CCleaner and Avast AntiVirus install

 Sun City Computer Club members are reporting an install of Avast AntiVirus when loading CCleaner as advised on the club's Windows Malware Removal page.
 As ad blockers become more effective and pervasive, more companies are changing strategy to regain revenue.

 In the case of CCleaner, the unsolicited install of Avast AntiVirus. Avast purchased Piriform (CCleaner's developer) last summer.

 As you may recall CCleaner had problems with distributing malware as part of its install last September.

 More and more sites that distribute applications are offering or loading "companion" applications as well as the intended applications. Read the entire page before downloading. Read the End User License Agreement (EULA) and/or Terms and Conditions before downloading.

 Some users also report difficult or ineffective Avast removal.

 The Global Data Protection Regulation (GPDR) of the European Union has caused some changes in the function of both Avast and CCleaner, causing some to speculate the products were or are collecting user's data.

 CCleaner can be an effective application. This and similar problems/issues are becoming more common. As always be informed, aware, and careful.
