That's not a malware caused behavior. I've seen similar in Windows when installing/ starting/ running programs.
But if you haven't scanned the computer in a long time for adware and malware....then give the programs below a try and clean the computer, too.
If you want my opinion of what if anything those scans find....then post the logs.
Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the
Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of toolbars....especially Google.
After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.
CCleaner - PC Optimization and Cleaning - Free Download
- download Malwarebytes to your desktop.
- Double-click mb3-setup-1878.1878-126.96.36.1992.exe and follow the prompts to install the program.
- Then click Finish.
- Once the program has fully updated, select Scan Now on the Dashboard. Or select the Threat Scan from the Scan menu.
- If another update of the definitions is available, it will be implemented before the rest of the scanning procedure.
- When the scan is complete, make sure that all Threats are selected, and click Remove Selected.
- Restart your computer when prompted to do so.
