Avast 'Infection Blocked'

[REDACTED]

Hi, got a pop up a couple of times in the last few days (attached). I don't seem to have anything in the virus quarantine chest related to this problem.

What the heck is it, and what should I do next? Thanks!

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

Hi, please find all the scan logs attached. Cheers!

Actually, I made an odd observation: I only get the 'infection blocked' popup warning when I decide to go to my Yahoo email spam folder. I don't think I've ever clicked on any of the spam emails themselves or opened any unusual email attachments before, so why I'd get it when I simply click on the spam folder is beyond my limited comprehension! I just tried it a several times just now and it seems to be the sole culprit. The url is different than the one I had previously, so I'll include a screen grab of it in my next post (I can't include more than 4 attachments per post on this forum it seems).

And here's the screen grab of today's warning.

OK, now you've to wait a bit...

Do you have Chrome open when you get the alerts ?

Yes, this occurs when I go into yahoo mail via Chrome.

Noticed flv player was deleted ... ouch, been using it for years.

Should I try and go into my yahoo mail spam folder and see if I get the same warning popup now?

There's an AdwCleaner[C1].txt, assume you don't need that?

And FRST left a MBR.dat on my desktop. Do you need it or is it a temp file that can be deleted?

[essexboy]

Hmm not sure why that was deleted .. I will ask.

OK next time you go to yahoo use IE or Firefox, if you get the same alert then Yahoo has been done again

[REDACTED]

Just tried going to yahoo's spambox via Firefox, and it happened again. I got another screengrab attached. 

Just noticed the first captured image seems to relate to a spam email from 'Louise'. The second image relates to a later spam email from 'Ingrid.'

How much of a security risk is this problem?

Thanks.

And FRST left a MBR.dat on my desktop. Do you need it or is it a temp file that can be deleted?

It will be gone when Essexboy remove tools used   

[essexboy]

Clear your spam folder and then see if the alerts cease

[REDACTED]

Deleted all the spam, and now there's no more warnings from Avast when I exit then re-enter the spam box.

[essexboy]

Any further problems ?

It seems as though one of the spam e-mails was trying to phone home to tell them that your mail was a live one

[REDACTED]

As of this morning I've received no new spam (so the spam folder is empty), and when I enter the spam folder I receive no warnings. Phew.

[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
