Default "Best" (i.e. smallest footprint on hd) free antivirus program for netbook?

Title pretty much says it all...

I have a super-small solid-state drive on my netbook, so "size" is the primary consideration driving most of my software decisions.

I get Symantec 12.1 AntiVirus for free through work, but have also used the free versions of Avira and Avast in the past.

The netbook is running WinXP Home, and I'm familiar with chaslang's excellent "How to Protect yourself from malware!" thread... just wanted some opinions on footprint.

Thanks in advance.

Might I suggest Microsoft Security Essentials for all of the above.

Thank you for the recommendation.

I found a CNET Editors' Review of MSE (2.0):
  • Microsoft Security Essentials
    Quote:
    Most of the changes in MSE 2 are under the hood, but it's still a worthwhile program in terms of features, especially on lower-powered Netbooks.

    <snip>

    Conclusion
    Security Essentials is basically a good set-it-and-forget-it security program, but if you want more options and better results from a lightweight security option, Panda Cloud Antivirus Free Edition 1.3 is the safer bet.

This led me to investigate Panda Cloud Antivirus, and I found a CNET Editors' Review of it, as well:
  • Panda Cloud Antivirus Free Edition
    Quote:
    the program attained its goal of freeing up system resources by putting much of the program's heavy lifting in the cloud.

    <snip>

    It has added a full on-demand scan, and it runs at around 15MB of RAM when idle and around 60MB when scanning. It's a great choice for resource-conscious Netbook users.


For Geeks finding this post in a search, here are the relevant MG links:

And the relevant Wikipedia entries:
  • Microsoft Security Essentials
    Quote:
    Hardware requirements for Microsoft Security Essentials differ, depending on the operating system. For Windows XP, Microsoft Security Essentials requires at least a 500 MHz processor and 256 MB of RAM. On Windows Vista and Windows 7, Microsoft Security Essentials requires a 1 GHz processor and 1 GB of RAM.

    <snip>

    PC Magazine cited Microsoft Security Essentials's small installation package (about 7 MB, depending on the operating system) and its speedy installation. On the downside, the full installation occupied about 110 MB of disk space, and the initial update took 5 to 15 minutes.
  • Panda Antivirus (the company)
    Quote:
    This security model presented in 2007 was called “Collective Intelligence” and is the basis of the new solutions that offer security from the cloud.

    This technology is implemented in its 2009 and 2010 antivirus products for home users and in the new Panda Cloud Antivirus, which the company has classified as the first antivirus in history that provides protection from the cloud.

    These antivirus products only include the information about malware samples that cause most infections at any given moment, while the rest of the information is stored in Panda’s knowledge base. The antivirus connects to this knowledge base whenever necessary. This system is designed to offer real-time protection against thousands of new malware samples, use the community knowledge base to offer further protection and not to consume computer resources.
  • Panda Cloud Antivirus (the product)
    Quote:
    It is cloud-based in the sense that files are scanned on a remote server without using processing power of the user's machine. The cloud technology is based on Panda's Collective Intelligence.[1] It can run constantly, providing protection against viruses and malicious websites but slowing the system to some extent[2] as all such software does, or do a system scan.

    <snip>

    Panda Cloud Antivirus relies on its "Collective Intelligence" and the cloud for up-to-date information. It normally uses an Internet connection to access up-to-date information; if the Internet cannot be accessed it will use a local cache of "the most common threats in circulation".

    <snip>

    Tech Radar's review states "We think that Panda Cloud Antivirus is best viewed as a defense tool rather than a utility for cleaning up a system that's already riddled with infection."

    Lifehacker's review states that the antivirus is lightweight, and is a fresh approach to attacking malware. However they did not try to detect real malware (only tracking cookies) in their test.

    When Softpedia reviewed the software they said that it had a high overall detection rate, but had trouble listing all the results. Overall they say it is the best in the market for lightweight usage, and is easy to use, with a clean interface.


Microsoft's page for MSE:
  • Microsoft Security Essentials
    Quote:
    Microsoft Security Essentials is efficient and compact. Scans and updates are scheduled to run when the PC is idle and the software works in a way that your PC is still snappy when you’re using it. All this makes Microsoft Security Essentials friendly for all sorts of computers—your old PC, your new PC, your laptop, as well as your little netbook.

Panda's page for PCA:
PC Mag's review of MSE 2.0:
  • Microsoft Security Essentials 2.0
    Quote:
    Cons
    Protection weaker under Windows XP

    <snip>

    In the Windows XP test, though, Microsoft took just 11.5 points, not enough for certification. It score high for usability but low for protection and repair. Quite a few products scored lower under Windows XP. Norton was the only one to reach 16 points in both tests.

PC Mag's review of PCA 1.5:
CNET article on the release of MSE 4.0:
  • Microsoft Security Essentials 4.0 ready for download/
    Quote:
    As ZDNet sister site TechRepublic reported back in December 2011, Microsoft officials said the 4.0 release would include a streamlined interface; a renamed version of the SpyNet service (now slated to be known as Microsoft Active Protection Services); new automatic remediation functionality; and overall improved performance and detection capabilities.

Have a look at Avast Free v7.0. Some people have issues but if it runs good, it runs great and it has a small memory print.

Thanks! Guess I will look at MSE, PCA, and Avast.

I'll compare the size of the installation package (not really an issue, and can always install from flash drive or SDHC card), as well as size on disk.
