trojan problem

Norton just downloaded the latest refresh with LiveUpdate and
immediately flagged a file called wincvs0.dll as a backdoor trojan,
couldn't quarantine, couldn't repair and couldn't delete. Upon
reboot, it's now detecting a file called wincvs1.dll and wincvs0 has
disappeared. It behaves as above with no delete possible. Norton
"knowledge base" doesn't show anything about that file and a search on
the internet doesn't reveal anything about any file called "wincvs".
a search of the registry finds it in 2 places under userkey. In one
location it is listed along with several other files that were
downloaded off the internet and at the other location it is listed at
HKEY_USERS\S-1-5-21-336809978-847386435-1484400983-1005\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSaveMRU\dll
with the entries:
Name: a
Type REG_SZ
Data: C:\WINDOWS\wincvs1.dll

and
Name: MRUList
Type: REG_SZ
Data: a

Anybody know what is going on and how to delete this beastie? Any
suggestions??
thanks,
bumblebee
 
1) Download the following three items...

Trend Sysclean Package
http://www.trendmicro.com/download/dcs.asp

Latest Trend signature files.
http://www.trendmicro.com/download/pattern.asp

Adaware SE (free personal version v1.05)
http://www.lavasoftusa.com/

Create a directory.
On drive "C:\"
(e.g., "c:\New Folder")
or the desktop
(e.g., "C:\Documents and Settings\lipman\Desktop\New Folder")

Download SYSCLEAN.COM and place it in that directory.
Dowload the Trend Pattern File by obtaining the ZIP file.
For example; lpt246.zip

Extract the contents of the ZIP file and place the contents in the same directory as
SYSCLEAN.COM.

2) Update Adaware with the latest definitions.
3) If you are using WinME or WinXP, disable System Restore
http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm
4) Reboot your PC into Safe Mode
5) Using both the Trend Sysclean utility and Adaware, perform a Full Scan of your
platform and clean/delete any infectors/parasites found.
(a few cycles may be needed)
6) Restart your PC and perform a "final" Full Scan of your platform using both the
Trend Sysclean utility and Adaware
7) If you are using WinME or WinXP,Re-enable System Restore and re-apply any
System Restore preferences, (e.g. HD space to use suggested 400 ~ 600MB),
8) Reboot your PC.
9) If you are using WinXP, create a new Restore point

OK, well, I guess I actually searched for wincvs1.dll and wincvs2.dll.
and it comes up with 0 hits on the couple of search engines just
tried, including google. WinCvs appears to be some sort of program
that I don't have.
thanks,
bumblebee
 
You know, I noticed your standard answer on a couple of other threads
in this and other groups and I tried to get all the files earlier
today and had problems on the web sites...I'll try again and let you
know...
thanks,
barry
 
Thank you!! Are you sure you have to create one with XP?? Not being a user
of that O/S, I am not sure........but thought I would ask.

OK, David if you're still with me...
I cut off system restore, did a SAFE MODE boot, selected
administrator, ran Sysclean (which took 26 hours BTW) and gave me a
log with a bunch of info. Then I ran Adaware and it found 133
bugs/viruses, I looked over the list (none of which was the file I
asked about originally =wincvs1.dll) and quarantened then deleted the
files.
Then I rebooted, went to regular boot and ran AdAware (couldn't keep
the computer offline another 26 hours for sysclean at this time) and
it found another 84 files, two of which were wincvs1.dll at the same
location. I quarantened those and deleted, rebooted and re-ran
adaware and nothing showed up. I went to the internet and immediately
wincvs1.dll was flagged by norton. I disabled norton and reran
adaware and nothing showed up. In the mean time I rebooted and even
though norton was disabled, it was still screaming ALERT! regarding
wincvs1.dll.
That's where I stand now. BTW, my computer ran faster after the
session with Safe mode until norton flagged ALERT! on the wincvs1.dll
file and then the system slowed down.
Any Ideas what is going on?
BTW, it took 26 horus because I have the largest Hard drive made
partitioned into the largest partitions windows would recognize and
another hard drive with the largest size windows would recognize and
all are 90% full.
thanks, for any advise!!!

26 hours is a log time. However, slow computers with large hardisks give this result.

All I can say is you have to do this in a few cycles.

Before you scan in Safe Mode, make sure all programs have been shutdown or use MSCONFIG.EXE
to not have programs start when rebooted.

Since I posted the last, my computer wouldn't boot when I returned
from work. No bios, nada. Rebooted several times, tried jiggling all
connections on motherboard and then was able to get the bios intro
screen and nothing else. I was able to get into the bios and all
sorts of settings had been changed (hard disks labled "disabled"
etc.). I changed what I could see was wrong and was able to get into
my hard drive but not my partitioned secondary drive. Ran ad-aware
from windows and it only found one bug. Ran SysClean which apparently
from the log could not delete what it wanted to delete, could not
move, etc. Ran both repeatedly. and that .dll file is still there.
BTW, I have a 1.8g thunderbird AMD chipset so it's not really slow.
Thanks for your help, think I'll try that Kaspernsky program and AVG
with Ad-aware and see what happens...

Sounds like the battery that backs the CMOS (BIOS) settings needs replacing.
