Here’s a few recent jobs that I can remember off the top of my head:
Remote Virus, Malware, and unwanted programs removal. This image shows a browser search hijack, where instead of opening a Google.com search page it opens a different search page. This was done without the client’s knowledge, probably as a result of downloading free software from somewhere.
Memory upgrade (more RAM).
Remote to fix a Java update that wouldn’t install properly.
New PC setup, including security, and data transfer.
