If you suspect there is malware on your computer, take these steps:
Stop shopping, banking, and doing other online activities that involve user names, passwords, or other sensitive information.
Update your security software, and then scan your computer for viruses and spyware. Delete anything it identifies as a problem. You may have to restart your computer for the changes to take effect.
Check your browser to see if it has tools to delete malware or reset the browser to its original settings.
If your computer is covered by a warranty that offers free tech support, contact the manufacturer. Before you call, write down the model and serial number of your computer, the name of any software you've installed, and a short description of the problem.
Many companies — including some affiliated with retail stores — offer tech support.Telephone and online help usually are less expensive, but online search results might not be the best way to find help. Tech support scammers pay to boost their ranking in search results so their websites and phone numbers appear above those of legitimate companies. If you want tech support, look for a company’s contact information on their software package or on your receipt.
