Hi,

I was having some problems with a whole host of trojans that had taken a
hold of my computer. I did have uptodate antivirus and it was effective in
finding and removing them, however one of them always managed to evade this
and would bring up a message once I had logged on. Its process name was
winupdate86.exe which was always in the folder System 32 in the Windows
folder. this process blocked the task manger and the registry editor but with
Windows defender i was able to look at the currently running programmes and
see that it was this winupdate86.exe that was the cause.

I then also noticed an exe programme that was on the startup list called
winlogon86.exe which i thought was the reason that this winupdate86.exe was
always there whenever i switched on my PC. and so i deleted it.

Now when i switch on my PC i can get to the welcome screen and then when i
click on the account(there is only one account) it says "logging on" then it
just logs off...hence i think i have deleted a critical file for the logging
on process.

I do have the Windows recovery disk from Dell and easy option would be to
reset to the factory settings. but if i could use the recovery console to
just repair the logon file I dont have to lose my work.

Is there anyone out there who can tell me the spcific code lines to use to
repair/copy a file. I have used the chkdsk command but as i have no knowledge
of command promt i am stumped as to what to do next.

Please help
Many thanks

If you literally have, or had, a "whole host of trojans," it's highly
unlikely that you can fix what you have, and your only real solution
is to reinstall Windows from scratch.
