How to fix C:PROGRA~1COMMON~1SystemSysMenu.dll error. The specified module could not be found.



If you are receiving a message about SysMenu.dll, that “the specified module could not be found”, then it seems your PC has been infiltrated by a PUP (potentially unwanted program). A PUP is basically a lite version of a computer virus. There is a 100% chance that some program boarded your PC (we’ll discuss later on how they do it), and that program has an inbuilt capacity to sneakily install other similar files. That’s why you are getting the error message when your PC starts up. Most of the time SysMenu.dll is dubiously either not detected at all by anti-virus programs, or not considered harmful, so you can have a fresh sigh of relief. There’s likely nothing really wrong happening with your system in terms of errors. Rather the files that SysMenu.dll installed are corrupted.


However, we want to give you a big warning here. PUPs generally work slower than most viruses, but if they remain they can progress to the point that they install adware. Adware are the next class in the malware chain. They are not very harmful, but can open doors for much scarier threats if you are not careful. If you feel your PC has slowed down significantly, has issued with freezing and stuttering, or you are experiencing a constant barrage of ads, pop-ups and hyperlinks sponsored by some weird company, you have adware. Adware will try to rig your PC with even more of their kind so refrain from clicking on any warnings about missing plugins, updates for Java, Flash Player, windows or anything else. A big shoutout- adware like to impersonate anti-virus programs that want to scan you – don’t let it.

Remember – adware will try to make you give them access or accept something. If you don’t do that, they are powerless, so simply ignore all messages until you have dealt with SysMenu.dll’s errors and the accompanying files.

But make sure not to take too long. Malware are elaborate. You MAY get tricked. AND if that happens there’s a degree of chance you can end up with a ransomware on your PC. Ransomware are exactly on the opposite side of the food chain from adware. They are the most dangerous, malicious software on the internet. They can really cost you money by encrypting all personal txt, doc, mpp3, avi files (and numerous other extensions) and ask for compensation to decrypt (release) them.

The C:PROGRA~1COMMON~1SystemSysMenu.dll error shows up, as I said, typically when there is a PUP installed. A relevant question you may want to ask is HOW that happened. The answer is – through another program. If you remember downloading and installing some kind of free software -a downlaoder, and optimizer, that sort of thing – look no further. This is the most likely candidate how you got the PUPs and viruses. Next time when you decide to install something carefully watch the steps for things like this:


Alternatively scan the End User License Agreement for any mentions of third-party advertisements.
