Once run, they will inspect the HDD and OS and detect the malware. At the end, you can use the tools to eliminate the found malware. Security vendors like Eset, Kaspersky and BitDefender offers such online virus scanner tools. They are free and user friendly. You can use such tools when the malware has not affected or hijacked your web browser, though.

Some of the top antivirus tools offer installation in safe mode. They can be handy to remove persistent malware that resists installing the antivirus normally. The new antimalware will offer to remove the compromised software as well during installation. The new antivirus will run in safe mode to find the rogue app and remove it. Some of these tools create a safer pre boot environment and run the detection and cleanup process.

Resorting To Rescue Disk

If you have not created a rescue disc, there are options still. You will find Linux based anti malware rescue discs that can be used to salvage malware invaded systems. Some, such software let you create a bootable USB disk which is easier to use.
