I've used AVG Free addition for years and have been quite happy.

However, in doing some searching on comparison charts and other tech blogs, there are some others that seem to stand out and are rated very high by these sites. I will be trying them out in the near future myself.

ClamWin

PLEASE NOTE: ClamWin Free Antivirus does not include an on-access real-time scanner. You need to manually scan a file in order to detect a virus or spyware.



ALSO NOTE: ClamWin uses the antivirus scanning engine and signature database provided by the Clam Antivirus project.

*Clam is essentially an antivirus program for use on email servers running the Linux operating system.*

ClamWin is another project unrelated to Clam that ports the Clam scanning engine over to Windows use and it is *heavily dependent upon Clam*. Clam is a fairly small operation as antivirus companies go, but ClamWin is even smaller--with only two part-time developers and volunteers for other tasks.

Symantec Security Response has observed a global mass mailer worm spreading and affecting hundreds of thousands of computers worldwide. This appears to be a new attack – likely originating from a botnet – however, it is similar to the classic old school mass-mailing viruses like Nimda, Melissa and the Anna Kournikova virus from 2001. The new, malicious computer worm spreads using a socially engineered email attack. The threat arrives in the form of a standard email that directs the recipient to click on a link embedded in the email. This link points to a malicious program file that is disguised as a PDF file, hosted on the internet. When the user clicks on this link, their computer downloads and launches the malicious file. Symantec customers are protected from W32.Imsolk.B@mm both today and in the future using updates, as well as the products and services outlined in the tabs below.

How can W32.Imsolk.B@mm worm affect me? The worm does not successfully attack Norton/Symantec products, but it disables many other common AntiVirus products. Once running on the computer, the threat attempts to e-mail a copy of the original e-mail to all e-mail addresses found in the infected user’s e-mail address book. The threat also attempts to spread from computer to computer over the local network (to other machines on your home or office network) by copying itself to open drive shares found on other machines on the network. Once the threat copies itself to another machine, if a user even opens the folder that contains the threat on this new machine, this will launch the threat and cause it to spread further through both e-mail and over shared drives. How can I protect myself? We recommend Norton Internet Security 2011. If you have an active subscription of a Norton security product, you are already protected. To get the latest free update visit the Norton Update Center. If you have an expired Norton product, upgrade your product to Norton Internet Security 2011. If you do not have a Norton product, we recommend buying Norton Internet Security 2011. For more information on the threat and protecting yourself, visit the "Here You Have" Information page.
