Hello, I am getting pop up messages from Avast (free) telling me that a threat has been detected in svchost.exe.

I am running Windows 7 Home Premium (64 bit) on an Asus laptop.

I have seen several forum posts about "svchost.exe" but they all seem different, and I am not sure what to do.  Avast told me I would have to buy their software ($100+, not do-able for me right now).  I have been regularly using the trial of AVG also, but my trial ends tomorrow and it has not detected the virus/malware anyhow.  I am currently running the free version of Malwarebytes (it's been going for just over an hour) but has not found it.  Can anyone tell me what I should do?
(Pictures below are screen captures when someone from Avast was remotely looking @ my computer - the first is the top of the screen he pulled up, the second is the bottom; I didn't have time to copy the whole thing.)

Thank you so much in advance to anyone who may have some advice for me!

"Show advanced settings..." link. Scroll down to find the Downloads section and click the Change... button. Select your desktop and click OK.

Mozilla Firefox - Click the "Open Menu" button in the upper right-corner of the browser. Choose Options. In the downloads section, click the Browse button, click on the Desktop folder and the click the "Select Folder" button. Click OK to get out of the Options menu.

Internet Explorer - Click the Tools menu in the upper right-corner of the browser. Select View downloads. Select the Options link in the lower left of the window. Click Browse and select the Desktop and then choose the Select Folder button. Click OK to get out of the download options screen and then click Close to get out of the View Downloads screen.
NOTE: IE8 Does not support changing download locations in this manner. You will need to download the tool(s) to the default folder, usually Downloads, then copy them to the desktop.

Follow the instructions in the following link to show hidden files:

Next,

Please open Malwarebytes Anti-Malware.

  • On the Settings tab > Detection and Protection sub tab, Detection Options, tick the box "Scan for rootkits".
  • Under Non-Malware Protection sub tab Change PUP and PUM entries to Treat detections as Malware
  • Click on the Scan tab, then click on Scan Now >> . If an update is available, click the Update Now button.
  • A Threat Scan will begin.
  • With some infections, you may see this message box.
'Could not load DDA driver'

  • Click 'Yes' to this message, to allow the driver to load after a restart.
  • Allow the computer to restart. Continue with the rest of these instructions.
  • When the scan is complete, click Apply Actions.
  • Wait for the prompt to restart the computer to appear, then click on Yes.
  • After the restart once you are back at your desktop, open MBAM once more.
  • Click on the History tab > Application Logs.
  • Double click on the scan log which shows the Date and time of the scan just performed.

If Malwarebytes is not installed follow these instructions first:

  • Double-click mbam-setup and follow the prompts to install the program.
  • At the end, be sure a checkmark is placed next to the following:

  • Click Finish. Follow the instructions above....
Next,

Download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.
Let me see those logs in your reply....

Thank you,

Kevin...
