Microsoft on Tuesday released a cumulative security update for Internet Explorer to fix four security vulnerabilities discovered in this popular web browser. Among the holes this patch plugs are two critical flaws already successfully exploited by hackers and used by them to take complete control over affected computers. These flaws also allow planting unsolicited software and dangerous parasites to victim systems. One of the vulnerabilities is used by malicious persons to illegally distribute infamous SpyAxe and WinHound trojans, which push the same named corrupt anti-spyware programs to user PCs. Thousands of malicious web sites secretly install these parasites into each visitor’s system. All it takes to get infected is to visit an insecure site with Internet Explorer running on Windows 98, Me, 2000 or XP (even with Service Pack 2). The victim will not notice anything suspicious, as exploits do not require any user interaction.
However, now the SpyAxe and WinHound infection rate should come to an end or at least noticeably fall off. All the users, even those who do not use Internet Explorer for everyday web surfing, should apply the most recent update. This should not only stop SpyAxe and WinHound, but also reduce the risk of remote intrusion and identity theft.
