F-Secure Online Scanner

F-Secure Online Scanner is a small and portable software application that uses Cloud technology to locate and eradicate most types of malware found on your computer.
It requires minimal user intervention, making it ideal for everyone, even people with limited or no experience when it comes to antivirus applications.
Since installation is not a prerequisite, you can drop the executable file to a custom directory on the hard drive and just click it to run.
It is also possible to save F-Secure Online Scanner to a USB flash disk or similar storage unit, in order to run it on any machine effortlessly, without previous installers.
What's more, the app does not add new entries to the Windows registry or create extra files on the HDD.
The interface is represented by a modern window with a clean aspect, where the scanning procedure is automatically initialized. F-Secure Online Scanner proceeds to scan the memory, system and app files. Results show total found threats if any.
The straightforward piece of software doesn't use a high amount of CPU and RAM, so it doesn't affect the overall performance of the PC. It has a good response time and may take a while to complete the scan job, depending on the size of your HDD.
We have not come across any issues throughout our evaluation, since the tool did not hang, crash or pop up error dialogs. Note that F-Secure Online Scanner does not provide real-time protection to your computer against malware, so you still have to install an all-around security application that specializes in this.
