Tidserv infections are very common nowadays, and more then just a little annoying. Tidserv malware can be installed on an unsuspecting clients machine with no clear indication that they have even been affected. Fake URLS, peer to peer (P2P) software (like uTorrent), instant messaging links and/or downloads, and even legitimate websites hacked by some ill-willed individual may be one of the ways a computer may become infected.
Internet scamming has become even more profitable then the drug trade. Tidserv is a major contributing factor in this. The process is simple. A malicious coder will disperse the infection in the aforementioned ways. Once he/she has infected computers, he/she will be able to send out even MORE malicious code, or, the “flavor of the week.” They may have complete control of that computer, with the ability to install key-loggers to steal password and bank information. They may also install rogue “anti-virus” software like “XP Security Software 2012.” Cleverly named to mislead people, this fake anti-virus will claim to detect multiple infections on your computer, and you would need to pay for the program in order to remove them. But, of course, when you pay, nothing happens. You just give a crook your hard-earned money and get more malware in the process. Tidserv may also hijack your web browser, and no matter how many times you change it, it always goes back to whatever website tidserv sets the browser to be in.
Even more annoying are the tidserv infections that attack the master boot record (MBR). These infections are on a seperate partition on the hard drive, so even a format wouldnt rid the hard drive of the infection. Upon re-installation of the operating system, the infected MBR would just re-infect the computer. Specialized tools are needed to remove tidserv from the MBR of a hard drive.
Tidserv infections are versatile, and sometimes pretty tricky to fight. They have the ability to phone home for the latest updates to itself, making it just that much harder to get rid of. By infecting a system with its own code, the infection can sometimes remain virtually hidden from even the best anti virus programs out there. Education is the best way to help prevent a computer from being infected, thought nothing is 100%. Keep an eye out for sudden changes in your computers performance, check to see if a new process has started to run during start up, and never click on a “fishy” looking link, and never pay for a program that suddenly has appeared on your computer!
