Why do not we support older operating systems with AVG 8.5?
Unfortunately the new scanning engine and on-access scanner, as well as the whole AVG technology cannot work on the old systems. These systems do not provide features and functionality that are necessary for proper detection and especially removal of malware. The systems are insecure and have not been maintained by the OS vendor for several years already. Therefore we cannot guarantee sufficient protection.
Solution
We suggest that you upgrade your OS and/or install the latest Service Pack to be able to use all the AVG features. We also recommend that you use WindowsUpdate to keep your operating system up-to-date.
