Con Tries too hard to sell you the paid version
Con Too noisy
Avast! has sounds turned on by default. It also has a lot of blinky features of questionable use.
Con Makes your system slower than usual
Even though scans are not being run in background, it will slow your system.
Con Opt-out installation of Google Chrome
These advertising tactics are simply unacceptable
Con Detection rate isn't too solid
Avast! is not the sort of antivirus product to give you peace of mind. In practice, it does miss some malware every now and then. You'll need backup virus protection, which raises the question why you should get Avast in the first place.
Con Expires after a year leaving computer exposed to new viruses
Expires and stops updating after a year after which the user's computer may become infected by new viruses not covered by existing patterns.
Con "Smart Screen" feature
When running an unknown application, avast will run it wrapped in a sandbox environment first for scanning, then kill the process and re-run it again. A lot of applications do not like this.
Con Moderate effect on performance
Kaspersky is not the most lightweight application or as well optimized as applications such as Lookout. Some slowdowns may be experienced using Kaspersky but that may be a necessary sacrifice for Kaspersky's stronger virus detection rate.
Con Awkward and outdated user interface
Navigating the settings menu and other features in Kaspersky's mobile application is an awkward experience even with new redesigns. The application lacks a consistent design and the settings menu especially feels like one of the earlier Android applications designed.
Con Some basic antivirus features available only for paid users
The free version of Kaspersky will not automatically scan new applications after they are downloaded. Cloud enabled protection to react to fast and new threats is also a paid only feature. The paid version of Kaspersky is $14.95 a year.
