I decided to get rid of real-time antivirus. And I'm now running my computer without any real-time anti-virus/anti-malware program installed. However, I'd like to know as to which are the good free on-demand anti-virus/anti-malware scanners available. I do not want to know about any real-time scanners, I want to know about on-demand scanners.

I already have a firewall and all I'm gonna need now is this - a good one. I hope you guys will help. :)

Ok, although they may miss some newer ones ,stopping them before they get on is the easyer way.

Look here at On line scanners

Most real-time AV programs allow you to disable real-time scanning. Is this an option for you?

IMO, not having an anti-virus working in real-time in the background defeats much of its intended purpose...to protect a computer and prevent malware infection before it can damage your system. What is your objection to having real-time protection?

Thnx. But I would prefer apps which are based on my PC for scanning. :)

Yeah, maybe that might work too. Hope you'll help. :)

They slow down my computer - now don't tell me they don't, every anti-virus software does, some to a great extent and some quite a bit. And I haven't got a single malware/virus infection in about more than the past 7-8 months. I don't feel the need. Besides, I have backups of every important thing on my computer. And I can afford to format my PC or take some efforts to clean my computer if it gets infected(which it doesn't usually). But I cannot, just cannot afford a slow PC. :wink:

That's why my personal choice is NOD32 Anti-Virus as it leaves a small footprint, meaning it is not intrusive and does not utilize a lot of system resources.

I've tried that too. But that too does slow things a bit(A very tiny bit compared to others - I agree). I'd just prefer an on-demand antivirus/antimalware solution instead. Thanks a lot BTW. You guys around here are very helpful.
:)

And please do tell me about some good on-demand anti malware/virus scanners out there. Any help is always welcome. :)

Look, what Quietman is trying to tell you very diplomatically is don't work without a net. In the wild west of today's internet, it is very foolish to not have a real time AV. By the time you catch a virus from a bad ad at a legit website, it's too late for an on demand scanner. And the bottom line is that all real time AVs slow down computers. Get over it. So don't expect a response that will satisfy you. No one here is interested in throwing you to the wolves even if that's what you want. Foolishness is not encouraged. And ignoring sound advice from Quietman is very foolish.

If I catch a virus, I don't mind taking efforts to clean up my PC - even if that means re-installing the OS. But I do mind a PC that is constantly slow. And I do not want a real time AV. What I asked for is an on-demand scanner - like, say Malwarebytes. It's been around 3 months since I've been without an AV. I scanned with Malwareybytes yesterday - no viruses detected. I know very clearly what I'm doing.

So.., if you can't help - say it. I'd happily look elsewhere. Thanks for yours and everyone else's advice BTW.

Hi Alvas,

You have repeatedly made reference to your computer being slow when you've had an antivirus program installed. Just out of curiosity...how much RAM do you have on your machine, and what brand of CPU & CPU speed do you have?

The link to the list provided by boopme in Post #2 is comprehensive and includes two of the most effective tools (Malwarebytes and SuperAntispyware) which can be used as stand-alone scanners.

Here is a list of other tools:

Actually, by slow I did not mean 'slowed to a crawl'. I meant that it was slower. It doesn't get noticed on casual web browsing or PC use. But it does get noticed(and makes a significant difference) when playing resource-heavy games like GTA IV or Call of Duty - Black Ops, and at rare instances even when using Photoshop.

Here's a snapshot of my system specs - http://speccy.piriform.com/results/LxlbJoOPWFSh0uB5FPGkHwJ

@quietman7 - Thanks a lot, friend. That really does help.

And thanks to everyone else too who has tried to help me, given me advice or even posted in this topic. Thanks a lot guys. :)

Thanks very much for posting back & the clarification of what you meant by running slow, Alvas!

It certainly appears you have more than enough RAM, a decent CPU, and good graphics card to accommodate everything. The reason I had asked was simply based on my own experience when I tried using a few different internet security suite programs and discovered they seriously slowed my computer down when doing just about anything. (I subsequently discovered they are well-known system resource hogs). For that reason, I switched to a free AV program rather than a security suite.

Once I also upgraded the RAM from the original 512 MB to 2 GB, the performance improved quite a lot. Quietman7 has provided a good list of applications. I hope you find the right program for your needs!

Regards,

There are AV programs that allow you to specify programs and folders to be excluded from scanning.

Still even after doing that, most keep scanning other files in the background continuously. It seemed best to get rid of it - and so I did.

Thanks again. :)
