Speccy works best for viewing as an image grab, and I think some people get a website link to their info. I've never used Speccy so I'm not too familiar with it.
MyPCBackup is one of many malware apps that can be accidentally downloaded along with other 'legit' apps. Webcake is another one.
Download and run Revo Uninstaller- the Free version. Remove MyPCBackup and Webcake.
If you can, get me a list of all the installed apps on your system.
Next, download and run AdwCleaner. It will preselect everything it finds, rarely do I have to uncheck anything. It's available in the Downloads section of this site.
Next download and run Malwarebytes. When installing, be sure to UNCHECK the "Trial version of Malwarebytes PRO". Let it update and run a quick scan. You will need to check the scan results carefully- Trojans and Rootkits are automatically selected, but PUPs (Potentially Unwanted Programs-Malware/spyware) WON'T be preselected. I generally always select everything it finds for removal.
Finally run a full scan (if you haven't already) with Avast. Then run AdwCleaner again. You should get a clean bill of health.
