I've found a program called nav.exe; some google searches have told me its a virus, others say its safe. I used to have Norton Antivirus but my subscription expired, I have reason to believe this may be a virus, as it seems that fake updates have been installing, I am unable to upgrade to windows 10 (I run on 8.1), and my PC has slowed down significantly. My disk, according to task manager, has always been at 100%. nav.exe, according to my resource monitor, apparently is writing at almost 2 million bytes per second and reading at 137 bytes per second. What should I do?

Hi JackofAllTrades :)

Where is that nav.exe file located? In which folder? Also, can you upload it on VirusTotal and post the result URL here?

You have to be careful when conducting searches on the Internet as there is a lot of useless and misinformation out there especially in regards to malware removal assistance (and removal guides). It is not unusual to find numerous hits from untrustworthy and scam sites which mis-classify detections or provide misleading information. This is deliberately done more as a scam to entice folks into buying an advertised fix or removal tool. Scammers take advantage of novice users and entice them into downloading junk software using gimmicks, false claims and other deceptive advertising. In some cases if the fix is a free download, users may be enticed to download dubious software, malicious files or even be redirected to a malicious web site. When performing search queries, always check multiple sources to confirm the information provided is safe, consistent and from trustworthy web sites.

Answering the questions asked by Aura will be helpful to him in assisting you as well as uploading the file for analysis.

Can't really track it. Most of it seems to be coming from C:\ProgramData\Norton... not from where the actual Norton Anti-Virus main files are found (Windows C:\Program Files\Norton AntiVirus). Also, nav.exe seems to be behaving erratically... its processes (viewed within the resource monitor) are starting and stopping seemingly at random.

I'm about 87% sure that nav.exe is whats causing my PC to slow down, because when many of its processes end, my disk (as viewed in the task manager) goes back to normal levels (10% - 0%)

nav.exe using a lot of resources and hogging the disk usage is a known issue. If you really have Norton installed, and/or nav.exe is launched from a Symantec folder, it's the real thing, legitimate as well. This being said, I suggest you to uninstall and reinstall your Norton product if you keep having issues with it. Make sure to use the clean-up tool after the uninstall to make sure that there's nothing left behind.
