Windows 7: I got a virus called "Win 7 antivirus 2012" It killed my win defender

I got a virus called "Win 7 antivirus 2012" It killed my win defender

A few days ago i got the nastiest virus on my machine i have ever seen.

It didn't slow my machine down any due to my having more cores and ram than i could ever use

But it got all executable files and redirected them to the virus.

It also new exactly were to hit my comp disabling my internet explorer\firefox killing my windows defender getting through my firewall and disabling most control panel programs.

I was able to get my comp back thanks to this website
i had to look at in on i different comp though.
Remove Win 7 Antispyware 2012 and Vista Antivirus 2012 name changing rogue (Uninstall Guide)

It saved me disabling the virus long enough too get control of my comp to resolve the problem.

But sadly the virus damaged my windows defender and it has not recovered.

I went to the windows website to download windows defender but Microsoft wont install it due to it thinking it is already installed.

It is not listed in add\remove programs.

I looked in turn windows features on or off and it was non existent there as well.

So after a long day of head banging i called it a day.

At least i got my comp back up to full speed

So if you guys have some pointers i would be appreciative :)

P.S. From my experience it was pretty complex. It knew exactly were to hit plus it posed as an anti virus program so a less experienced person would have believed it.

Hello Geek,

If you are sure you've removed all traces of the virus, follow these tutorials to see if they can fix anything: SFC /SCANNOW Command - System File Checker & Startup Repair

Might consider using this saftey scanner from MS: Microsoft Safety Scanner - Antivirus | Remove Spyware, Malware, Viruses Free

What antivirus are you using? Are you practicing safe internet browsing?

Thanks for the reply i will look into those links.

As for me i am pretty sure i got rid of the hole thing

I use very safe internet browsing habits with firewall etc etc. I just got on the internet to Google up some history about wwII and the next thing i know win 7 antivirus 2012 gets on there and starts making a mess of my comp.

As for antivirus i went with windows defender and spybot search & destroy for most of my probs but after this virus i got malwarebytes trial addition avg and a few other things. Just trying things out to see what i like :)

All my safety stuff designed by windows got ether disabled or trashed.

defender is automatically disabled (becomes obsolete) when an antivirus is installed. However, you are only ever supposed to have 1 antivirus installed at a time (Malwarebytes isn't an antivirus and is fine to be coupled with an Antivirus program). The reason is that they tend to 'get in the way' of each other and can cause even more problems, including being less effective and running over each other.

Also, you should only remove them with their uninstaller tool (can google uninstaller tool avg as an example for avg). I recommend never using AVG as it is just terrible. It alone causes its own set of issues, many of which I've had to help others fix. And can't spybot search and destroy be a bit vigorous and overpowerful? Be very careful when using it, you might delete something you'll regret.

Neither Windows Defender or Malwarebytes is an anti-virus program! Microsoft Security Essentials is an Anti-virus program and includes the properties of Windows Defender.

Thanks for all of your replies

I tried the elevated command prompt in verifyonly mode and it came up with nothing

If this helps any when i try to start windows defender i get: "The specified service does not exist as an installed service. (Error Code:0x80070424)

Meanwhile i will look into seeing if i can ether replace missing files or reinstall from the win defender on another comp

As DustSailor pointed out, if you have a worthwhile AntiVirus program installed it is disabled by design. I would try Microsoft Security Essentials - Free Antivirus for Windows to go along with Spybot and the regular MalwareBytes scan. :)

Thanks guys for all of your help i have done a little researching about windows defender and there was a similar person that got exact same virus and it killed windows defender on his as well.

I will look into Microsoft security essentials and i think i will give up on windows defender due to i got a virus on another machine today and windows defender was pretty worthless on both accounts.

P.s. WHAT IS UP WITH ALL THESE VIRUSES i have never in my life had such a problem as i have this week and i practice very safe browsing techniques. And on both instances it has been a huge battle for hours on end fighting to get my comp back.

Both viruses deleted windows shortcuts disabled programs and have been putting up one heck of a fight.

I'm sorry if i sound aggravated but wouldn't you if you recovered from one virus just to get nailed by a nastier one the next day?

Luckily for me Ive almost got virus number 2 beaten but i still have some work before i can declare complete victory.

But anyway thank you for your advice and help.

m.s.e. will probably be a good addition to my security system :)

And BE CAREFUL ON THE INTERNET these viruses have proven to be very sneaky! Even for the more advanced of security systems.
