Is there any method of full security for computer against viruses for windows

Thanks man for selecting this topic for The BEST response.. It always feels good if you get best response ! Adding you as a friend !

I am using ZoneAlarm, but then also one spyware had got installed on my PC.I removed it.So I am searching for more secure solution.

See dude !! . I used Zone alarm .. but it kinda slowed down my PC .. So I switched to Ez etrust CA antivirus .. If you want I can give it you .. You need to understand .. that Virus and Spyware are two different things .. For complete spyware protection switch to Xoft spy .. www.paretologic.com .. Hope this helps !

Thanks for the information.But I was in search of some software which will restrict any unknown script to be run on my pc.I think it will enshure near to 100% security.What do you think.

Thanks for the information.But once I had installed one instant recovery software.But my PC got attacked with one such virus which cleaned my partition, thus all data was lost amd my PC was like a new on with blank harddisk.So what can we do with such viruses.

Ouch! That's seriously hurt, to have your drive wiped out. I've heard of viruses that blast the MBR, but I've never seen an instance of it myself. Most of today's malware consist of mutated Trojans. Actually, they're part worm, part Trojan, part virus, and sometimes part rootkit. There are still traditional viruses out there, designed purely out of hate or desire to "turn heads." But most threats are designed not with the intention of destroying your machine completely, but gaining control of it and using it to make money. Most of today's blended attacks will overwrite files in your system32 folder. When they do this, System Restore is foiled. Restore points keep track of the index and settings; they don't do anything about the actual binary data which comprises the files. You need a dedicated drive imaging program for that (I use Acronis). The key is proactive security, rather than reactive. You can't afford to get hit so much as one time these days. At minimum, you need a firewall that includes IPS (Intrusion Prevention Systems). As you might know, most of the attacks you run into these days are drive-by attacks, which will probably continue to grow in prevalence since web rating tools like SiteAdvisor (and Cloudmark, once upon a time) are doing such a good job at steering more and more people away from fraudulent sites. A few firewalls I trust for defense against most online exploits are BlackICE, Kerio, and AOL (I find McAfee Personal Firewall Express much less "constrictive" than Personal Firewall Plus). There are others, I'm sure, but these are the only ones that have stood up to everything I've encountered. And although I haven't actually witnessed ZoneAlarm Pro fall to attack personally, two of my friends did call me to save their machines back in October when SQL Slammer and StackBot brought an estimated 11% of the world's computers to their knees with IRC Flood. Beyond your IPS firewall, how much more defense you need depends on what you do online. I don't download much these days, but I've found that I tend to mess around much less when I put up enough shields to make it an inconvenience. Arovax Shield automatically blocks changes to the registry and system settings, while Folder Guard locks the system32 folder to ROM. I can disable them if I really want to install something, but it's a bit of a pain to go through all the motions. If you're a download junkie, but you're unsure of some of the things you download, you might want to use a sandbox or virtualization program. One of the best is DefenseWall, which includes a HIPS unit. But if you don't want to pay money, you might go with Sandboxie instead. Hope this helps!

Thanks for the guidance for securing PC.I am following these.

But without using the accessories how can a person work?

That's a very valid question. Unfortuantely, average Windows users really can't do much about it. That's why 90% of online Windows PCs will be compromised at least once, and usually much more than once. This is why you want a guru on your side. :) To be honest with you, AOL S&SC by itself can protect you from online exploits. The key element in this suite is the IPS (Intrusion Prevention Systems) in the McAfee firewall. If you open files on your machine that you're not sure of, however, you expose yourself to far greater risk.

wellcome santu, no one touches you because you are a PC guru. what are the steps to be taking by those of us who are nothin in terms of security issues
