Hi, for paid version, you could try Kaspersky Antivirus. For free version, you could try Avira. Currently, I am using one of the free AV products which is Avira AntiVir Personal Classic Edition. Since using this one, I have no problems at all and I am very much satisfied when using this one. It updates regularly and you could schedule it at your most convenient time. It is very light on resources and does not eat a lot of memory. It does not slow down your computer. Its primary function and advantages is to provide protection against viruses, worms, and trojans, protection against dialers and phishing, and detects and delete rootkits. More than 15 million users worldwide trust in the reliable protection of Avira AntiVir, and this is no coincidence at all. It has gained several awards. The product combines first-class detection rates and ease of use with a top performance that protects your computer safely. You can download this at www.free-av.com.

In my opinion, the best anti virus program is AVG. I've been using it on all of my computers for over 3 years and I haven't had a problem with any one of them since I installed it. The best part is, it's free! You can download AVG Free here http://free.grisoft.com/doc/5390/us/frt/0?prd=aff I hope this is helpful for you.
