Editors' Review

Kingsoft Antivirus 2012 is a free Internet security program for scanning and defending your computer against malicious files and/or hackers.

A quick scan only takes a couple minutes. For a full scan, which scans all of your drives, it can take from an hour and a half to 2 hours to complete. On average, it scans 93 files per second. You do need to use the full scan every once in a while, though, because it picks up on threats that the quick scan will often miss. We take care not to download anything questionable, but threats are not completely unavoidable. That's why this antivirus software also has Defense and Anti-Hacker functions in order to help prevent or catch security risks online and on your computer. Utilities can also scan and fix system vulnerabilities, which can help with the speed and quality of your computer use. Settings allow you to customize the antivirus software to your needs as well, and add trusted files to be overlooked during scans. Kingsoft also has a feedback page so you can personally help in improving any bugs that might arise while using it.

Kingsoft Antivirus 2012 was easy and simple to download. There wasn't anything an average computer user would have had difficulties with during the download process. We are satisfied with how it works and how easy it was to set up.
