How to protect the computer from Trojan:Win32/Wacatac.C!ml?

The initial defense that comes to mind for any computer user is to install an anti-virus or anti-malware program. This move is sensible and probably the most practical way to protect the computer against a Trojan:Win32/Wacatac.C!ml attack. Hence, keep in mind that having security software does not guarantee full protection. The majority of the prevention still lies in being cautious of users, and therefore, we are providing the following information as guidelines to protect the computer from virus infection.

Avoid Malicious Websites

There are enormous numbers of websites that were made for the primary purpose of spreading Trojan:Win32/Wacatac.C!ml. Normally, these sites are involved in integrating malicious pop-up and browser hijacker, that will eventually cause further virus infections. Avoid such websites.

Ignore and Delete Phishing Emails

The mass-mailing of computer viruses gives the attackers the luxury of spreading their malicious code in just one send-off. This will arrive in the inbox as an email that appears to be from a legitimate organization. So, if you receive an unexpected email with a link or an attached file, better delete it immediately.

Do Not Click a Suspicious Link

Links from social media, forums, and blog sites are sometimes being utilized by attackers to drive web users to a malicious page that contains malicious code. Therefore, do not just click on any link, especially if it looks suspicious. Accidental access to the destination site may lead to a Trojan:Win32/Wacatac.C!ml infection.

Be Careful When Downloading Files

Cracked software, serial key generators, and several freeware are seen as another method that spreads the Trojan:Win32/Wacatac.C!ml virus. Avoid acquiring these types of applications, and if there is a need to download freeware or shareware, be sure to obtain it from the official website or trusted providers.

  1. Thank you but I did not need to download the antivirus app that you recommended. I opened the windows defender, ran the full scan and removed the threat and then restart the laptop of windows 10 on which I detected the virus. please I would recommend this way of detecting the virus for windows 8 and 10 users as it is the best way of detecting the virus

  2. Andreas Binder

    Thank you for this information. My laptop got infected via a spam email with a .doc attachment which scanned as harmless but caused the virus to install as soon when opened. I used Malwarebytes and Windows Defender. As long as there was a connection to the web the virus re-appeared and multiplied. Ultimately a system restore to a date before the infection helped.
