OBFUSCAT variant & Houscall scan

by dzdon / March 14, 2007 1:29 PM PDT

Ok, I'm back, this time with another threat found using TrendMicro House call.
I thought I'd try it since it's been mentioned to help find unwanted things...
The results said it was a possible OBFUS..."suspicious file that manifest behavior and characteristics similar to known OBFUSCAT variants"

I couldn't remove it automatically. It gave me two choices to try and neither could remove it completely. It also gave the option to remove it manually...which I had to re-read a few times to understand, and I'm still not totally clear on manual removal of malware.

I guess my question is what to do now that the scan is over and it cannot remove it completely?? and I just closed the site?? Not really sure if it was completely finished.
I'm not familiar with that online scan and it would just read "idle" in step #3 and give the same two options for what to do next (auto remove or select parts--I think were the choices, then click next/fix)...nothing changed in the results... The only option was to try to fix the threat...which just came back saying it couldn't be removed and go back to the auto remove or select parts then next.

Did I miss something in the scan?? Not wait long enough?? Is there a end screen that let's you know when it's complete??

Sorry my description is a little lame and not very specific. I can try the scan again and write more specifics down if needed.

I'm just not familiar with dealing with trying to fix threats found...actually the whole self scanning and checks is new to me as I previously relied on my all-in-one-Earthlink so I never saw so much information on these threats or computer talk for that matter! I'm learning as I go!

Any more help/advice is always appreciated!

Malware type: Trojan
Aliases: No Alias Found
In the wild: No
This is the Trend Micro detection for suspicious files that manifest behavior and characteristics similar to known OBFUSCAT variants.

To view sample detailed analyses of OBFUSCAT variants, refer to the following links:


I suggest you run the following scan to see if you really have the said trojan:

Downlad AVG Antispyware (freeware) from http://free.grisoft.com/doc/5390/lng/us/tpl/v5#avg-anti-spyware-free (scroll down the page and look for avgas-setup- to download the free version)

After installation, update the program then run a full system scan.

See if it find and fix any malware (trojan, spyware etc) then let us know how it goes.

"I guess my question is what to do now that the scan is over and it cannot remove it completely"
Housecall should show you a page that says it has finished cleaning the computer. If not, there must be a glitch in the server that halts the cleaning process or the trojan is maybe actively running that maybe blocking the cleaning.

You can try first scanning using AVG antispyware. If you want to try Housecall again, try another Housecall server or link:

I do have the AVG antispyware and have been keeping that updated and used for scans...their scan has not found this malware...I will update and scan agian with the AVG antispyware.

Depending on what that may find or not find, I will try another link to Housecall and try it again.

Thanks again for your help!

Hope you'll succeed in running it without issue

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
