I have been struggling to identify a problem on my son's computer. The first symptom was the inability of any program to download any file or update. This problem included ITunes, AVG antivirus update, MalwareBytes update or installs for the online games my son likes to play (which probably lead to this problem in the first place - I know, don't remind me). The downloads would truncate after 16 to 24 megs even if the file size were larger. I disabled AVG and MalwareBytes and ran ComboFix.exe. Once that was done, I was able to get AVG to update and scan - but it did not detect anything.

The strange thing is that I cannot access any download page from my son's computer - for instance - I go to the MalwareBytes home page, click on the download link and the browser gives me a page not found message. Same thing happens if I go to another anti-spyware download page, such as Lavasoft's Adaware.

I used my computer to download a new malwarebytes install, removed the old one from my son's computer because it gave me the message that the setup files were corrupt when I tried to perform an update - I was able to install the latest version and run an update - but as with AVG - Malwarebytes detected nothing after a full scan.

I installed HiJackThis.exe and ran a diagnostic - and have appended the log file content to this post - I do not see anything that jumps out at me but perhaps someone else can help.

I am scratching my head at this point and hope I can get some assistance here because otherwise I have to do a clean wipe and OS re-install as a last resort.

Hi and welcome to the forum!

Please create a NEW post in the HJT forum as shown below even if you can not run any scanners. The helpers don't work on Malware and Logs in the General forum.
Also please note that they are VERY busy at the moment and though they would love to assist you immediately, there are too many users requesting help at this time which has caused response times to greatly increase. It could be a few days before someone responds to your post so please try to be patient while they catch up to the requests. Also, please don't respond back to your post until a helper has responded. This will change your post count and could lead the helpers to think you have already been helped. Thank you



Scan and post logs - read note at bottom in green
If you're having Malware related issues with your computer that you're unable to resolve.

1. Please read and follow the instructions provided here: I'm infected - What do I do now?
2. If needed please post your logs in a NEW topic here: Malware Removal - HijackThis Logs
3. When posting logs please do not use any Quote, Code, or other tags. Please copy/paste directly into your post and do not attach files unless requested.


* Please do not post any logs in the General forum. We do not work on any logs posted in the General forum.
* Please do not install any software or use any removal/scanning tool except for those you're requested to run by the Helper that will assist you.
* Using these other tools often makes the cleanup task more difficult and time consuming.
* If you have already submitted for assistance at one of the other support sites on the Internet then you should not post a new log here, you should stay working with the Helper from that site until the issue is resolved.
* Do not assume you're clean because you don't see something in the logs. Please wait until the person assisting you provides feedback.
* There are often many others that require asistance as well, so please be patient. If no one has responded within 48 hours then please go ahead and post a request for review


* NOTE: If for some reason you're unable to run some or any of the tools in the first link, then skip that step and move on to the next one. If you can't even run HijackThis, then just proceed and post a NEW topic as shown in the second link describing your issues and someone will assist you as soon as they can.
