Virus & Malware Removal

Is your computer running slow? Giving strange errors? Won't do Windows updates properly? Is your web browser homepage getting hijacked? Is your antivirus program giving you fits? If you have any of these symptoms then your computer may be infected with some type of malware or virus.

A majority of computer users don't regularly scan for viruses and malware. What's even worse is the fact that there is no single scanner to remove everything. Many times commercial scanners will find an item only to not be able to delete or clean it. The ability of commercial scanners to find items varies widely as well. Only about 30% of computer users scan for malware regularly and of those over 90% use only one utility.

At Union Square Computers we have a revolutionary approach to virus removal. We start by booting your computer with a specialized version of Windows that we have developed in-house. This version of Windows is clean and uncorrupted by viruses or other malware. Then we perform a battery of scans and tests on your version of Windows. Since the viruses are not active during this process the malware has no way to hide from scanners and removal utilities. During the tests we use a wide array of commercial and proprietary tools to ensure complete removal of viruses from your system.

Our method of virus removal is much more complete than any scan done within the corrupted operating system. Don't be fooled by other companies who claim they can clean your computer up during an afternoon house call or over the internet. They'll be able to remove the "easy" viruses but often leave behind nastier spyware, adware, Trojans, viruses and even rootkits. Our removal method can take several days depending on how infected the computer is but we guarantee that your computer will be returned to you 100% free of viruses and spyware and with free tools highly regarded by security experts to help you stay infection-free.

Free Antivirus, Free Malware Removal Tools, and Free Optimization Utilities

Disclaimer: We feel that the following tools can be useful for detecting and removing malware from your system. Be aware that some malware replaces system files so when infected files are detected and removed your computer may not be able to boot into Windows or macOS. Also these are links to 3rd party sites so be careful what you click on and install. If you are unsure of what to do be sure to contact us before you potentially render your system inoperable. Be sure you know what you are doing and refer to each program's instructions before proceeding.

A note to Windows 8, 10 & 11 Users: Some of these programs need administrative rights in order to remove malware. Simply right click on the program icon and "Run As Administrator" to do this. You'll need to scan again.

Before you start installing programs....
Microsoft Update

Your first line of defense is to make sure that Windows is up-to-date. Contrary to what some self-styled IT gurus may tell you the risk of getting infected by running an unpatched version of Windows is much higher than the risk of Windows Update messing up your computer.

CCleaner clears out your temporary internet files (where malware typically gets a foothold), MRU (most recently used) list, cookies, old installer logs and even performs non-destructive registry cleaning.


This tool defrags your hard drive much more effectively than the defragmentation tool built into Windows.

Note: you shouldn't and don't need to defrag an SSD.

Mac Essentials
Apple Update

Apple regularly releases patches and updates to macOS to improve performance, add features and to patch emerging security threats. By default Mavericks (macOS 10.9) on up checks for updates automatically but people using older versions of macOS should check Apple Update regularly.

AVG Antivirus for Mac

This is the best virus scanner for macOS and it's totally free. Despite what you may have heard Macs are not impervious to viruses. Scan today and find out what is really running on your computer.


While we believe that AVG is the best antivirus available for the Mac you should always get a second opinion from a different scanner. ClamXav is a comprehensive antivirus tool for macOS that does just that.
