Is PUABundler:Win32/Startfenster dangerous?
I have actually detailed that PUABundler:Win32/Startfenster PUA is not as safe as it claims to be. The “legit and helpful” tool can suddenly unveil itself as a downloader trojan, spyware, backdoor, or coin miner virus. And you can never figure out what to look for even from separate variants of Startfenster unwanted program. That still does not imply that you need to panic – possibly, this nasty thing has not succeeded to do bad things to your computer.
The exact damage to your system can be created not only as a result of the malware injection. A considerable share of doubtful programs, like the Startfenster application is, is just poorly designed. Potentially, their actions are fairly effective than useless if done on specific system setups, but not on each one. That’s how a basic system optimization tool may trigger chaos with constant BSODs on your system. Any interruptions to the system registry are not very safe, and they are a lot more unsafe if performed with such programs.
How did I get this virus?
It is not easy to line the origins of malware on your computer. Nowadays, things are mixed, and spreading tactics utilized by adware 5 years ago may be utilized by spyware these days. However, if we abstract from the exact distribution tactic and will think of why it works, the explanation will be really simple – low level of cybersecurity awareness. Individuals click on advertisements on weird sites, click the pop-ups they receive in their browsers, call the “Microsoft tech support” believing that the scary banner that says about malware is true. It is very important to know what is legitimate – to avoid misunderstandings when trying to determine a virus.
Nowadays, there are two of the most common tactics of malware spreading – bait e-mails and also injection into a hacked program. While the first one is not so easy to avoid – you should know a lot to understand a fake – the second one is very easy to solve: just don’t utilize hacked programs. Torrent-trackers and various other sources of “free” applications (which are, in fact, paid, but with a disabled license checking) are just a giveaway place of malware. And PUABundler:Win32/Startfenster is just amongst them.
