if you ask me 99% of all antivirus products behave like virus's and spyware these days - take norton for example (installed on more then half of new laptops):
* It asks to be updated
* It slows your system down
* It asks you to pay some money for "renewal"
* It bugs you and drives you mad
Doesnt that sounds more like spyware and virus's? Whats the difference??
I agree with shieldhead, and i dont bother with a/v products, id rather 100% performance and a small risk (well thats actually BS i never get virus's - awareness is the best protection from virus's/spyware etc) of getting a virus then crap performance and some lame product telling me im safe when in reality its the same just a slower system.
Products like AVG are rubbish, scanning every day, for WHAT? something it missed WHEN ITS BEEN RUNNING THE WHOLE TIME? Do they not trust there own product to pick something the first time?
Avast is more like a stupid toy i dont need sounds and colour on my a/v product and some bs GUI - same goes for norton, trend etc
Trend's new TITANIUM product on 50% of the systems its on doesnt want to install ( mostly crappy XP's problem) or it just quits randomly for no reason - great product that is.
Kaspersky.... seems to work ok, then again to activate it is too much for a customer to handle rather then entering a simple key to use the product
Malware bytes and spybot, spyware blaster, superantispyware comeon one antivirus/security product on your system is enough, when theres 2+ its just stupid - dont even bother
Its all gay, seriously get educated about what to avoid and you will be fine, get some experience.
