Google: Your computer appears to be infected

Also Known As: Google Malware Notification
Damage level: Moderate

What is Google: Your computer appears to be infected?

If you receive the Google message "Your computer appears to be infected" above your Google search results, your computer is infected with malware, sending fake search traffic to Google using proxy servers. Remove this malware as soon as possible.

If  you receive this message when trying to search for something on Google, your computer is infected by a specific type of malware that uses a number of proxy servers to send fake traffic to Google's search engine. It is unsafe for your computer to remain infected with this malware, since it is not only capable of sending fake traffic to Google, but can also steal your personal data, delete files on your computer, or slow the browsing experience significantly.

Google describes this problem on the official Google blog

Although you should not notice this malware generally on your computer, you will see the Google message appear above your search results, reporting that your computer appears to be infected:

Remove malware, intercepting or redirecting your connection to Google manually

This malware, intercepts your connection to Google and modifies your computer's Hosts file, adding lines to continually redirect the google.com domain to a malicious dedicated server. Follow these steps to fix your Hosts file and remove the malware that is intercepting your connection to Google.

Step 1
The Hosts file is used to resolve some canonical names of websites to IP addresses. When it is changed, the user may be redirected to a malicious site, despite observing a legitimate URL in address bar.

When the Hosts file is modified, it is very difficult to determine if the site if legitimate. To fix this, please download the Microsoft FixIt tool, that restores your Hosts file to the Windows default.

Run this tool when downloaded and follow the on-screen instructions. The download link is as follows:

Step 2
Some variants of this spyware modify system proxy settings so that you cannot access the Internet, or website addresses are redirected to malicious or phishing websites. To reset the proxy settings to the default, download and run this tool:

Step 3
Restart your computer and the Google message reporting that your computer appears to be infected should be gone. If this is not the case, then please describe your problem within our FORUM and our technicians will try to help you.

It is recommended, however, that you scan your computer for malware, since after taking these steps, malicious processes able to change your Hosts file and proxy settings may remain running in the background. We recommend to scan your system with Antivirus software.

Alternatively, you can try other tools to scan your computer for malware, and programs intercepting your connection to Google:
