ARCHIVED: On my PC, why am I having network problems after installing file-sharing software?
Peer-to-peer Internet file-sharing programs (e.g., BitTorrent clients such as µTorrent, Gnutella network clients such as Shareaza, and ED2k clients such as eMule) often slow a network connection or cause network problems for various reasons:
- They can use up a lot of bandwidth. If you transfer only a few files, you may not notice any problems, but when you share several files at once, your networking performance may drop sharply.
- Many file-sharing programs are configured to launch in the background every time you log into your computer, so you may share files unknowingly.
- Some peer-to-peer file-sharing programs include third-party software, such as spyware, adware, or malicious programs such as keyloggers and Trojans. These programs take up bandwidth in reporting back to the programmer or another compromised computer, and in some cases set your computer up to be part of a botnet, which causes a slowdown.
- The peer-to-peer networks to which these programs connect may contain malicious software (malware) masquerading as legitimate files. The software's actions (infecting your computer and subsequently propagating themselves) will slow your connection.
If you experience network problems after installing file-sharing programs:
- Disable the file-sharing program from starting automatically. How
you do this depends on the program, but in many cases, if there's not
a setting within the program to reconfigure this, you can do the
following:
- Click , then or , and then .
- Locate the file-sharing program, and then right-click it. Select .
- ARCHIVED: Remove the third-party accompanying programs, and/or ARCHIVED: run security software to remove infections. Keep in mind that this sometimes renders the file-sharing program dysfunctional.
It is impossible for UITS to compile an exhaustive list of potential malware or all the third-party applications that, if not malicious, still affect network performance. The following security packages available from Indiana University detect most problematic third-party programs:
- Symantec AntiVirus
- While Symantec AntiVirus exists primarily for virus,
worm, and Trojan removal, it also detects and quarantines or removes
spyware, adware, and other types of malware.
- Windows Defender
- Windows Defender is Microsoft's antispyware program. It is available as a stand-alone product or as part of Windows 7 or Vista. It can scan for and remove spyware components from your computer's memory, registry, and hard drives.
