My father got a virus three weeks ago that acted as you described, O2BDumb, and I can pretty defininitely tell you your computer is already infected and will not even be able to access malwarebytes’ website or any other helpful one. Also, I would predict if you try your System Restore you will find it disabled.
I agree with the suggestions given in previous posts. I successfully removed this virus (mine was called Perfect Defender 2009) just in the last few days. Trouble is, I would never have been savvy enough to put the previous posts’ suggestions into practice without help.
By the way, I had the bogus Google pages you mention too, and I was foolish enough to actually download the “fix” the virus wants you to download. That is when the virus really got ferocious. But whether or not you have done that, you are already infected.
My solution was to go to bleepingcomputer.com. I had to go to the site on an uninfected computer (mine) since the virus (on my father’s) would not let me go there. I had to download suggested fixes onto the uninfected computer also.
Bleepingcomputer.com is, as far as I can tell from my dealings with them over the last two weeks, just a bunch of really nice people who really hate malware and have banded together to give free step-by-step advice to get rid of viruses. They’ll deal with any computer problem, but I notice they are especially dead-serious about malware. I have presented a problem to them since my virus fix, a recalcitrant taskbar that somtimes dissappears, and they seem a little less than enamored of helping me yet with that. It’s malware they like to fight.
Removing this virus is not quick. It took me and the person assigned to my case at bleepingcomputer four days of back-and-forth posting before he (or she - they have screen names like we do here) removed the last vestige of the virus.
One thing I can recommend is stick with the program. Early on in their recommended treatment (the first day in fact) all noticeable manifestations of the virus disappeared. The expert assigned to me was unimpressed and, as it turns out, was only just beginnng his removal of the virus at that point. You have to stick with the program until the malware is fully removed. Abandoning the process the minute everything seems back to normal will result in the virus springing back to life.
After the virus is completely removed and everything is back to normal, they set you up with free malware protection program of their recommendation and help you through its setup process.
They are professional and thorough and are on some kind of internal graded rating system like apprentice, journeyman, master, etc. (although not those names exactly).
I have only praise for my expert, whose name was fenzodahl512. The machine was so sick I thought it would die and now it is completely back to normal.
