What Is Trojan.Downloader.Gen.AC?
Trojan.Downloader.Gen.AC refers to a type of malicious software (malware) that has been classified as a Trojan downloader. This category of malware is designed to download and install additional malicious components or software onto an infected computer. The term "Trojan" originates from the Trojan Horse legend, signifying malware that disguises itself as legitimate software to gain unauthorized access to a computer system. The "Downloader" part of the name indicates its primary function of downloading other malicious files from the internet.
How Trojan.Downloader.Gen.AC Operates
Trojan.Downloader.Gen.AC operates by exploiting vulnerabilities in software or tricking users into executing the malware. Once installed, it can download a variety of malicious software, including viruses, spyware, adware, and ransomware. This malware can communicate with its command and control servers to receive instructions and upload stolen data. It may also attempt to evade detection by security software through various techniques such as code obfuscation or utilizing legitimate system processes to hide its activities.
Symptoms of Infection
Symptoms of a Trojan.Downloader.Gen.AC infection can vary widely depending on the specific payloads it downloads and installs. Common indicators of infection include unexpected changes to system settings, appearance of unwanted software or toolbars, slow system performance, frequent crashes, and unusual network activity. Users may also notice pop-ups, redirects to suspicious websites, or alerts from security software indicating the presence of malware.
- Unexplained changes in browser settings or homepage redirects
- Appearance of unfamiliar programs or icons on the desktop or start menu
- Increased CPU usage or slow system performance without a clear cause
- Frequent system crashes or blue screen of death
How to Remove Trojan.Downloader.Gen.AC
- Enter Safe Mode with Networking: Restart your computer and enter Safe Mode with Networking. This will allow you to use the internet while limiting the malware's ability to interfere with the removal process.
- Conduct a Full Scan: Use a reputable anti-malware tool, such as SpyHunter, to perform a full scan of your system. Ensure the tool is updated with the latest definitions to effectively detect and remove the malware.
- Uninstall Suspicious Programs: Go through the list of installed programs and uninstall any that are unfamiliar or were installed around the time the malware was detected.
- Reset Browsers: Reset your web browsers (Chrome, Firefox, Edge) to their default settings to remove any malicious extensions or settings changes made by the malware.
- Reboot and Re-scan: After completing the above steps, reboot your computer and perform another full scan with your anti-malware tool to ensure all components of the malware have been removed.

Digital Signatures
Digital Signatures
This section lists digital signatures that are attached to samples within this family. When analyzing and verifying digital signatures, it is important to confirm that the signature’s root authority is a well-known and trustworthy entity and that the status of the signature is good. Malware is often signed with non-trustworthy “Self Signed” digital signatures (which can be easily created by a malware author with no verification). Malware may also be signed by legitimate signatures that have an invalid status, and by signatures from questionable root authorities with fake or misleading “Signer” names.| Signer | Root | Status |
