A-fast Antivirus is a rogue program that attempts to convince computer users to be able to protect computer from viruses. Unfortunately, the reality is different and A-fast Antivirus has nothing in common with a legitimate antispyware tool. It is just one more infection that spreads on computers by employing Trojan viruses and later attempts to rip computer users off.

When A-fast Antivirus is infiltrated into the system, it enters Windows Registry and modifies some entries there. After these modifications are done, A-fast Antivirus is able to display tons of pop up ads warning about infections detected. Every such security notification ends with a suggestion to purchase A-fast Antivirus. Here is how these notifications look like:

Critical System Warning!
Your system is probably infected with a version of Trojan-Spy.HTML.Visafraud.a. This may result in website access passwords being stolen from Internet Explorer, Mozilla Firefox, Outlook etc. Click Yes to scan and remove threats (recommended).

Moreover, when the program enters the machine, it loads a scanner after each computer reboot. A-fast Antivirus pretends to look for infections and then displays a list of them stating that they must be immediately removed. Actually, A-fast is not able to detect or remove any real infections so you have to ignore any scan results it provides.

Instead you should consider removing A-fast Antivirus to terminate all these annoying actions and get rid of this infection.
