If you search for antivirus software, AVG Internet Security 25.12.10659 shows up almost everywhere. Many people install it once and keep it for years. Version 25.12.10659 feels like a maintenance release, not a flashy redesign, and that’s usually a good thing.
But how does it behave in everyday use?
This article isn’t about lab scores or ads. It’s about what happens when AVG sits on your PC day after day.
What AVG Internet Security Actually Does
At its core, AVG Internet Security watches your system quietly. It scans downloads, checks websites, and keeps an eye on suspicious behavior.
The paid version adds:
- Web protection with phishing alerts
- Ransomware file protection
- Email scanning
- Firewall controls
On my own home PC, the web alerts trigger more often than the virus scans. Most threats today come from bad links, not random files.
Free vs Paid — Where the Difference Shows
AVG Free handles basic virus protection. It works, and many people never upgrade.
The paid version steps in when:
- You shop or bank online
- You open unknown email attachments
- You want alerts before something runs
That extra layer feels useful for shared computers where not everyone clicks carefully.
Performance in Real Life
Here’s where opinions split.
On a modern laptop, AVG Internet Security runs quietly. Background scans don’t interrupt work much. On older machines, startup time can feel longer, especially right after updates.
I’ve seen this firsthand on a family PC. Scheduling scans for nighttime made a big difference.
Internet Blocking and False Alerts
Some users complain that AVG blocks safe websites. This happens more with smaller blogs or forums that use odd scripts.
The fix is simple:
- Open Web Shield
- Add the site to allowed list
After that, the problem usually disappears.
Windows 11 Experience
AVG Internet Security 25.12.10659 works well on Windows 11. Installation is smooth, and system notifications integrate nicely.
One thing to avoid is stacking multiple security tools. Running AVG alongside another antivirus causes conflicts and false alerts.
When AVG Internet Security Makes Sense
This software fits people who:
- Want clear warnings
- Share a computer with others
- Click links from email or social media
It’s less useful for:
- Advanced users who manage security manually
- Older PCs with limited RAM
- People who dislike frequent alerts
Personal Observation
I keep AVG on a family laptop where safety matters more than speed. On my work machine, I rely on built-in protection because I already control what runs.
That difference matters more than features.
Common Mistakes Users Make
- Leaving default scan times active
- Installing extra browser add-ons they don’t need
- Ignoring update prompts
Fixing these keeps AVG quiet and useful.
1) Does AVG Internet Security slow down Windows PCs?
Short answer: It can on older systems, especially during full scans.
On newer machines, the slowdown is usually short and manageable.
2) Why does AVG Internet Security block safe websites?
Short answer: Web Shield can flag sites with scripts or tracking it doesn’t trust.
Whitelisting fixes this in most cases.
3) Is AVG Internet Security better than Windows Defender?
Short answer: It offers more controls and alerts, but Defender is lighter.
Choice depends on how much control you want.
4) Why is AVG using high CPU sometimes?
Short answer: Background scans or updates are usually the cause.
Scheduling scans helps reduce spikes.
5) Does AVG Internet Security work well on Windows 11?
Short answer: Yes, version 25.12.10659 runs smoothly when fully updated.
