Computer Help and Support

If not for you, then for your IT person.

Does your IT person actually manage your computer? (remotely)
The exploit I read relies on remote management.
In any event, I recommend having a virus/malware expert scan the computer.
Did you or the IT person install Webroot anti-virus?
Webroot has been compromised.
Windows defender effectively turns itself off when there is another anti-virus running.

Damage may happen LATER when a start1488 program runs and encrypts files.
You might see a slowdown ( in your process/activity monitor) but that may be advanced for you.

In addition to that link, ask your IT person to watch this video

It is *highly* technical.

But *definitely* have your computer scanned for malware, specificially start1488.exe

If you merely run your own computer "solo" this may not apply.
But it is likely if someone else remotely manages your computer.

HTH

P.S. this is all I know about this. Just pass along to your IT person.
