Good day,
I have been battling a virus for 5 days now and I have been on the loosing side. This
Virus disabled my regedit, my task manager and even my antivirus software. It also restricts me
from going to Anti Virus websites like Trend micto Symantec and AVG , it even prevents me from
utilizing online antivirus scanners. I am a system administrator and I have already reformatted 16 computers then watch to my horror as they get infected again. Im losing my business and at my wits end. This virus shows up on my local temp files but when I delete it , it re appears with a different name. I already used combofix but to know avail. i have taken a screenshot of the virus and kept the log file. any help will be greatly appreciated. thank you

First please run HiJackThis and post the log file here... (also please do this after you've completed all the rest of this)
http://www.trendsecure.com/portal/en-US/tools/security_tools/hijackthis

OK, secondly download and run this quick little tool to re-enable Regedit and Taskmanager (and lots more stuff affected by malware).
http://www.majorgeeks.com/RRT_Remove_Restrictions_Tool_d5635.html

Now you've done that, on a clean pc download MBAM (malware Bytes antimalware) and it's updates from here:
http://www.malwarebytes.org/mbam.php
. Install MBAM and then the updates (it works like a normal software installer).
When finished updating, run a full scan. When it's finished, reboot IMMEDIATELY to prevent re-infection.

Then once you've rebooted, try and download SUPERantispyware from here:
http://www.superantispyware.com/
.
An quick scan should suffice (plus it has a pretty slow scanner), but if you like you can run a full scan.

Now download yourself some decent antivirus software. Try avast! from here
http://www.avast.com/eng/avast_4_home.html
. Update and scan...

Now run the scan with MalwareBytes AntiMalware (MBAM) and then with SUPERantispyware.

you might also wanna disconnect all computer in your LAN and start cleaning your server/main computers...then move on to other PCs. re-connect them to the lan after you're sure that those PCs are CLEAN.

Goodluck. I've had my share of viruses that disables taskbar, regedit, anti-virus softwares, and access to the internet. Dont loose hope! Be patient, concise and persevere. I've cleaned my PC without resorting to reformating, im sure you can too.

She's the only one I fear, my princess wrapped in shadows, my princess beloved.

Thank you for the encouragement. Finally I was able to determine what virus infected my computers. Its the Win/32 Sality worm. I heard alot of people saying that this is very difficult to remove, any advice ? thanks. using the MBM and antispyware didint work, NOD32 did remove some but still could not find the worm itself hidden somewhere. It also prevents me from booting on safe mode.

Since this virus is well lodged into your system, I recommend using a boot CD. Use the Avira Rescue System
http://www.avira.com/en/company_news/rescue_cd_.html

Burn the .iso to a CD. Leave the CD in the drive and reboot your pc. Press 2 to start the avira system, a load bar will start to scroll and may get stuck around 80% for a couple of minutes, just leave it. Press your down key on your keyboard to hover over english, and use the space bar to move the 'x' and select it. Then run the scan, and all infected files will be renamed to 'whateverthefilewascalled.oldfileextension.XXX'. EG. 'worm.exe.XXX' When you reboot your pc, run a search from the start menu for '.xxx' and delete anything found.

I have moved your HijackThis log to the HijackThis Logs and Malware Removal forum as they are not permitted in this forum. Please go here, click on the Options button in the upper right corner of that thread and choose Track this topic. Subscribe to that topic to ensure you are notified when a helper replies.

Now that your log is posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic.
