Avast blocked process svchost.exe, blacklight.info

Viruses and worms
1

Hello all, I found my way here through a Google search. I asked a question in this topic: https://forum.avast.com/index.php?topic=167332.0 but was asked to start a new topic along with my logs.

Here is a brief description of my problem.

I am running Avast Free, and it pops up a warning that it has blocked scvhost.exe which is trying to download a .DLL file from blacklight.info

I have downloaded and run rkill.com but it does not find any problems - yet Avast keeps popping up these messages every time I get an internet connection! Combofix from Bleeping Software does not support Windows 8.1, and there are stern warnings that it may damage my PC if I run it in compatibility mode.

I am running Windows 8.1 on a Lenovo X1 Carbon, and using Chrome browser.

I am also unable to find the AVAST logs. There are no *.log files in the AVAST directory, or any of its subdirectories. *.txt shows quite a few files, but I don’t know which one is the log. What is its name?

Attach your basic logs. (MBAM, FRST and aswMBR…!!)

Thanks for your help, Asyn. I have downloaded those programs and run them. Here are the logs.

This forum only lets me post a maximum of 4 attachments at once. Here are a couple more.

The first is MBAM after I clicked the “CLEAN NOW” button.

The second is the log from rkill.com

Save this as fixlist.txt, in the same location as FRST.exe

Run FRST and press Fix
On completion a log will be generated please post that

That’s great, it appears to have worked! I applied the fix, created the restore point, and the machine rebooted. No more notifications about blacklight.info

Thank you so much!

Any further problems ?

Close to 24 hours after I applied your fix and the warning hasn’t popped up again. So touch wood, it all looks good. Thank you so much.

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:
