If your PC is connected to just one another computer it makes sense to investigate it as well.
Proposal to create a "security seal" probably comes from some antivirus. Investigate it! Update antivirus definitions.
Remember, having an antivirus with outdated definitions is worse than going without AV at all.
If it's a paid product and your subscription has already expired, deal with it (prolong it, buy another product, install some free antivirus). Before installing another product, uninstall your current AV.
Be careful, now there are many rogue antivirus suites. Their names may sound similar to legitimate AVs.
If these strange addresses appear in history and nobody visits these sites, that's a bad thing. Your PC is probably infected.
If they are in bookmarks, it's not that bad. Many hardware vendors include advertisements into their drivers.
