Hi Robert,

We're glad to look into this & help you.
Initially, we'd like to clarify that each antivirus has their own, unique scan engine & algorithm. Hence, the scan result would vary. 
You can be rest assured that your computer would be protected against emerging threats & hackers, with AVG Internet Security installed on it.
AVG program will scan for PUA (potentially unwanted applications) by default. To ensure this : Open AVG Internet Security - Menu - Settings - General - Scans - Below each scan such as Deep scan, you'll be able to find the option. 
If you suspect that your computer is infected, you can try running a boot time scan using AVG. 
If you're still concerned, you can share us the screenshot of the scan results of the other program for better clarity.
