will virus transfer to a replacemnt computer

No. Not until you copy something from your old laptop to new one.

Yes  - (It very much depends on what your computer is infected with, and if there are other infected computers/devices on the network, when you plug your new computer into it.  How will you be restoring/transferring data from your old computer?)

"A Virus is a program that is activated by attaching copies of itself to executable objects. Viruses can reach your computer from other infected computers, via data medium (CD, DVD, etc.) or through a network (local or Internet)."

"A computer virus is a type of malware that propagates by inserting a copy of itself into and becoming part of another program. It spreads from one computer to another, leaving infections as it travels."

Don't allowing a computer with a virus;  onto a network or the internet... If you truly have a virus, there is potential for other devices/computers, on the network, to also become infected.

And, with the sync abilities of Mfg Ecosystems (Apple, Microsoft, Google) and Browsers, some maliciousness (infected files, search preferences, etc) may transfer among devices after logging in.(even after a clean install or logging into a newly purchased device).

Please Consider answering PA Bear's Question -> "How have you determined that the computer's infected ... ?"

Thank you very much

If you sync your profile in Chrome or Internet Explorer (mainly Win8/10 synced to a MS account) or Firefox, etc- malicious home pages and/or malicious search preferences, may come back after a Win10 Reset, clean install, or if you purchase a new computer. Review and/or Reset the home pages, and re-examine the search preferences, after signing into the browsers on the new computer.  Remove and re-add desktop and taskbar browser shortcuts.

Some viruses can infect other network devices, as PA Bear asked -> "How have you determined that the computer's infected...?"

How have you determined that the computer's infected, Della?
