When a Proxy Server receives some requests in the non-standard ports or if port-scanning or similar activities are detected, the originating IP is blocked for eight hours. This may happen due to virus or adware infected PCs.

  • If you are using Windows OS, always keep your anti-virus signatures current. You can download the files from CC Current News section.
  • Also, install & update Ad-Aware SE Personal Edition for scanning and cleaning spy-wares, ad-wares etc.
  • Various critical service packs for Windows software can be downloaded from IITG Software Repository.
