I am using windows 7. I have a virus symsrv.dll. I can't delete it
Do not download unverified "fixer" tools from random blogs claiming to repair symsrv.dll . Those downloads often contain secondary malware payloads. Use these industry-standard, verified security scanners instead. 1. Run a Deep Scan with Malwarebytes
Restart the computer. As it boots, repeatedly press the key (on older systems) or use the Shift + Restart method from Windows's sign-in screen to access Advanced Startup Options. Select Safe Mode with Networking . This starts Windows with minimal drivers, making it less likely the malware will load.
Open , go to Settings > Security , and ensure "Scan for rootkits" is toggled ON . Run a full scan and quarantine all results. 3. Manual Registry Cleanup (Advanced)
