I read that McAfee Site Advisor may be better than the AVG version link scanner.
Is McAfee Site Advisor compatible with AVG Free 9.0.730 if you have disabled Active Search-Shield and Active Surf-Shield?
Search-Shield displays icon with real time safety rating as Surf-Shield prevents you from accidentally becoming infected by drive by downlads and exploits, ensuring the web pages you visit are safe when you are about to click the link.
Downloadable files like screensavers, toolbars and file sharing programs can be-or may be bundled with -- adware, spyware, viruses and other malicious computer code. The siteadvisor team download and install each file they find – they even open zip files. They then scan their test computer to see what changes have been made. If a program is determined to be a virus, Trojan, or certain other types of malware, that program will earn a red rating. So basically all those sites that have a green check mark are reviewed after lot of test process. And if you are using an active mcafee security suite in the computer , its not recommended to use any other security software as they would have conflicts.
