Zeroaccess Trojan Infection


Recommended Posts

I suspected I had some kind of virus last night after a wierd slow-down on the web. I ran a full scan and nothing was found, however after the scan messages from my antivirus keep popping up saying that a trojan has been removed. They pop up every 5-10 seconds and have not stopped for about 12 hours now. The popup claims the trojan to be a zeroaccess trojan located in C://$Recycle.Bin\ and then there is just a nonsensical alphanumeric file name. I ran MBAM and it said that there were 3 files removed however after a restart the popup persisted. I have McAfee antivirus and 64-bit Windows 7. The Log files from dds are attached.

Welcome to the forum.

Please remove any usb or external drives from the computer before you run this scan!

Please download and run RogueKiller to your desktop.

For Windows XP, double-click to start.

For Vista or Windows 7, do a right-click on the program, select Run as Administrator to start, & when prompted Allow to run.

Click Scan to scan the system.

When the scan completes > Close out the program > Don't Fix anything!

Don't run any other options, they're not all bad!!!!!!!

Post back the report which should be located on your desktop.

And no more antivirus popups!!!! You are a life saver!! I had a paper to write and my computer was slow and unuseable and now i can finish it! All appears to be fixed and the computer speed is back up to normal. Please PM me with a price that you think is a fair donation for your services. I really appreciate the time you have put in to help me remove this trojan.

You have out dated programs on the system which are vulnerable to malware.

Please update or delete them

Info on doing that can be found in my Preventive Maintenance below.

~~~~~~~~~~~~~~~~~~~~~~

A little clean up to do....

Please Uninstall ComboFix: (if you used it)

Press the Windows logo key + R to bring up the "run box"

Copy and paste next command in the field:

ComboFix /uninstall

Make sure there's a space between Combofix and /

cf2.jpg

Then hit enter.

This will uninstall Combofix, delete its related folders and files, hide file extensions, hide the system/hidden files and clears System Restore cache and create new Restore point

(If that doesn't work.....you can simply rename ComboFix.exe to Uninstall.exe and double click it to complete the uninstall)

---------------------------------

Please download OTL from one of the links below: (you may already have OTL on the system)

http://oldtimer.geekstogo.com/OTL.exe

http://oldtimer.geekstogo.com/OTL.com

http://www.itxassoci...T-Tools/OTL.exe

Save it to your desktop.

Run OTL and hit the CleanUp button. (This will cleanup the tools and logs used including itself)

Any other programs or logs you can manually delete.

IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST, etc....

-------------------------------

Any questions...please post back.
