What happens if anti-virus software finds a virus?

It will immediately block and delete the virus before it does anything bad to your computer.

Antivirus software depends on the virus definitions to identify malware. That is the reason it updates on the new viruses definitions. ... If the antivirus software scans any application or file and if it finds the file infected by a malware that is similar to the malware in the malware definition.

The new line will have the same slope since it is parallel, so it will be y=-x as the start. to find the rest of the equation you use y=-x+b, plug in the numbers you know (-2,-2) and get -2=2+b and solve. Subtract the 2 over and get 0=b and plug that into the final equation. y=-x+0. you don't need the + 0 so it is just y=-x.
