Malicious URL Blocked keeps popping up.

[Mishax]

Hello.

I know next to nothing about computers so I have no idea what is going on. For the past few hours the pop up saying 'avast malicious url has been blocked' has been popping up several times. I only visited three sites today and it even happened in google search. They are sites I've been on for years and this even came up on my gmail. Some of the urls that avast said that were blocked were also third party tracking cookies I have disabled on these particular sites so maybe that has something to do with it?

I really have no idea and have done a full scan with avast as well as a boot scan. I've even scanned with Malwarebytes and attached the log but it came up clean. On my mom's computer the same thing happened when she was on her yahoo mail so I'm wondering if it could be a thing with avast. I'm really just at a loss because like I said I know nothing about computers.

Thanks!

follow this guide and attach (not copy and paste) the requested logs   http://forum.avast.com/index.php?topic=53253.0

1. AdwCleaner
2. Malwarebytes.   the one you posted above was not updated before scan
3. OTL
4. aswMBR

when done the removal experts will be notified. It may take hours before they arrive so be patient

So far the problem seems to have stopped after an avast update but here are the logs as requested.

Now everything is added.

I opened the program and pasta the text into the box. Then I clicked "Run Fix". After that my screen went blue and my computer shut down. When it came back on it said that my computer had been shutdown improperly and my desktop icons were all messed up. My normal programs which come up automatically are also gone. I can't even find the program when I search for it. What should I do now?

[Mishax]

Here is the attached the log. I managed to run the program again and it worked but I'm a little confused as to why the blue screen saying there was a problem with my computer popped up and it restarted suddenly on the first try.

[Pondus]

Did you read the red warning at top in essexboys post

[Mishax]

Ah I did but I'm just ultra paranoid.

Everything seems to be working okay now so far though.

[Pondus]

Essex will check the last log when back,  and if all is ok remove the programs used

[essexboy]

Subject to no further problems   

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:

: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
