1. Disable the antivirus software

You can also try temporarily disabling your antivirus software. Sometimes your antivirus program can prevent your computer from installing the latest updates.

As a result, simply disabling your antivirus can help you solve this problem. If not, you should completely uninstall your antivirus.

We say completely because when using the usual removal technique, many programs leave behind some leftover files. Over time, that accumulation of files can lead to system slowdowns and other problems.

Therefore, we recommend using specialized software such as IObit Uninstaller to uninstall your antivirus or any other program.

It is extremely easy to use and once you run it you will be amazed at how much free space you get back after surgery.

When you’re done uninstalling the old antivirus and running the operating system updates, don’t leave your PC unprotected, so we recommend switching to a more secure and discreet antivirus like VIPRE Antivirus Plus.

Not only does this security solution not affect your system or the update process, but it is also lightweight on your PC.

VIPRE Antivirus Plus comes with a feature called RapidScan that helps speed up the scanning process. When you start a regular scheduled scan, it skips files that were found safe in previous scans.

This security solution also has cloud-enabled security and threat protection. It also offers protection against ransomware, keeping you safe from such attacks.
