A-squared is a venerable free antivirus that includes antispyware and antivirus protection. According to user and industry reviews, the antivirus is particularly good at detecting Trojans. In our own tests, we found this consensus to be true and more than exceeded our expectations. While the program does not include a resident shield, it still can be used in conjunction with other antivirus software to provide dual protection. We will now take a more in-depth look at all of the program’s functionality.
Installation:
The installation of A-squared was very quick. There was no added toolbar or advertising software, unlike 90% of other free antivirus software. There were also few configuration options like adding the scanner to the start menu, taks bar, and a desktop shortcut. After the installation was complete, A-squared started immediately and did not require a restart. A-squared then prompted for an automatic virus definition update. The update was large at 7 megabytes but installed over 35,000 Trojan signatures (this was the first indication that a-squared is clearly geared towards anti-Trojan protection). The update downloaded at about 100 Kilobytes per second and did not appear to have speed limitations like Free AVG. After the update was complete, a-squared simply needed a program restart and the protection was ready to go. The installer also included many different languages including Arabic, English, Japanese, Russian, Dutch and many more.
