It happened again!  Malware ate my shorts. 

 

I definitely try to be safe online and yet it happens.

 

Are there ways to physically prevent an outside program from altering my browser settings?  Anyway to password protect those changes?  Is there any scanning software that would identify the malware before installation?

Accidental installing of programs or software can cause such.

 

My Antivirus KIS (Kaspersky Internet Security) gave me an option of not installing any additional unnecessary programs by installers while its setup. That usually lessens my burden while I run any installations.

 

Use an Adblocker and don't click on anything that they offer for you free.

 is my suggestion.

 

Run updated internet security programs. Keep your windows uptodate is another word.

 

BTW you can always scan an installation program before installing just to be safe.

If it is not very huge check at virus total for its report by various scan engines. here : https://www.virustotal.com/

I am talking more about actual physical actions I can take.  After I posted I poked around online and one site suggested changing the DNS setting from the default to two rows of numbers, I think 8-8-8-8 and 8-8-4-4.  I use Firefox and Chrome.  Is there a way to lock those so these kind of alterations are not possible, or I suppose the browsers have to be able to alter settings to update and function properly.  That's what I'm looking for.

 

Thanks for the info.

Those DNS settings (8.8.8.8 and 8.8.4.4) are Google's public DNS servers that anyone can use, and changing DNS settings is a troubleshooting step for certain kinds of issues.

 

Public DNS servers -

I would recommend uBlock Origin for Firefox and Chrome...it's more like a "firewall for a browser" than an ad blocker (it does that also), and uses less resources than AdBlock.

Thanks.  I'll check out uBlock and I read the articles.  I try to be safe online but after reading the article, I realize that I have to be more aggressive about updating software.  I mostly use Firefox and have added NoScript and ABP for years.  NoScript is annoying but that didn't stop me from using it.  I am vigilant about most of what Krebs outlined in his three rules, but obviously not enough.  I sure do have a knack for finding browser hijackers.  Thanks again.

There is software that prevents adware, and browser hijackers just before installation. It's called unchecky.

An adblocker would not prevent the installation of browser hijackers. It might block ads that promote adware, but this should already be done by the advertiser network...I said SHOULD lol.

Just watch what you install. I don't think anything is as good as being careful at the end of the day these type of things are normally installed with free software so read each step as you are installing things and review what your about to install by using a simple google search on it to reveal any of it's hidden dark sides. So you are the best tool to be honest.

You could try avast they claim to have a good antihijack tool built into the antivirus

https://www.avast.com/c-browser-hijacker

 

From memory I think Malwarebytes antimalware also blocks on installation some of these things but only the full version will do it real time.

 

You are the best defence being vigilant and reviewing what you install before you do so. A little effort can often save a lot of pain.

 

A good tool to use if you do get something browser related  is junk ware remover

https://www.malwarebytes.com/junkwareremovaltool/

 

MVP Hosts blocks some hijackers from conecting but will need to be checked from time to time for updates

Thanks.  I'll check out Unchecky.  I found some comments in forums suggesting it might not be that safe itself. 

 

I got a nasty PUP from sourceforge while downloading Filezilla.  That was a while ago.  I may have been hasty and didn't check custom install.  But now I do. 

 

One thing I've learned about browser hijackers, for me, at least, is not to waste the valuable time of moderators here trying to help because I have never successfully cleaned my computer after a hijacker invasion and end up reinstalling the OS anyway. 

 

My computer repair man suggested getting MalwareBytes pro as it offers real time protection.  I've certainly used Malwarebytes enough times and don't mind supporting them, to boot.

 

Thanks.

 

Since then I always seek out the developer's download.

why not post in the malware section if you still have an infection and let some one clean it for you.

 

To help stop browser infections use an array of tools to layer your defence I will list a random few.

Avira browser safety. Gives green ticks while surfing for safe and red for bad. (Might not need depending on which anti virus you use)

MVP Hosts file. Will block an array of things including what you need.

Spywareblaster. Will block browser hijackers, adware ect.

Mbam is good but has to be the full version to be able to catch things in real time.

This will not be bullet proof but will give you better browser protection but it would be wise to get cleaned up first.
