It's free, and you can use it as often as you like to check the security of your system - you only pay if you want to use Prevx CSI to remove infections.
Prevx CSI complements and works alongside your existing PC security solutions to find active infections which have bypassed your antivirus or other security software. Most anti-virus products will only detect about 50% of the new threats we see every month, therefore we offer free use of Prevx CSI to check no threats have evaded your current defense. Peace of mind, free of charge.




Our database includes details of more than 3.5 million infections and we add protection for more than 500,000 new infections every month. That's more than any other security company.

However, for best performance we would recommend at least the following:
Every single day we see more than 5,000 new unique spyware and malware programs. The majority of these new threats would be undetected by most of the popular security programs, including the ones we all use. That means that thousands of users' PCs are being infected by spyware and malware every day and no warning is given because the threats are all undetected.
That's why we developed Prevx CSI. So you can check your PC for signs of infection as often as you like. Peace of mind, free of charge.
