Upd.exe is a very dangerous Trojan horse file that must be removed immediately. Oftentimes it is distributed to your machine by way of viral downloads such as screen savers or smiley emoticons.
This file is not easy to spot once it is downloaded to your computer. It often runs under a variety of file names, masking itself very well. If at all you should take preventative steps towards the attack of these malicious “bugs.” However, you can also remove Upd.exe files them once they are present, at least most of the time.
1. Install registry cleaners. Ideally, this should be done right when you first purchase your computer. Otherwise, it can be hard to remove infections without already causing damage to your hard drive. Popular registry cleaner brands include Eusing, Ccleaner or Comodo.
2. Install anti-virus and anti-spy ware programs. Some of the most reliable brands of such include Norton, AVG, and SpyBot. These different software also play some role in registry cleaning. SpyBot seems to be especially good for this.
3. Be careful what anti-virus or anti-spy ware software you use. You should never download an anti-virus or anti-spy ware/malware program of which you do not know the name. Otherwise, all you can do is make your computer even more vulnerable to vicious threats. Fake virus scanners are especially becoming very popular so watch out!
4. Run your registry cleaners and anti-malware programs regularly. Once a day is ideal. You may want to consider having these programs run in the background automatically during times you do not use your computer often.
5. Update your computer protection and cleaning software often. Every time you update your anti-virus or anti-malware software you are provided with more and more protection. The most reputable software brands (i.e. Norton, Ad Aware, and others) usually offer daily updates.
6. Watch what websites you go to in the future. Many times malicious Upd.exe attacks come from from lesser-known, uncertified or unverified sources. This may not always be true but still you have to be choosy what sites you visit. Also remember that just because a website is on the first page of search engine results does not mean it is the best. Many spammers and unscrupulous marketers use malicious means of getting to the top of search engines in order to scam people.
7. Download only trusty computer software. Not only do you need to make sure whatever software you download is spy ware and anti-virus free, but you also need to trust the software. If the maker has a good reputation (even if it is a lesser-known brand that reaches a specific niche) that would be a great software to use.
Never download software that comes from a source and/or is made in a way that makes you say to yourself, “something is just not right.” Trust your instincts when it comes to using certain kinds of software and say no to any suspicious offers, especially sent to you via e-mail.
8. Stop opening unwanted e-mail attachments. This will help spread of viruses and malware (i.e. Upd.exe) to your computer. Never open any attachments unless they come from a source you trust and if you are expecting to receive it.
