Antivirusterra.com is – or was – a very dangerous malicious website. Regardless of whether or not Antivirusterra.com is active, you should not visit Antivirusterra.com for any reason, because the site has a well-documented history of drive-by downloads.
It appears to be the case that sometime very recently, Antivirusterra.com went offline. The website's registration is inactive. However, records indicate that Antivirusterra.com received almost one million hits in the past month, which was a sharp increase in traffic compared to the previous one or two months that the site had been online. Given that all of the major Internet service providers and web browsers have blacklisted Antivirusterra.com and blocked access to it, and the fact that all of the major security software companies have analyzed the site and deemed Antivirusterra.com malicious, it makes sense that Antivirusterra.com would no longer be worth maintaining for the crooks who created Antivirusterra.com.
What Made Antivirusterra.com Dangerous
Unfortunately, drive-by download malware sites like Antivirusterra.com are becoming increasingly common, but they're useless if no one visits them. Antivirusterra.com may have been supported by a browser hijacker, which would have infected the victim computer without the user's knowledge, and then caused the web browser to go to Antivirusterra.com on its own. Alternatively, malicious sites like Antivirusterra.com will show up in search engine results when the sites are new, and so anyone looking for anti-virus software may have visited Antivirusterra.com hoping to find anti-virus software, or perhaps a free virus scan. There is also an existing personal blog called Antivirusterra, which deals with security news, and it is likely that when Antivirusterra.com was new, it drew in people who were looked for the blog.
