AVG Antivirus Slowing Down Computer: How to Fix Performance Issues Without Turning Off Protection

If your computer became slow after installing AVG, 👉 1-866-490-0338(USA/UK) ☎️ do not remove protection immediately. The slowdown may be caused by a full scan running in the background, high scan priority, aggressive shield settings, startup load, browser scanning, another antivirus conflict, or a low-resource PC struggling with too many background apps.
AVG provides settings for scan priority, sensitivity, exceptions, and Do Not Disturb Mode. AVG’s scan settings documentation explains that higher scan priority can make scans faster but may slow other processes, while lower priority uses fewer resources. ([AVG Support][5])

.. Quick Answer: How Do I Fix AVG Slowing Down My Computer? ✔ 1➜866((490))➜0338 ⚡
To fix AVG slowing down your computer, restart the PC, check whether AVG is running a scan, lower scheduled scan priority, avoid scanning whole files unless needed, remove conflicting antivirus software, update AVG, add safe exceptions only for trusted apps, and use Do Not Disturb Mode during fullscreen work or gaming.
Do not disable all AVG protection permanently. Optimize the settings first.

.. How to Confirm AVG Is Actually Causing the Slowdown
Before changing settings, confirm AVG is the real reason your computer is slow.
On Windows:
1. Press **Ctrl + Shift + Esc**.
2. Open **Task Manager**.
3. Click **Processes**.
4. Sort by **CPU**, **Memory**, or **Disk**.
5. Look for AVG processes using high resources.
6. Check whether a scan is running.
If AVG usage is high only during a scan, the slowdown may be temporary. If AVG uses high CPU, memory, or disk all the time, you should optimize or repair it.

.. Why AVG Antivirus Can Slow Down a Computer
AVG may slow down your computer when it scans files, checks web traffic, monitors running apps, updates virus definitions, or performs scheduled background tasks.
Common reasons include:
* A full scan is running.
* Scan priority is set too high.
* Scan sensitivity is set too aggressively.
* Whole-file scanning is enabled.
* Another antivirus is installed.
* Your computer has low RAM or slow storage.
* Too many startup apps are running.
* AVG is scanning large folders.
* Browser protection is checking heavy web activity.
* The AVG installation needs repair.
AVG’s documentation says scan sensitivity and scan priority can be adjusted, and higher priority can use more device resources during scans. ([AVG Support][5])

.. AVG Antivirus Slowing Down Computer: 10 Practical Fixes
..# 1. Restart Your Computer First
A restart clears temporary memory, stops stuck processes, and reloads AVG services.
Do this before changing advanced settings:
1. Save your work.
2. Restart the computer.
3. Wait two minutes after login.
4. Open Task Manager.
5. Check whether AVG is still using high resources.
If the slowdown disappears, it may have been a temporary scan or update.

..# 2. Check Whether AVG Is Running a Full Scan
Full scans can use more CPU, disk, and memory because AVG is checking many files.
If a scan is running:
* Let it finish if possible.
* Pause it if you need immediate performance.
* Schedule scans for a time when you are not working.
* Avoid running full scans while gaming, editing video, or using heavy apps.
A full scan is useful, but timing matters.

..# 3. Lower AVG Scan Priority
AVG’s scan settings allow scan priority changes. AVG explains that higher scan priority can make scans faster but may slow other processes, while lower priority reduces the impact on the device. ([AVG Support][5])
To reduce slowdown:
1. Open AVG.
2. Go to scan settings.
3. Find scheduled or custom scan settings.
4. Look for **Scan priority**.
5. Choose **Low** or **Medium**.
6. Save changes.
This may make scans take longer, but your computer should feel more usable.

..# 4. Do Not Use “Test Whole Files” Unless Needed
AVG documentation explains that testing whole files checks the full content of files instead of the parts typically affected by malicious code, and this can take longer for larger files. ([AVG Support][5])
For most everyday users, avoid enabling extra-deep scanning on every scan unless you are troubleshooting a serious infection.
Use deep scanning when:
* You suspect malware.
* You downloaded risky files.
* AVG detected threats earlier.
* You are scanning an external drive.
For daily use, normal scanning is usually more practical.

