Generally, an AntiVirus is a program that scans the computer's hard drive for similar behaviors, per say, of viruses and such.
i want a anti virus that can protect my computer much better
Definitely, one of the best AVs currently on the market is AVG.
Also, it's free.
However, the best way to avoid viruses and such is not just a single AV. Rather, it's the combination of several antispyware programs, along with BEING SMART on the internet--no stupid downloads and such.
Also, realize I said several antispyware programs, not AVs. Running multiple AVs can easily result in a computer crash. In other words, don't do it :)
(aka hard to find a DL of it online if you wanna go non legit)
Lastly, please don't cheat the companies that help us in the battle against malware. They're the ones helping us.

Though for all those that do want a QUICK way to get rid of a virus go for "AVAST!" *actual title of the software* it has a free 30 day trial if you want to clean up your computer, though per the quote above, then please spend the 20 - 500 dollars to get the legit program, dont hurt those that want to go legit.
