It installs with canon presto page manager ( printer application ).
This program is part of Presto PageManager that is bundled with Canon Scanners. This is a valid program but it is not required to run on startup

Identify and removed by AVG as privacy threat

Probable that came in Lexmark/Presto bundle of scanner/printer networking

Saw it in Startup when I ran msconfig.exe. Googled it and found nothing that warrants fear of it being a malicious app. I just installed the software for a new Epson all-in-one, too, so the comments about it being related to printer software seem valid.

Best practices for resolving WrtMon issues

A clean and tidy computer is the key requirement for avoiding problems with WrtMon. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
