Symantec Corp. (Nasdaq: SYMC) today announced the new Mac OS X 10.5 Leopard-compatible version of Norton AntiVirus, featuring new vulnerability protection technology, which delivers protection where many of today's attacks occur - through applications connected to the Internet. Norton AntiVirus 11 for Mac also features a sleeker, redesigned user interface and enhanced performance. Mac users benefit with the number one selling antivirus solution for the Mac, which automatically detects and removes viruses in addition to scanning and cleaning downloaded files and e-mail attachments.

Antivirus programs are completely useless if virus signature files aren't kept up to date. Although keeping files updated is a daunting task on a large network, you can use Symantec System Center to centralize management on your server.

AVG Free Edition provides free antivirus protection for Windows XP/2000/NT/ME/98. Installing only 30Mb of files and 4 running processes, AVG Free Edition is the smallest antivirus scanner we've tested and may well be the best choice for an older PC with severely limited system resources.

GRISOFT is again the recipient of the VB100% Award, as awarded by Virus Bulletin in February 2008. AVG Anti-Virus proved itself by detecting all In the Wild viruses, while generating no false positives, during both on-demand and on-access scanning in Virus Bulletin's comparative tests.

GRISOFT, developer of the AVG family of security software products, today released the second beta edition of AVG 8.O for Windows for public testing. AVG 8.0 offers a completely new multi-threaded scanning engine that combines anti-virus and anti-spyware while retaining the product's signature small footprint and scanning efficiency. Additional protection is provided in the form of safe searching and safe surfing protection acquired through the recent purchase of Exploit Prevention Labs, rootkit detection, basic security for MSN and ICQ instant messaging, and detection of malware-infected files on websites.

As W32.blaster, Sobig, and earlier virus threats have shown, the Internet is not a terribly safe place to connect your PC. Besides updating Windows and your Internet applications regularly, please, I beg you, install two key utilities--a firewall and antivirus software--to ward off future attacks. And if you install any of the products I recommend below, the ounce of prevention won't cost you a dime.
