that is NOT from microsoft it is one of the rogue fake antivirus infections. You never want to click on anything one of those pops up and definetely never give them money or your credit card that is what they want. What you are seeing when it shows those infections is not really your computer at all it is simply a picture they are showing you everyone sees the same exact thing you are being scammed.

I had something similar for 89.95 and 99.95. There was no way to close it and all my buttons on the desktop were gone while this was up. Every time I clicked on something it would direct me to the pay up site.

I wound up doing a hard shutoff and going in safe mode and then resetting the computer to an earlier check point date by two days before this showed up. Now it's gone.

I think it said PCDefender, real nasty stuff.

Good advice on the two posts while I was typing, but, there is no way to download or run anything till this thing is gone. It blocks the whole computer.

Well we should get the user to Malware forum if that turns out to be the case. Right now lets see if it will run..

IE is susceptible to a lot of these (some very convincing I must admit) exploits, which is why I recoomend Opera or alternate browser, or the tightening up of IE configuration settings.
Try resetting IE to default (Tools, internet options, advanced, reset, assuming IE 8 which I hope everyone has by now.)
One thing I explain to clients which brings home the point, is "how long does your antivirus take to scan your pc?" The answer of course is in the "long time" category. My next question is, "so how does any alleged software claim to tell you your machine is infected with many, multiple exploits, immediately you visit aweb page?"
Point taken.

hendricus doing what you did does not fully remove the infection from the computer, in those cases it is highly recommended to go to one of the malware removal forums for help with cleaning the system.

It would be a very good idea for you to go there and run a few of the scans they will suggest to make sure your pc is not still infected.

much better to be safe than sorry, you do need to register then begin your own thread in the area I linked to.

I have Malwarebytes on my computer and run it frequently, evidentally not often enough. It won't open now. I tried to download it again @ cnet and download.com and it wouldn't save to my computer like it should.

Went to IE and I get to Google to find the download sites and get a warning: IE is infected with the same song and dance routine.

Help! I'm getting scared now.

Forget to mention I use Firefox as my browser.

Gale you will need to go to the forum I mentioned above and register then start a thread there in that same area I am linking you to. Tell them what happened just like you did here and you will get assistance, you will be led step by step through the process.
Analysis and Malware Removal
go there, register, post a thread in that area.
Then please follow the directions from that forum so there are no miss-communications. I will watch for you there, let me know if you need any help posting.

I'm no computer expert but just curious if you have tried doing a system restore to an earlier time? Sometimes in the past that has helped me with pc issues. My girfriends Dad had the exact same thing on his PC this past weekend and he has no virus protection at all but did have Windows Defender on & it was hidden behind the rogue pop ups & once I clicked them out then I hit remove on Windows Defender and it was gone. Actually I was surprised it was that easy. Good luck I know how frustrating these issues can be. There are some smart folks that should be able to help you out on this board.

ravencajun, I can't get the anti-bot question right. Duh!

I forgot to thank each of you for your time & expertise. I really do appreciate it.

It really is not that easy, those infections often leave behind rootkits and other nasty stuff when tried to remove that way, which is why it is extremely important to go to one of the specialty forums that deal with exactly that type of infection and get them to help run some scans with tools that can find those left behind nasties.
Many of these rogues now come with a rootkit, the recent problem with the MS update which caused many people to have an unbootable pc was because some of them unknowingly had one of those rootkits hidden in their pc.

ravencajun,

Better send to landz.forum.

Just try it again ask for another one, take your time. I tell you what I will go ahead to the area I linked to and start the thread for you so just look for a thread with your name in it ok.

Worth a shot if the exploit isn't overly sophisticated. Caveat, many exploits can and do reside in system restore.

zep, I'm trying to get to the landz forum, but can't get the anti-bot question right when trying to register there.

OK, thanks. I'll head over there.

Gale here is the direct link to your thread.
Thread for Gale_Tx

just copy and type what it shows for the question you are having problems with.

RC, Not sure what you mean by copy and type what it shows for the question you're having problems with. I can't register, so, I can't reply to the thread. I feel like such a dunce.

I'll keep watching the thread and perusing the loads of info they have there.

On the anti-bot question: What's the code? The color that matches its name is Orange, right? Number of letters that's repeated in the recording is 5, right? Sorry if I shouldn't be mentioning this here, but I know it's simple. I guess I'm even more simple because I can't figure it out.

Hi, Gale.

I know the anti-bot measures are difficult. They give me problems too. :) Note that they are all letters, no numbers included. As ravencajun indicated, keep clicking the "Request another image" link until you can read the letters. You can also download a wav file to hear the letters.

Hi, Corrine! Tks for stopping by. I can read the letters without a problem. The anti-bot measures question is what's giving me fits. I've heard the letters, read the letters, typed them in all correctly, I assume. When I accept the terms, etc. and click 'register', it tells me my antibot question is wrong. Grrrrrr!

It's your texas accent maybe. I hate those things too.. I'm forever clicking to get a group I can read. Then it says your page has times out when I click submit. Re-enter and confirm your password.. I get so angry I forget my password and say two simple words before closing the browser window - and they are not 'bless it.

Gale,

There is a second anti-bot measure below the letters. It will either be a math question (What is the sum of...) or a word question (Which word matches its color where a bunch of color names are listed but only one name matches).

Tks a lot, Corrine! Not sure what I did differently, but, I DID IT! Be afraid, be very afraid, lol.

That did it! She made it. :)

woo hoo way to go Gale! Thanks Corrine!!
You are now in excellent hands at LzD Gale.

Since I've reset the computer to an earlier time than the virus I've run Malware, AVG, Spybot and CCleaner and nothing shows as infections or problems. Hopefully the problem is gone and gonna stay gone.

Been good for two days now.

It's definitely a SCAM!

I get that pop-up on my computer and it claims to fine a gazillion Windows viruses ... when I am running Linux!
