Fixing a computer bug can be difficult for even the most experienced computer users. However, if you catch the virus on time, you can remove it with your installed antivirus or a free online antivirus scanner and shouldn't have to call a computer repair expert. Just be aware of the way your computer works, and if you notice that it performs strangely, starts to freeze, turns off suddenly, or opens a lot of unwanted Internet windows, then you may have a virus and need to run your antivirus program.
Disconnect the Internet from the computer either by unplugging the Ethernet cable from the back of the computer or by turning off the modem.
