Infected with "Vista Total Security 2011" malware

I have a laptop which run Windows Vista.
This afternoon, One software named"Vista Total security 2011" popped up in my laptop. It scanned my laptop and stated that my laptop was infected with other Malwares. It look like the window Security program.
At first, I ignored it because my laptop run with Esset Smart security 4. It made feel that my laptop really infected and want me activate the software. Another time, it want me to purchase the program.
I did click on the "Purchase" button of the program.
At that time, I cannot connect to the internet.
I tried to run Esset Smart Security 4 but failed.
The Esset Smart Security 4 just completed 55 % of process of scanning.
It stay for many hours but can not go any further.
Please give me any advice and any help on this problem.

Thank you very much for any advice and your help.

Does Eset not have signatures for this?

 

You have just fuxored your computer my friend. Eset is there to protect you, but it can't help it if users throw themselves into a pithole with fire inside it

It was very obvious that this is a trick to lure you into to clicking on that ad or installing something.

What I would do if I were you? Quickly backup my info on some external HDD (only docs, pics, videos) then format and start fresh again as you never know what it might have infected.

Good luck, and don't click on anything that shines in the future

 

I had a similar problem on an XP system. It was very bizarre: icons on the start menu vanished, there were continuous notices advising me that my system was being destroyed, I couldn't use either Firefox or IE. I think it called itself a MS Security Upgrade. The icon style of the 'program' was Windows 7 which was a strong clue that this might not really be a MS product.

I didn't click on it, and I got rid of it by using System Restore.
