Well in my experience AVG Generally sucks balls. I Worked at a PC shop for a while and if you know malware you know that no anti virus can ever entirely protect you.
I find pretty much any Free Anti Virus, preferably Avast, Avira, w/e aren't to bad. HOWEVER for true Protection I HIGHLY recommend the BEST Malware Protection ever. And I'm not just hyping this up. It is seriously one of the best Malware Protection's around. And Honestly I've yet to see any thing come close to comparing to its awesome power.
MalwareBytes
It's not really an Anti Virus But scans for Malware Better then (not going to lie) pretty much any Anti Virus.
Also if you pay for Anti Virus software you're an idiot sorry. Norton sucks.
NOW I am a Malwarebytes Affiliate BUT ONLY because I love there product I wouldn't Affiliate with something I didn't believe in.
So if you'd like to buy the PAID Version of Malwarebytes:
https://store.malwarebytes.org/342/?affiliate=2169&cart=29945&scope=cartAlso the free version will Scan and FIND ALL MALWARE but the paid version just gives you active protection and IP blocking.
Heres my write Up:

CNET Editor's review of Malwarebytes Anti-Malware :
Malwarebytes Anti-Malware is a surprisingly effective freeware antimalware tool. It's a relatively speedy malware remover, with the quick scan taking about 8 minutes even with other high-resource programs running. The heuristics engine proved on multiple computers during empirical testing that it was capable of determining the difference between false positives and dangerous apps.
The app has some nice features rolled in, too. It supports multiple drive scanning including networked drives, context menu options including a scan-on-demand for individual files, and the FileAssassin option under the More Tools section for removing locked files. The interface is simple, but pleasant-looking and well-organized. Tabs live just below the oversized logo, with few options per tab to keep down the clutter. The installation process was fast enough, but interestingly offered up the well-kept changelog and an instant definition file update.
Do note that the real-time protection is restricted to the paid version, as is the scheduler for updates and scans. Overall, though, Malwarebytes Anti-Malware is a responsive malware remover that does what it should with a minimum of fuss
Hope that settles the Anti Virus war for you
