using Windows 7 and got a virus that hijacks my Firefox browser.

Virus Name is "Diagnostic-com.com"

There are virus removal tools like SpyHunter that scans and detects problems for free but you have to purchase it for removal.

Any free tools that will remove it?

Try Malware Byttes and Super Antispyware. Those tools can help find where these malicious viruses are hidden away in your registry files. Annoying little buggers, got them trying to live stream tennis.

Launched in safe mode, Malwarebytes and AdwCleaner should remove most malware. If it's a virus, well generally it's a bit late and you need someone else to give your HDD to clean up because viruses tend not to allow you to clean by yourself. But you're better off going to a specialized forum really.

I use Microsoft Security Essential as it is free on Windows 7 and Windows 8. I have also used their malware scanner and I run MalwareBytes scans from time to time. I think that Avast is a good freeware product but you do have to re-register annually.

A browser hijack might be different. If I had something that hijacked Firefox but not Chrome or Safari, I'd try to fix the browser installation or the Mozilla Profile. You might see if this problem has been seen in MozillaZine (Mozilla support forums).

gosh, i've forgotten about those troubles.

got a mac 5 years ago and haven't had an issue since.

maybe i'm lucky but i don't worry about where i surf, stream etc anymore. i figured eventually it would catch up to me bbut it hasn't yet.

the above suggestions ring a bell from my pc days.

good luck, hate those dang viruses and the d-bags that produce them.

Malwarebytes is great to check your system.

Also Avast has a free and good anti-virus program.

:grin:

I got a horrid virus a few years ago that mimicked Avira (which was a dead give away because I was using AVG at the time) and shut down all my virus protection software. Used my other computer to get instructions on removal and was able to clean it up using free programs.

1. Instal rKill. Fantastic little program, every PC should have it.
2. MalwareBytes. Another good program. Gets great ratings from all kind of magazines and website, does not install junk on your computer.

Those two programs in safe mode got rid of the worst of the problem, then I ran whatever the Windows free online tool at the time was, and something else that I don't remember (spy something or other). Took me about two days of full scans and rescans, but that virus was gone for good. Then I uninstalled AVG and switched to Avira free because it turned out to be a better program. I also added CCleaner as a registry cleaner. Run all those once a month and my PC works about as well as could be expected.

Once you run rKill and MalwareBytes in safe mode to isolate it, use whatever online tools Windows has for 7 to isolate and remove it. Good luck.

Best anti virus in two steps:
1. Reformat your hard drive
2. Install Linux distribution of your choice.

Thanks for the replies. Will probably try Malwarebytes...

I always browse with Firefox but I launched Chrome to see if it was infected too. And it was.


Would another option be to just do a Windows System Restore? I think I just got the virus today so maybe restoring to a recent state will fix it.

But dont know if Windows System Restore will fix the bad Windows registry entries the virus installed.

The WebDiagnosis.com pop-up malware is an annoying application that comes uninvited and silently gets attached with web browsers.


It targets Mozilla firefox, Chrome, Internet explorer etc on all windows operating system.

If unluckily your browser is hijacked by WebDiagnosis.com virus, you will be getting unwanted content popping up on your screen. Actually the WebDiagnosis.com popups are filled with paid advertisements that are linked to third-party websites.

Does doing a Windows System Restore to a recent good state put the Registry back into a good condition?

Alternately, if you need a Windows desktop, install VirtualBox and then your favorite version of Linux in a virtual machine and make a local backup copy and do your web browsing in the virtual machine.

Or get a Mac. There's some amount of system management on Linux that some may not want to do and it's generally easier on system management with a Mac. I use all three of these platforms (and a few others like VMS, HP-UX, etc.) at work.

Yes it does. It restores everything to the previous state, including the registry.

This being said, why not try one of the tools people above recommended, first.

Yes VMs are long term way to go. I would actually do the other way around and install Linux and than Windows in a VM if really needed, using VirtualBox, VMware Player, or KVM.

Mac Books are nice if you are willing to shell out extra money.

Create a Standard User login on Windows and use that for surfing. Only use the Administrator account to make changes to Windows. The Standard User cannot install most software without an Admin password. That at least gives you a clue that something nefarious is trying to plant itself on your hard drive.

Never used Linux before. I may try it.

I use the PC mainly for browsing.

Is the browsing experience pretty much transparent (YouTube videos, sound, etc?)

Does Firefox run on Linux?

Plugins and extensions can be a little harder to setup for Firefox on Linux but most stuff should work.

Firefox definitely works on Linux. Many distros come with it pre-installed.

I run a Linux VMs on a Windows desktop. I also maintain a backup VM. If something happens to the Linux VM, I just delete it and copy from my backup. The VM is basically a few files in a directory.

I do the same thing with Windows VMs. I have a Windows VM on my Mac. If something happens to it, I can just delete it and copy it from backup.

The best free Windows removal program may be Linux.
I have heard people discussing this. Whether the relative lack of viruses on the Mac and Unix/Linux is due to:

1. The OS is superior and less hackable.

OR

2. Hackers don't want to bother writing viruses for OS's with less than 10% of the market share. :smile:
