Everyone has most likely used one at some point when they noticed their computer or internet was starting to get slower or they thought they might of picked up a bug.
So why not share with the rest of us what you use so we can all give them a try.
The 2 different tools I use for removing boogeymen and viruses are:
AdwCleaner https://toolslib.net/downloads/viewdownload/1-adwcleaner/
The AdwCleaner utility will scan your computer and web browser for malicious files, browser extensions and registry keys, that may have been installed on your computer without your knowledge.
Malwarebytes Anti-Malware https://www.malwarebytes.org/antimalware/
Malwarebytes Anti-Malware uses industry-leading technology to detect and remove all traces of malware, including worms, Trojans, rootkits, rogues, dialers, spyware, and more.
For cleaning the computer I use:
CCleaner https://www.piriform.com/ccleaner
CCleaner is easy to use, one click cleaning to optimize your computers in seconds by clearing old files, cleaning the registry & it lets you disable unneeded programs at startup.
