anybody can recommend a good anti virus program for my pc?

Use Avast Home edition which is free; it updates frequently.

Norton Anti Virus and Mcaffee

Sounds like you need more than a AV program now. I have provided a link that will walk you through disinfecting your computer. The link is free. The site is free. The help is free. Hell even the software they recommend is free.

Whats not to like.

AVG anti virus

AVG Anti-Virus... although I doubt it will help your pop-up situation... that's usually caused by spyware/adware.

if you are having trouble choosing light weight anti-virus program, just go for antivir personal classic edition.. its free ware... you can download it from http://www.free-av.com/

if u want pop up blocker then just use any of the yahoo/google/msn toolbar...each of them has pop up blocker.

Try Bitdefender. You can download it at www.bitdefender.com

It has antivirus, firewall, antispyware and antispam all in one.

There is FREE 30-day trial version. I'm using it myself. It rocks!

Use an antispyware. You can download Microsofts antispyware from http://www.microsoft.com/athome/security/spyware/s...

I use Norton. You could try AVG, it's free
