Computer acting strange? Could be malware.
Unwanted pop-ups, browser hijacks, or a sudden ransom note are all reasons to stop using the machine and get it checked properly.

HP Spectre 13 laptop I had a failing SSD. I came to Dotronix for their expertise. They managed to replace the hard drive and also reinstall Windows 11 as well as change the thermal paste. A very good job done by the team, will definitely come again.

Google Review · Kepong BranchWhat's going on
A single antivirus scan often misses persistence mechanisms — scheduled tasks, startup entries, or browser extensions that silently reinstall the infection after a surface-level clean. We isolate the machine from the network first to stop any spread or data exfiltration, run full-system scans with multiple engines, and specifically hunt for the persistence mechanisms that let malware survive a basic clean-up.
Common signs to look out for
- Excessive pop-ups appearing in the browser or desktop
- Homepage or search engine changed without permission
- Programs opening or closing on their own
- Dramatically slower performance than usual
- Unfamiliar programs appearing in the startup list
What usually causes it
- Bundled software installed alongside free downloads
- Phishing email attachments or malicious links
- Outdated OS or browser with unpatched vulnerabilities
- Cracked or pirated software carrying hidden payloads
How we diagnose this
Network isolation
The machine is disconnected from the network first, to stop any spread or data exfiltration.
Multi-engine full scan
We run comprehensive scans with more than one detection engine, since no single tool catches everything.
Persistence check
We specifically hunt for scheduled tasks, startup entries and browser extensions that let infections survive a basic clean.
Clean & harden
The system is cleaned, updated, and browser settings reset to reduce the chance of reinfection.
