Unplanned Antivirus Adventures: How to Check Your PC for Safety


“Hello, I’m seeking expert advice regarding a potential virus issue. In an attempt to download Optifine for Minecraft, I accidentally initiated a download of unfamiliar antivirus software, including programs named ‘RAV’ and something similar to ‘One Browser.’ I have since removed these programs and cannot locate any remaining files. Currently, I am conducting a full system scan using McAfee. Could you advise me on additional steps to ensure my computer’s security? Are there specific areas I should examine to confirm that my system is uncompromised? Thank you for your assistance; I’m not very tech-savvy.”


In the digital age, accidental downloads are a common concern, particularly when they involve potentially unwanted programs (PUPs) or malware. It’s commendable that you’ve taken the first steps by uninstalling the unfamiliar software and initiating a full system scan with McAfee. Here are additional measures you can take to fortify your computer’s security:

: Ensure that your McAfee antivirus is up-to-date with the latest virus definitions. This allows it to detect and remove the most recent threats.


Perform a Second Opinion Scan

: Sometimes, a secondary scan with a different malware removal tool can catch what your primary antivirus might miss. Consider using reputable software like Malwarebytes for a second opinion.


Check Your Browser Extensions

: Unwanted software often installs additional browser extensions. Check your browser settings and remove any extensions that you do not recognize or remember installing.


Review Installed Programs

: Go to the ‘Programs and Features’ section in your Control Panel (or ‘Apps & Features’ in Windows 10 and later) to review the list of installed programs. Uninstall any that seem suspicious or that you don’t recall installing.


Monitor System Performance

: Keep an eye on your computer’s performance. If you notice unusual behavior such as slow performance, unexpected ads, or random website redirects, it could indicate the presence of malware.


Change Passwords

: If you suspect that your security may have been compromised, it’s a good practice to change your passwords, especially for sensitive accounts like email and online banking.


Backup Your Data

: Regularly back up important files to an external drive or cloud storage. This protects your data in case of a malware attack that requires a system reset.


Educate Yourself

: Familiarize yourself with common cyber threats and stay informed about best practices for online safety.


Consult a Professional

: If you’re still concerned about your computer’s security, consider consulting a professional who can perform a more thorough examination.

By following these steps, you can significantly reduce the risk of malware infection and ensure that your computer remains secure. Remember, staying vigilant and informed is your best defense against cyber threats.
