Antivir Pro is a virus

I've been using the free antivir basic for 3-4 yrs without a problem, everyday antivir has a popup message at about the end of the day to ask if I want to upgrade to antivir pro (pay them $49 I think), I clicked on NO everytime, of course, lol.  Last night, I came to LCB to download Aladin Gold casino, everything went fine. About 5 min after I finished downloading, booom, virus attacked.  I couldn't do nothing, couldnt get on internet, couldnt use the command in control pannel to restore system,...everything was blocked by the virus = anitivir pro, and it kept direct me to antivir pro website to buy their program.  I aint stupid, I know antivir pro is a virus right away, why?  lol, couple yrs ago, I had virus on my other old laptop, there was an automatic anti virus asked me to buy their software because virus infected my computer, bla bla bla, I didnt know it back then, felt for their trap, couldnt solve the problem and ended up threw my old laptop to the trash can, haha. 
I've been trying to fix my laptop the whole day today.  I went to Office Max tech and they want me to pay a minimum price of $170 to fix it, hell no, I saw a new laptop price as low as $280, why should I pay that much to fix this virus thing.  I went home, read ad in new paper and finally found someone who can fix for me with the price of $55, no need to do format, I dont know what he did, he will not share if I ask anyway, it's their secret to make money.  Anyway, I went to casino nearby while waiting to get my laptop fix (havent gone to local casino for a year), I had $300 in my pocket, played really small on slots, trying to kill the time, yet I lost almost all of my money in couple hrs.  I had a ticket with $8 left, went to  the machine, forgot what it calls, but I kept hitting free spins, won up to $520, then dropped to $450, then decided to cash out  .
