TechRepublic has always been a good resource for computers and networking. I was going to quote their 10 dumb things users do that mess up their computers article, but when I clicked on their 10 things category I found something even more useful:
10 things IT pros should do when a relationship ends
#1: Change your passwords at work, if possible
You may feel confident that you never disclosed a password to your Former Significant Other (FOSO, for now). However, being mistaken in your trust can damage your career and possibly cost you your job.
#2: Repair any security breaches you have created
If you have any reason to think that an angry FOSO could gain access to other people’s data, you need to take immediate action.
#3: Change privileges on appropriate programs and systems
If your ex has administrator status on your system, remote access, etc., consider whether that status is still appropriate.
#4: Change passwords on your personal accounts
Okay, okay, it’s obvious. However, simple precautions are all too easy to forget when it’s your own personal heart that’s breaking. Think of all your password-protected places and change them. If you have an online business, be sure to secure access to that account immediately.
#5: Be careful about your communications on company computers
The office is not a prudent place to expose your innermost feelings, especially in writing. Keep in mind that your employer probably has access to all files on an office computer.
#6: Resist the temptation to harm your ex’s system or data
Erasing a critical file, formatting a hard drive, or introducing a clever virus may seem like a satisfying action when you are burning with rage and jealousy. However, all of these are bad ideas.
#7: Resolve any business issues between the two of you
If you and your FOSO worked together, especially if you have an IT consulting firm, the two of you need to straighten out any business matters, including any corporate or partnership matters.
#8: Retrieve your personal information
If your ex has any of your personal files on his or her computer, try to get permission to retrieve or delete them. At the least, ask your FOSO to erase the data.
#9: Refrain from online nastiness
Online communications can last far longer than the rage that spawned them. Venting your most intimate emotions in writing can be a bad idea, especially on the Web.
#10: Resolve any financial issues between the two of you
Longtime couples usually have some financial entanglement. You may need to split everyday stuff, like furniture, DVDs, and china. You should divide and close any joint accounts.
#11: Make appropriate changes to protect your assets
Finally, take appropriate action to protect your own assets. Change the locks on your doors. Change the PIN on your debit and credit cards. Don’t forget to cancel any joint credit cards or lines of credit, unless you and your ex have worked out a different solution.
Taking care of all these details will leave you little time to mope. When it’s all done, you can settle back with the bonbons, the Scotch, or the late night movie. Better luck next time.
