Some sites blocked by browser?

here lately there are some sites i cannot visit, amazon for example, when i try or click on a link

Your Internet access is blocked
Firewall or antivirus software may have blocked the connection.


I have turned off antivirus, turned off firewall, still same thing. Sometimes i am able to update chrome and get it to work for a while, but it always goes back to the error. I have tried chrome, firefox, palemoon.. same results.. Right now its amazon, auto zone and a couple others. But any other sites work just fine.

I have ran a virus scan and nothing, ran malwarebytes, same thing... all clean

Any suggestions?

Browser hijacking is a pretty common aspect of malware, and depending on your particular anti-virus ('cause some just suck, plain and simple) and malware protection (same thing, some just suck, and I'm not a fan of MWB at all, never have been) so you might consider using some different anti-virus (at least temporarily) and malware detection. For anti-virus checking I personally would suggest doing these two first and then seeing if they find any issues:

https://www.eset.com/my/online-scanner-popup/ - this is the Eset NOD32 online anti-virus scanner which means you download the .exe file (it's safe, really, and it runs on demand aka you run it manually and it will clean up after itself when it's done, it doesn't install anything) and run it, it will do all sorts of checks on itself to verify it's clean then it will grab the very latest anti-virus signatures/etc and then offer to do a system scan (full is usually the recommendation)

https://www.trendmicro.com/en_us/forHome/products/housecall.html - similar to the one above, the TrendMicro HouseCall online scanner will execute on demand the same way (manual use, cleans up after itself when complete), offer to do a system scan (again, full is recommended) and then provide results

After those, if nothing is detected (possible but unlikely) then I'd suggest running HitMan Pro:

https://www.hitmanpro.com/en-us/downloads.aspx - HitMan Pro is another on demand tool but it's designed to detect malware more than virus activity and it does a more thorough scan of the Windows Registry which is where most browser hijacking takes place (hence having the same problems across multiple browsers on the same machine) - when you run it you'll get the "Buy Now" button but it can be used on demand so, there's no cost to do the on demand scan, just for the record, it will actually get to a screen where you select the option "No, I only want to perform a one-time scan to check this computer" so make sure to look for and select that option

There's no guarantee that anything will fix the issue(s) you're having but in my own experience of tracking down issues with browser hijacking those 3 tools have always resolved the issues for clients I've worked with. Take whatever recommended actions the scanners offer but before you absolutely commit to the recommendations make sure you read everything they provide in terms of information, files that may be infected, whether or not you want them submitted for further scanning, etc.

See if those get you anywhere.

giving them all a try now.. thanks for the tips

Tried all of the above and still having problems, seems to be getting to be more and more sites as well. Any other suggestions? This is happening on all browsers i have tried

I can't think of anything else to suggest except an OS reinstall which is typically the last ditch kind of thing but sometimes it's actually necessary. Once a machine is compromised there's really never ever going to be a point where it can be 100% trusted again, and if the issue is not with your ISP or network services provider then it has to be on your local machine so a wipe/reinstall might be the only option to resolve it unfortunately.

Did some research for the specific error message you're getting an happened upon a reference to this for performing a proper clean boot of the machine - the purpose is mainly to ensure that only the bare necessities are needed to get the machine up and running so any third-party software that was installed that could be involved in the problems you're having are not allowed to execute at all. If you do this clean boot process and everything works as expected then you can look into resolving it without a full wipe being necessary:
