You most likely have Vundo/Virtumonde. It’s hell to get rid of. I tried a whole lot of stuff on a friend’s computer and finally gave up and reformatted. Then another friend got it. I tried a few more things and finally found one that works.
Malwarebytes’ Anti-Malware can be had for FREE from CNET.com.
It removed Vundo! Glory be! You have to run it in safe mode to get it to remove the files that reinstall the program every time you reboot.
Don’t spend any money and happy new year.
Highly recommended.
Excellent free software.
Sounds like Anitvirus 2009. My dh just got it off his computer using Malwarebytes. Av 2009 caused the computer to do some squirrly stuff too.
And scans with virus/spamware programs (for instance McAfee & AdAware) could not get rid of it.
We got our version of Malwarebyts as well as advice from BleepingComputer.com. But there are other places out there.
Malwarebytes downloaded but wouldn’t start up. Our problem was that this virus seems to recoginize the program and “prohibited” it from running.
As was suggested we had to rename it and then run it. It worked but it took 3 or more scans till it was all gone.
