Another detection of VirusTotal of a Lamzap.exe postedat FreeFixer.com has resulted in primarily ZBot infections associated with the executable file:

lamzap-exe-detections-sensorstechforum

From what it appears up until this current moment, the Lamzap.exe virus may exist in different variants. Researchers believe it to be primarily associated with the following toolbars and malware:

Since most of the detections displayed Linkury on them, researchers believe that if your computer contains advertisements on which the name of Lamzap Is present, you may also see Linkury associated web pages. What surprised us in this particular case was that Razy’s name often appears on the detection, suggesting that Lamzap.exe may be associated with the Razy Ransomware virus.

Lamzap is also widely believed by malware researchers to obtain different information from the user and the computer of the user. Such information may be account credentials, keystrokes, online browsing history and online searches. Since this virus is primarily focused on displaying advertisements, it may use such information to display ads to you related to what you seek online. The adverts may exist in different forms:

  • Pop-up ads.
  • Banners.
  • Ad-supported search results instead of the original ones.
  • Browser Redirects.

Such advertisements may not be dangerous to your computer, but since potentially harmful software like Lamzap.exe may display a wide range of advertisements leading to third-party websites, the virus may cause a malicious redirect which may infect your computer with malware.

To fully erase this ad-supported computer virus, it is strongly advisable to refer to the removal instructions below. Lamzap.exe has also been reported to cause numerous issues to the user PC like slowness and intrusive pop-ups.
