Title: Keep getting web-infection blocked notifications
Post by: REDACTED on December 15, 2014, 06:24:02 PM
Starting today, I've gotten 3 notifications about web-infections being blocked.
What's going on? I'm not even visiting fishy websites.

Welcome to the forum.
Remember that today's good site can be tomorrows infected site.
You can always report the website to Avast if you think the detection is incorrect.
If you'd like someone to look into the problem further, you can post the link that's detected here
but do not make it a clickable link, Change http to hxxp or www to wxx when you post the link.

It happened on 3 websites in one day, and it usually never happens.

If you can also attach a screen of the avast alert window, it will give more of an idea of what the detection is.

If it has happened today and you haven't rebooted or had a different avast popup, then you can right click the avast tray icon and select 'Show last popup message'.

It looks like some advertising banner add is going to a site considered malicious (URL:Mal) by avast. This usually means that the site is on some block list. Presumably you were at another site that displays ads.

Is this basebanner.com reflected in the other alerts that you have had ?

This could be a form of ads poisoning is becoming more frequent.

I use the firefox adblockplus add-on, so generally I don't see these ads and subsequently avast alerts if an ad site is compromised.

Yeah, site had ads.

It is difficult to say if this is a random case of ads-poisoning or if there happens to be something in your browser trying to connect to malicious/hacked sites.

This will probably need the skills of one of the malware removal specialists, I will try to get one to take a look at this and they will advise on what the next stage is.

Site is unsafe and has privacy issues...as Para-Noid has already clearly established.
Some additional info to get that picture somewhat more complete and where the real issue lies is a "http - https redirect"
basebanner com is trying to redirect to basebanner dot com/blank.html
Flagged by Bitdefender TrafficLight as malicious.
Google Safebrowsing does not flag now: http://www.google.com/safebrowsing/diagnostic?site=basebanner.com
Did not follow redirect to http://158.85.47.164-static.reverse.softlayer.com/blank.html
The plain HTTP request was sent to HTTPS port  SSL teracreative dot com -
Had a history of trojans: http://google.cn/safebrowsing/diagnostic?site=teracreative.com/
The specified URL does a non search engine friendly redirect to another page....(24 pages do a 302 (temp) redirect.
Nameserver issues: http://www.dnsinspect.com/basebanner.com/1418694696
The https site has privacy issues: http://www.uploady.com/#!/download/xhL_JQbJSQT/VyjzWt~mABywNd9w
Net_err_cert_common_mame_invalid - only correct autocomplete settings - Form element of type 'url', child of <form> '_f'

Personally I would take essexboy up on his offer (if you are still having problems) to run some analysis tools to see what is what.

It could be ad poisoning but if you are still having problems I could take a look for you

MalwareBytes may not be enough for a detailed analysis. After you have attached that log, check out this topic "Logs to assist in cleaning malware" https://forum.avast.com/index.php?topic=53253.0 (https://forum.avast.com/index.php?topic=53253.0) and run the next tool Farbar Recovery Scan Tool (FRST) and attach the log in this topic. Then wait for essexboy to check out the logs and give further instructions.

How would I get essexboy to take a look?
(I'm only 16, I'm the only guy in the family who cares about computer safety). And I'm quite nervous about getting someone else in another country to take a look at my computer.

Post by: Michael (alan1998) on December 16, 2014, 05:42:28 PM
Just some scans. They do not release any private info unless your Username contains your Actual Name.

In most cases posting here releases more info as (some (Ubers, Mods/Admins/Avast! Team) can see your IP)...

If you wish, I can post the same logs from one of my system(s). You can get the tools from this site: https://forum.avast.com/index.php?topic=53253.0

You'll also notice if you visit the V&W section, Essexboy leads most of the cases, and most are usually resolved unless there is a hardware issue. I've trusted him before and he has never not once let me down.

(You can also find him on a bunch of other sites like geekstogo.com/forum/
Title: Re: Keep getting web-infection blocked notifications
Post by: REDACTED on December 16, 2014, 05:45:31 PM
Well, it's 17:44 here atm. I could let him do the scans tomorrow, but he would have to be able to do them before 16:00 my time.

Tom you need to do the scans from the link above and provide/attach the logs for essexboy to look over when he is available and if there is an issue he can provide a fix.

You have already run Malwarebytes so you only need to run Farbar as DavidR mentioned on the previous page.

Please calm down. Anything essexboy suggests/directs you to do is for your benefit.
He will never, ever ask you to do something which could/would compromise you or your
system. Just post the logs as requested and he will take it from there. You will be in the
safest hands possible. And he has endless patience so don't be afraid to ask him any
question if you are not sure of anything.

I have notified essexboy so post your logs as requested.

Generally there is no personally identifiable items on the scans it is just a list of registry loading points, programmes installed etc..  After I have looked at them you can delete them from your post.  None of the bots look inside attachments either :)

Hi tom.vanhee,

No one is going to look inside your family's  computer, the qualified expert just will go over the scan logs you are asked to produce here and then come up with a removal script just for you to cleanse the family computer. The people that are allowed to do that here have an online outbuilding that is recognized by sites as MS and others online.
You could not be in more secure hands then those of a qualified removal expert here. For demanded logs see: https://forum.avast.com/index.php?topic=53253.0

Okay, I'll do it tomorrow afternoon (live in Belgium, so you guys have an idea of what time I'll post them).

If you are "not sure" that's the best reason to accept essexboy's help.
After he's done then you will be sure. Until you post the MBAM and FRST
logs no one is sure.

Look at it this way, if there is or is not an infection I'm pretty sure your parents
will be grateful to have an infection free computer.

He will give you step by step instructions as he goes. If, for any reason, you are not sure
about something don't hesitate to ask him. essexboy has helped tens of thousands of others

Hi tom.vanhee,

This malware routine will only be healthy for that family machine, whenever the problem persists I as one would not hesitate to risk it.
As attached those logs cannot be seen apart from those that have an account here and are logged in. As said later you can remove them, no sweat.
There a lot of things you are not allowed to do when 16 years old even in good old Belgum, but being helped to cleanse a computer from an online infection is no big thing. We have a person here who when 15 years old scanned infested website code and now at your age is a  voluntary website analyzer.
Everyone knows who that person is and he is very, very smart, a reel g33k and I have very much respect for what he does.
I am 66 and even I at my respectable age am very much interested to learn new tricks and sometimes also feel the drive of an "inspired teenager" to try new roads of exploring. In Holland zeggen we: "Heb geen watervrees!".

We are now on page two and nothing has been accomplished.
Help is freely offered but must be accepted by the person seeking help.
Begging isn't something that needs or should be done. IMHO
The same service offered here by qualified helpers is also available at some of the
better computer repair shops.
The difference is that the service is Free Here and can cost you a fortune at the shop.
