Best/fastest anti-virus for Vista use?

I used to use Kaspersky but it was giving me problems with Steam apps so I uninstalled it and replaced with Avast, which works very well and silently in the background. very nice especially since it's free.

 

I think I might go with Kaspersky. If I were to buy the Kaspersky suite, that'd have me covered right? Antivirus/spyware/adware, and everything? And it runs real fast and doesnt bog down system resources?

 

does anyone else feel that avast uses more resources and slows ure comp down more than avg?

 

@eyecon82:

It's been a while since I've used a system that DOESN'T have Avast on it, but I've not found it to be a resource hog.

 

I have Avast and i have not had a virus/trojans etc...for over 2 years now and I feel no slow down in performance at all. And I use a pentium M 1.8ghz laptop.

 

I honestly don't usa an antivirus program. I run the Kaspersky online virus scanner regularly though. It's free, and it found some stuff that AVG never did.

 

anti virus only programs though dont protect against spyware n stuff does it?

 

what do you guys think is the best anti-ad program? i use ad aware for a weekly scan; but what is best to prevent these programs from even downloading on our system? thanks..i may switch to avast from avg; i have had no problems and i switched back for a few days to avast and noticed way more hd activity than with avg

 

@eyecon82:

I suggest Spybot to prevent infection from spy/adware. As long as you keep it up to date and use the immunize feature regularly, you should be as safe as an application can make you.

 

The company I work for installs F-Secure Suite on all desktops and laptops. I have been using my company issued laptop with F-Secure for the past 3 1/2 years and have NEVER had any Spyware, Worms, Trojans, Rootkits, Malware or Viruses. I started using F-Secure on my home computers about a year and a half ago and have not had any issues since. It doesn't seem to use alot of system resources either. F-Secure isn't exactly cheap at $60 US but it is an all in one package that includes A/V, anti-spyware, firewall, spamblocker, and parental controls. For me it's been way worth the money...
