A major issue when dealing with Win.Trojan.Toa-5368540-0 or some other Trojan is that it can be really difficult to spot the infection. Most symptoms associated with this type of malware are situational and really depend on a variety of factors as well as what the virus is actually being used for. There are several typical signs of a Trojan horse attack, which will be listed next, but keep in mind that they might or might not be present in the case of a Trojan horse attack:
- Increased usage of PC resources, most notably CPU time and RAM. If you notice any of this and there is no apparent reason for it, make sure to further investigate the issue since it is highly likely that something’s not quite right.
- Obscure and sketchy online pop-ups, banners and even fake error messages that appear on your browser screen (doesn’t matter if it is Chrome, Firefox or IE)and obstruct your online experience. This is generally a symptom associated with Adware, but it’s possible to occur with Trojans too.
- System instability, sudden freezes and BSOD (Blue Screen of Death) crashes. Those can be caused by all sorts of problems that are not related an infection with malware but if you have recently opened a shady e-mail or downloaded/installed some obscure new program and the crashes started to occur, then it might be a Trojan.
- Other changes to your system. Generally, every time something odd seems to be happening to your PC and you do not know the reason for it, there’s a chance that the changes are due to some unwanted and potentially harmful program.
Dangers of Win.Trojan.Toa-5368540-0

- Theft of personal data. Some Trojans excel at gathering private information about the user of the infected machine. They can use a variety of different espionage methods such as keystroke logging and monitoring of your screen.
