The most significant benefits of anti spyware software is getting rid of any unwanted programs that might have been installed without your knowledge. These programs can redirect internet searches, alter results of a search, or show excessive pop-ups. They may also cause computer slowdowns by taking up processor power, memory and disk space. This could cause performance issues including applications freezing or system crashes. Anti-spyware software is able to identify and fix these issues and make your computer run at a high speed.

Anti-spyware is also a deterrent to criminals from stealing your personal data. Cybercriminals may collect information about your Internet browsing habits, email activities and even download activities. They use this information to hack your accounts, take your money or commit identity theft. These data are often given to third-party companies to use for marketing purposes. If you manage a company malicious hackers are also able to collect information about your employees and clients.

Another disadvantage of spyware is that it may be difficult to get rid of once it has entered the computer. It could, for example, resist attempts to uninstall or shut it down and re-spawn once it is destroyed. In some cases, rebooting the computer that has been infected using safe mode may give an antispyware software program a greater chances of detecting and killing persistent malware. You can also attempt to eliminate the infected software by killing their processes using registry cleaning tools.
