A-Squared

A-Squared Free 4 is one of the better free malware removers, but it's not flawless and some users question its efficacy.
The program starts off with a sluggish detection file update that also requires a program restart. This took about 10 minutes. Normally, though, it opens to the Security Status page. From there, you can run scans, update the program, access the A-Squared knowledge base, and choose from among 20 display languages. Program options are arranged on the left nav, and they are Security Status, Scan PC, Quarantine, Logs, and Configuration tabs. Scan PC contains four scanning options: Quick, Smart, Deep, and Custom. Quick Scan is the fastest and most superficial, while the Deep Scan can take several hours.
