Major Upgrade to avast! antivirus Released

LONDON and PRAGUE, March 31 /PRNewswire/ --

- ALWIL Software a.s. is Pleased to Announce the Next Major Release of
avast! antivirus, avast! 4.8.

avast! antivirus 4.8 is a major technology upgrade to the avast! product
line, which includes the addition of anti-spyware detection, certified by
West Coast Lab's Checkmark process, and the implementation of anti-rootkit
capabilities, all directly from within avast! antivirus.

Eduard Kucera, ALWIL Software a.s. CEO, said of the release, "While only
an upgrade of avast!, this version represents a major evolution of the avast!
technology. Many of our competitors charge extra for anti-spyware or
anti-rootkit detection, or don't add the functionality at all. We don't think
a partial solution in scanning is a solution at all." Mr. Kucera continues,
"With the release of avast! antivirus 4.8, we have innovated again in the
industry, by adding this functionality to the avast! core scan engine
technology."

avast! antivirus 4.8 is available now for download from the
http://www.avast.com website. The technology is available in avast! Home
Edition (free for non-commercial home use), Professional Edition and avast!
Professional Family pack.

All Editions are available from http://www.avast.com, to purchase online,
or from authorized resellers worldwide.

Existing avast! Home Edition or Professional Edition users will be
prompted to update their programs automatically free of charge.