..# 5. Adjust Sensitivity Carefully
AVG scan and shield sensitivity can affect performance and false positives. AVG’s support documentation explains that higher sensitivity can increase protection but may also increase false positive detections; lower sensitivity may reduce false positives but can reduce effectiveness. ([AVG Support][1])
Use a balanced approach:
* Keep default or medium sensitivity for normal use.
* Avoid high sensitivity on low-end computers unless needed.
* Do not reduce sensitivity too far just for speed.
* Use exceptions for specific trusted items instead of weakening everything.

..# 6. Remove Other Antivirus Programs
Two antivirus programs with real-time protection can compete for the same files and system activity. This can cause slow startup, high CPU usage, scanning conflicts, and protection warnings.
Check for old security apps:
* McAfee trial
* Norton trial
* Avast
* Kaspersky
* Bitdefender
* Malwarebytes Premium real-time protection
* Windows security tools plus another full antivirus suite
Keep one main real-time antivirus active. You can usually keep on-demand tools, but avoid stacking multiple full real-time security suites.

..# 7. Add Exceptions Only for Trusted Apps or Folders
AVG allows exceptions through **Menu > Settings > General > Exceptions**, according to AVG’s FAQ. ([AVG Support][4])
Exceptions can help if AVG repeatedly scans or blocks a trusted work app, game folder, development folder, or backup location.
Use exceptions carefully:
* Add only trusted files or folders.
* Do not exclude your whole drive.
* Do not exclude Downloads.
* Do not exclude unknown apps.
* Remove exceptions you no longer need.
Exceptions can improve performance, but they also reduce scanning coverage for that location.

..# 8. Use Do Not Disturb Mode for Gaming or Fullscreen Apps
AVG’s Do Not Disturb Mode is designed to silence unnecessary notifications while you run apps in fullscreen. AVG says the feature is automatically installed and enabled in AVG AntiVirus for fullscreen app use. ([AVG Support][6])
This may help during:
* Gaming
* Presentations
* Streaming
* Video playback
* Fullscreen work apps
It does not replace performance tuning, but it can reduce interruptions.

..# 9. Update AVG and Windows
Outdated software can cause slow performance, failed scanning, and repeated background activity.
Update:
* AVG program version
* AVG virus definitions
* Windows updates
* Graphics drivers
* Browser updates
After updates, restart the computer and check performance again.

..# 10. Repair or Reinstall AVG
If AVG remains slow after optimization, the installation may be damaged.
Try repair first:
1. Open Windows **Settings**.
2. Go to **Apps**.
3. Find AVG.
4. Choose **Modify**, **Change**, or **Uninstall/Change**.
5. Select **Repair** if available.
6. Restart the computer.
If repair fails, uninstall AVG, restart, and install a fresh copy from the official AVG website.

.. Best AVG Settings for Better Performance
For most users, a balanced AVG setup looks like this:
| Setting | Recommended Choice |
| -- | -- |
| Real-time protection | Keep enabled |
| Scan priority | Low or Medium |
| Scan sensitivity | Default or Medium |
| Full scan timing | Weekly or when PC is idle |
| Whole-file scanning | Use only when needed |
| Exceptions | Only trusted files/folders |
| Other antivirus apps | Remove duplicates |
| Do Not Disturb Mode | Use for fullscreen apps |
This gives better speed without turning off core protection.

.. Should You Turn Off AVG to Speed Up Your PC? ✔ 1➜866((490))➜0338 ⚡
You can temporarily disable some AVG protection for troubleshooting, but you should not leave AVG off permanently. A safer approach is to reduce scan priority, adjust scan timing, remove conflicts, and add narrow exceptions for trusted apps.
AVG’s own support instructions show that shields can be disabled through protection tiles, but this should be treated as a short-term test, not a long-term performance solution. ([AVG Support][3])
