1 Install Unchecky
Unchecky (www.unchecky.com) works silently in the background – if it recognises a dodgy program installer, it’ll quietly make sure any PUP options are unticked or de-selected by default. If you subsequently roll your mouse over any dangerous options, a pop-up Warning window will appear.
2 Buy Malwarebytes
The paid-for Premium version of Malwarebytes also has built-in blocking tools. These will automatically quarantine programs that are deemed as potentially unwanted when they’re detected. If another program is trying to install a PUP, it will be allowed to finish installing if Malwarebytes considers it clean.
3 Fix false positives
If you’re convinced an application is safe – IObit’s Advanced SystemCare, for example – then either ignore Unchecky’s warnings or in the case of Malwarebytes head to the Quarantine section using the menu option on the left and select the allegedly offending item, then click Restore to bring it back.
