I use a FREE software scanning program called: CCleaner.com It takes approx. 30 seconds to SCAN my computer....removes about 15 different types of clutter....including cookies, etc...that tend to interfere with the WGT meter.
Also, I have a FREE version of Advanced System Care6. You can BUY an upgraded version, but, don't think it's necessary. I scan my computer with this system 2 to 5 times a week. It removes privacy errors, any malware, does a complete defrag....just really goes through my entire system and CLEANS it. This SCAN takes approx. 10 minutes to run. Speeds up my PC, yes, I still use a PC.....*smile*. But, I never have WGT meter issues due to the help of these (2) FREE programs.
