Virus and malware removal: what to know

What the job involves, what changes the price, and what to ask a pro.

What virus and malware removal is

A technician scans and cleans a computer of viruses, spyware and unwanted programs, repairs the settings they changed, and advises on protection against reinfection. You need it when the computer shows pop ups, runs slowly, or changes settings you did not change.

Signs you need it

  • Pop ups or ads appear even when you are not browsing
  • The browser homepage or search engine changed without your action
  • The computer runs very slowly or uses high processor or network use for no clear reason
  • Programs you did not install appear on the computer
  • A warning message asks you to pay or call a number to fix the computer

What the pro does

  • Backs up your files before the cleanup, if the drive can be read safely
  • Scans the computer with trusted tools and checks the startup items and programs
  • Removes the infected files, programs and browser extensions
  • Repairs the settings that the malware changed, such as the browser and the network
  • Installs or checks protection and advises on safe habits to avoid reinfection

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • How deep the infection goes and how many programs are affected
  • Whether the computer needs a full reinstall of the operating system
  • Whether the browser, email or accounts need repair
  • Whether files must be backed up before the cleanup
  • Whether the computer is a desktop or a laptop and how many devices are included
  • Whether protection software is set up as part of the job

What a written quote should spell out

  • The scan results and the infections removed
  • Whether a reinstall of the operating system is needed, and why
  • Any protection software installed and its terms
  • Labor for each step, including browser and account repair
  • What to do if the infection returns

Questions to ask before you hire

  • Will you back up my files before you remove anything?
  • Do I need a full reinstall, or can the infection be cleaned?
  • Will you change my passwords or tell me which accounts to change?
  • What protection will you set up, and does it cost extra?
  • What should I do to stop this happening again?
  • Do you check for signs of a hacked account or stolen data?

Red flags

  • Calls you or a pop up unexpectedly and asks for remote access and payment
  • Wants to install software you did not ask for
  • Says the computer is infected without showing the scan results
  • Will not explain the cleanup steps or the results

What you can do yourself

Disconnect the computer from the internet if you suspect an active infection, and do not click on pop ups or call numbers shown on them. Run the built in security tools, keep the system updated, and change your important passwords from a clean device. Call a technician if the computer still misbehaves or you see signs of stolen data.

Licenses and permits

A license is usually not required for virus and malware removal. Check with your state or local licensing agency about any business registration that applies, and ask the technician to show its training or its protection practices.

Virus and malware removal questions

Do I need to reinstall the computer?

Sometimes. A reinstall is the safest option when the infection is deep. A technician will tell you whether a cleanup is enough.

Is a free antivirus program enough?

It can help for basic protection. Ask the technician what it recommends for your use, and avoid programs that you did not check first.

Should I pay a number on a pop up?

No. A pop up that demands payment or a phone call is a common scam, not a real repair service. Close the window, do not call the number, and contact a technician you have checked.
