avast! 4 is a full-featured antivirus package designed exclusively for home users and non-commercial use. The latest version of avast! antivirus kernel features outstanding detection abilities, together with high performance. You can expect 100% detection of In-the-Wild viruses (viruses already spreading between users) and excellent detection of Trojan horses. The kernel is certified by ICSA; and frequently takes part in the tests of Virus Bulletin magazine, often yielding the VB100 award.

The avast! engine also features outstanding unpacking support. It can scan inside the following archives: ARJ, ZIP, MIME (+ all associated formats), MAPI (Outlook pst files), DBX (Outlook Express archives), RAR, TAR, GZIP, CAB, BZIP2, ZOO, ACE, ARC, LHA/LHX, TNEF (winmail.dat), CPIO, CHM, RPM, ISO, 7ZIP and SIS. It also supports a number of executable packers (such as PKLite, Diet, UPX, ASPack, PeShield, FSG, MEW etc.). Last, but not least, it can also scan for viruses hidden in Alternate data streams on NTFS volumes.

avast! antivirus 4.8 now has anti-spyware, anti-rootkit and strong self-protection, all built in to avast!, offering the best value anti-malware product you can buy.
