Antivirusan.com

Antivirusan.com is one of many malicious websites that market the fraudulent rogue security program Antivirus Protection. Exposure to Antivirusan.com or application related to Antivirusan.com has been known to infect the PC in question with a web browser hijacker that persistently redirects the browser back to Antivirusan.com. Browser hijacks may also create fake error messages that block access to normal websites or change your homepage without permission. If you're infected with Antivirusan.com's browser hijacker or Antivirus Protection, you should be ready to use the strongest anti-malware program that you can afford to remove these Antivirusan.com-linked threats.

Antivirusan.com is a New Domain Name for a Well-Seasoned Scam

Antivirusan.com is a simple copy of other websites that try to market Antivirus Protection or one of its many clones. Some samples of Antivirusan.com's 'twin' sites include Antivirvip.net, Antivirart.com, Antivirea.com and Antivirat.com. The main danger in these websites lies in your taking their fake marketing claims seriously and purchasing Antivirus Protection.

Antivirus Protection is itself known by other names like Antivirus Monitor and Antivirus Scan. Although these programs pretend to be good anti-virus scanners, they have functions that are not beneficial for your PC. Their primary symptoms are fake errors like the one you can see below:

Security Alert
Virus Alert!
Application can't be started! The file [application file] is damaged. Do you want to activate your anti-virus program now?

A variety of attacks may use these error messages to mislead you into believing that unrelated infections are causing other system problems. Antivirusan.com malware may change your system settings, stop you from accessing other programs, or hijack your web browser and redirect you to Antivirusan.com..

Purchasing an activation key for Antivirus Monitor or any other Antivirusan.com security product may reduce the program attacks, but this also places your credit card in danger of repetitive fraudulent charges. Removing Antivirusan.com threats by using appropriate anti-malware solutions is a more beneficial option in the long term.
