PC Optimizer Pro is a PC optimizer utility developed by Xportsoft Technologies. It is classified as a potentially unwanted program, due to its aggressive scan and registration reminders, and that it is often distributed bundled with other programs in a manner that leads many users to not know how it got on their computer. While not inherently malicious, PC Optimizer Pro adds numerous registry keys, startup entries and while running consumes a relatively high amount of system resources, especially during its scans. The software installs from a .exe file that is around 5.20 MB or 5.453.240 Bytes (depending on the version). As of the publication of these videos, the current version of PC Optimizer Pro was detected as malicious or potentially unwanted by at least 21 AntiViruses.
About Potentially Unwanted Applications
If you have ever installed freeware or shareware, chances are high that your computer can get installed with a bunch of unwanted applications. A Potentially Unwanted Program, also called PUP, in short, is actually software that contains adware, installs toolbars, or has other hidden goals. These kinds of programs are almost always bundled up with free software which you download from the net or are also bundled within the custom installers on many download sites.
PUPs did not really constitute pure “malware” in the strict sense of the term. Just like malicious software, PUPs cause problems when downloaded and installed on your PC, but what makes a PUP different is that you give consent to download it – although the truth is vastly different – the software installation package actually tricks you into accepting the installation. Irrespective of whether it is regarded as malware or not, PUPs are nearly always harmful to the user as they might bring on adware, spyware, keystroke logging, and also other bad crapware features on your computer.
What do PUPs do on your computer, exactly?
Potentially Unwanted Programs come in many forms and varieties, but in most instances, these are adware programs that show annoying pop-up adverts and advertisements on websites you check out. The PUPs also get installed into your computer in the form of web browser add-ons and toolbars. Not only they needlessly take up space on your computer screen, but toolbars may also manipulate search engine results, watch your web browsing activities, decrease your web browser’s efficiency, and decelerate your internet connection to a crawl.
Potentially Unwanted Programs at times act quite similarly to viruses or spyware. Some PUPs include keyloggers, dialers, along with other software to gather your private details that may result in identity theft. These are programs that don’t do anything good for you; in addition to taking over space on your hard drive, they also slow down your computer, often modify settings without your approval, the list of bothersome features goes on.
Ways to avoid PUPs
• Always study the EULA and privacy statement. Don’t agree until you know precisely what you are acknowledging.
• Choose the “custom” install whenever installing a software program. In particular, look closely at those small boxes that have been checked as default, where you may ‘agree’ to receive promotions or install software bundlers.
• Use good antivirus software, like Safebytes Anti-Malware that offers real-time protection against PUPs.
• Avoid adding a freeware program you do not use. Turn off or remove toolbars and web browser extensions you don’t really need.
• Always download software from reliable sources like official sites as opposed to untrustworthy sharing space. Avoid file-hosting sites where/when possible.
What you can do if Malware Prevents You From Downloading Or Installing Antivirus?
Practically all malware is bad, but certain types of malware do much more damage to your computer than others. Certain malware goes to great lengths to stop you from downloading or installing anything on your personal computer, particularly antivirus applications. If you are reading this right now, you have probably recognized that a malware infection is the real cause of your blocked web connectivity. So what to do if you need to install an antivirus program like Safebytes? There are a few steps you can take to circumvent this problem.
Install in Safe Mode
The Windows OS has a special mode known as “Safe Mode” in which just the bare minimum required programs and services are loaded. In the event the malware is blocking the internet connection and affecting the computer, running it in Safe Mode will let you download antivirus and run a diagnostic scan while limiting possible damage. To start the computer into Safe Mode, press the “F8” key on your keyboard right before the Windows boot screen comes up; Or right after normal Windows boot up, run MSConfig, look over “Safe Boot” under Boot tab, and click Apply. After you reboot into Safe Mode with Networking, you can download, install, and update anti-malware software from there. Right after installation, run the malware scanner to remove standard infections.
Switch to an alternate browser
Some malware may target vulnerabilities of a specific browser that block the downloading process. If you seem to have malware attached to Internet Explorer, then switch over to an alternate web browser with built-in safety features, such as Firefox or Chrome, to download your favorite antivirus program – Safebytes.
Install and run anti-virus from the USB drive
Another solution is to create a portable anti-malware program on your USB stick. Adopt these measures to employ a thumb drive to clean your infected computer system.
1) Download Safebytes Anti-Malware or MS Windows Defender Offline onto a clean PC.
2) Plug the Thumb drive into the clean computer.
3) Run the setup program by double-clicking the executable file of the downloaded software, with a .exe file format.
4) Choose the flash drive as the location for saving the file. Do as instructed on the screen to complete the installation process.
5) Now, plug the pen drive into the corrupted computer.
6) Double-click the anti-malware software EXE file on the USB flash drive.
7) Press the “Scan” button to run a full system scan and remove viruses automatically.

Error Causes
The true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP.
Cloudflare VP Dane Knecht was the first to report the underlying BGP problem. This meant, as Kevin Beaumont, former Microsoft's Head of Security Operations Centre, tweeted,
"By not having BGP announcements for your DNS name servers, DNS falls apart = nobody can find you on the internet. Same with WhatsApp btw. Facebook has basically de-platformed themselves from their own platform."
Many people are very annoyed by this and with the fact that they cannot use their social media platforms but it seems that Facebook employees are in even bigger annoyance as it was reported that Facebook employees can't enter their buildings because their "smart" badges and doors were also disabled by this network failure. If true, Facebook's people literally can't enter the building to fix things.
Reddit user u/ramenporn, who claimed to be a Facebook employee working on bringing the social network back from the dead, reported, before he deleted his account and his messages:
"DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC). There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures."
Ramenporn also stated that it wasn't an attack, but a mistaken configuration change made via a web interface.
Both BGP and DNS are down, the "connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally."
Technicians on site don't know how to do that and senior network administrators aren't on site.
It seems that it will all be down for a couple of more hours before the issue is resolved.
