Why install ASCOMP Cleaning Suite Professional v4.0?

If your computer is beginning to start up more slowly, and your hard drive is becoming increasingly full, a thorough system cleaning can put a spring back in its step.

It's tricky to know what can and cannot be safely removed, and often where to access those files. Cleaning Suite Professional's six system analysers will pinpoint any issues and then aid you in performing a deep clean.

With ASCOMP you can delete temporary files, clean browser histories, caches, and cookies from all popular web browsers, and prevent installed applications and tools from automatically launching at system startup.

Cleaning Suite Professional v4.0 supports Windows 10, 8 and 7.
