't truly fix Virut. You will need to format/reinstall the operating system on this machine.

More information:

There are bugs in the viral code. When the virus produces infected files, it also creates non-functional files that also contain the virus.


W32/Virut.h is a polymorphic, entry point obscuring (EPO) file infector with IRC bot functionality. It can accept commands to download other malware on the compromised machine.
It appends to the end of the last section of executable (PE) files an encrypted copy of its code. The decryptor is polymorphic and can be located either:
Immediately before the encrypted code at the end of the last section
At the end of the code section of the infected host in 'slack-space' (assuming there is any)
At the original entry point of the host (overwriting the original host code)

Miekiemoes, an expert  for malware removal, and an MS-MVP, additionally has a blog post about Virut.

I suggest you to start backup all of your valuable data/documents/pictures/movies/songs/etc..
Do NOT backup any applications/installers and Do NOT backup any .exe/.scr/.htm/.html/.xml/.zip/.rar files...
This because these files may be infected as well. If you back them up and replace them afterwards, it will infect your computer again.
