avgnsx.exe closes, Firefox crashes, Google searches redirect

Hi,

Internet searches result in Google redirects. Have AVG 8.5.285 and while on internet frequently get message that avgnsx.exe has encountered a problem and needs to close. More frequently get message that Firefox has crashed and needs to shut down. Have done Ad-Aware scans, cccleaner, and these have not come up with anything also did the Microsoft Windows Malware Removal tool and that did not detect anything. Any help would be much appreciated.
