If you've been clicking on paid Google search results, there are chances that your computer has been -- or will be -- attacked by malware bombs.

In a report published by Internetnews.com, security experts say that spammers have been spreading malicious viruses using Google's Adwords as a bait.

The paid search results show up distinctly on top of the page; hence, there is always a chance that a user will click on them. What happens is that a user clicks on an infected link, which looks harmless, and he/she is redirected to a malicious site.

These viruses have been tweaked to escape detection by many antivirus applications; therefore, forget users who have installed free antivirus programs on their systems, even users with a paid antivirus program may wonder what hit his computer and how.

Apparently, if a link on a Google search redirects the user to a site with a malicious code, it violates Google's own policies regarding AdWords, such as not allowing URLs in AdWords results to redirect to other URLs. According to the same report, Google has not commented on the issue.
