Hi!
This is the first time I've actually posted anything on this site, I've used it before to help me remove a rogue security malware off of my laptop, and it worked very well, So I am hopeful this community may be able to help me with my problem on my new computer.
I've had it for a couple of months, and nothing major had happened to it in the way of malicious software, until a few days ago.
I was hit by a pretty bad google redirect agent, effectively removing my ability to use search engines- I looked at all of the usual places where redirect stuff came from- checked the hosts file in drivers of system 32, I scanned my system with Avast! and Malwarebytes- and nothing.
I also have a much bigger problem, but I will get to that after I tell you what avast keeps doing.
So, in response to being hit by whatever this could be, I tried to buy a renewal to Mcafee, only to find they didn't take debit cards, so I looked online for a new solution, I chose avast, and bought a year subscription to their most advanced suite. Ever few minutes, I'm hit with a threat detected alert, saying that the threat was moved to my virus chest, but a couple minutes later, same thing happens, exact same file name that was removed. The file is
C/Windows/Installer/{e4d3cf76... (It goes on for a while)
I figure this has to be some kind of virus or something that can't be easily removed, I mean, I don't even have an installer file in the windows file.
Avast says it is something called 80000032.@

Now for my biggest problem: As I'm typing this, every 30 seconds or so my screen acts as if I have clicked away from my current tab, and I have to click on it again (Or press space bar) to resume scrolling through a page/typing something. The absolute worst is with video games. Now whenever I try to play a game it minimizes every 30 seconds to two minutes, without my consent.
Is this caused by the same thing? What am I infected with? How can I remove it?
Any information would be greatly appreciated, especially on how to get rid of this annoyance, and thanks for reading!

Welcome aboard Posted Image

Please download the below tool named Rkill (courtesy of BleepingComputer.com) to your desktop.

There are 2 different versions. If one of them won't run then download and try to run the other one.

You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

http://download.bleepingcomputer.com/grinler/beta/rkill.exe
http://download.bleepingcomputer.com/grinler/beta/iExplore.exe

  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista or Windows 7 right-click on it and choose Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • Do not reboot until instructed.
  • If the tool does not run from any of the links provided, please let me know.

If normal mode still doesn't work, run the tool from safe mode.

When the scan is done Notepad will open with rKill log.
Post it in your next reply.

NOTE. rKill.txt log will also be present on your desktop.

This infection will require elevated help.

Please follow the instructions in ==>This Guide<== starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

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