I have a Dell Dimension 2350 (new hard drive ca. 2006), running Windows XP SP3 Home Edition. Intel Celeron 2G, 512 RAM, with Avast! Antivirus, and regular Malware Bytes updating, less regular scans. I use Firefox and NoScript, also run Process Explorer every time I turn the computer on, and occasionally use it to shut down processes.

About 2-3 weeks ago, I began to notice high physical memory usage (e.g., 80-90%) that didn’t appear to be explained.

On November 1st, I was online (Firefox), and noticed a white flash on my screen. Suddenly a Mega-Zipper (my software to open .zip files) window popped up. I clicked on the “close” button, and hit Process Explorer to find out what was happening. A “packed image” named installer_no_upload_silent.exe was running. I used Process Explorer to shut it down.

Next, a “cmd” line showed up on Process Explorer, with a file (Installer_msi_win.msi)underneath it (no company listed, but “collecting information for Microsoft” as the description).

This happened three times that day, in the same sequence. Each time Firefox was running. I updated Malware Bytes & Avast!, rebooted into safe mode, and ran a full Malware Bytes scan . The scan showed nothing infected.

A Google search has showed 1 occurrence of “installer_no_upload_silent.exe.” on a Portuguese-language website similar to this one, from a couple of days prior to my attack. In that case, a Malware Bytes full scan showed three registry keys infected, all in the Microsoft Security Center, all resolved by the full scan.

I have gone online once since the 1st, to ensure updates to Malware Bytes & Avast!, and have run another full scan (in normal mode), and again nothing was found. Ccleaner registry scan shows “obsolete software key” for Mega-Zipper.

During my one online trip after the 1st, Mega-Zipper came on again without popping a window – I found it only because I was monitoring Process Explorer, and used PE to kill it.

I will download a (hopefully) clean version of Malware Bytes, as mine has clearly been compromised, will reboot in safe mode, and run another full scan. I will not be online from this computer often, and will likely monitor any responses from a public computer. Please do not take silence on my part as resolution of the problem – I’ll report success, if achieved.

Bad bug.

I'm confused -- should I post, or not post, the dds.txt and attach.txt? Instructions say post, text of the doc itself says don't post unless specifically requested.

Tried downloading a "clean" Malware Bytes & doing a full scan (normal mode, but off-line), came back clean again. Found Mega-Zip trying to install the Installer_msi_win.msi again (twice), found the svchost service under which it was being installed was Akamai, killed the svchost, haven't had the installer come back since. (And I'm watching.)

Have done, thank you. Another Google search has turned up some additional hits, including this one Just an Akamai service, no worries and this one Troj.Downoader.W32.Aphex.020. Glad I'm not the only one who's puzzled.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic426185.html 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 MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in 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 MRT 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 MRT Team members are EXTREMELY 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 make another reply until it has been responded to by a member of the MRT 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 MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To avoid confusion, I am closing this topic. Good luck with your log.

Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
