Information page for Trojans and virus infections on your computer, smartphone, or tablet.<\/p>\n\n\n\n
For more information, see Viruses and Trojans in the Enterprise<\/a>, and the topic Ransomware<\/a>.<\/em><\/p>\n\n\n\n If you think you have a virus or Trojan, start by updating your anti-virus software and then doing a full scan of your system, network, and the external hard drives. If the anti-virus product cannot be updated, then the probability is high that you already have a virus or Trojan. <\/p>\n\n\n\n In this case, you should fall back on the Botfrei EU-Cleaner<\/a><\/strong>. These special programs serve as a first line of help for the detection of viruses and Trojans and can be used in parallel to anti-virus software. <\/p>\n\n\n\n You can manually upload individual files and websites to websites like Virustotal<\/a>, and have them analyzed by numerous anti-virus software programs. If your anti-virus software does not, despite this, find any malware, but you are still suspicious, then you should regularly repeat the full system scan with the most recent updates.<\/p>\n<\/div><\/div>\n\n\n\n If your anti-virus software reports a find, stay calm and firstly save your data. <\/p>\n\n\n\n After you have had a report of a finding, disconnect your computer from the Internet, from your network, and from external devices. This can prevent the malware from being further distributed to other devices. <\/p>\n\n\n\n You should also avoid re-starting or rebooting the infected device. <\/p>\n\n\n\n Instead, put your computer into standby.<\/p>\n<\/div><\/div>\n\n\n\n If you have diagnosed a Banking Trojan infection, you should use a second device to check whether there have already been any irregularities on your account, and you should also immediately change your password for online banking<\/strong>. <\/p>\n\n\n\n Alternatively, you can call your bank to request that the account be blocked. This is possible around the clock using the German national emergency number for blocking cards and accounts: 116 116<\/strong>. <\/p>\n\n\n\n Further information about accessibility from abroad: Website of the emergency blocking number service<\/a><\/strong>. <\/p>\n\n\n\n Alongside online banking, other payment services like PayPal are the target of criminals; here also, you should check your account and perhaps change your password.<\/p>\n<\/div><\/div>\n\n\n\n After a virus infection, change all of your critical passwords, e.g. for your online banking, email addresses, social networks, and online shops. <\/p>\n\n\n\n Our tips for strong passwords<\/a>.<\/p>\n<\/div><\/div>\n\n\n\n If a virus or Trojan has caused any damage, you should immediately report it to the police. <\/p>\n\n\n\n In this case, do not make any independent attempt to remove the malware. This is the only way it is possible for the police to secure evidence and begin an enquiry. <\/p>\n\n\n\n Use a safe second device to file a police report online<\/a> . <\/p>\n\n\n\n If it is not possible to use a separate device, you should go personally to the nearest police station to make your report. Take the infected device with you to the police station to secure evidence.<\/em><\/p>\n<\/div><\/div>\n\n\n\n After an infection with a virus or Trojan, we recommend you restore a backup, especially if you want to continue using the device for business purposes or online banking. <\/p>\n\n\n\n Unfortunately, it cannot be guaranteed that the anti-virus software will remove 100% of the malware. After a new installation or restoring a backup, you should examine your computer again intensively with anti-virus software<\/a>. This is particularly the case for data that you saved after the infection and now wish to use again on the new system. <\/p>\n\n\n\n Help and support in the removal of malware or the reinstallation after a malware infection can be found in the Botfrei forum<\/a>.<\/p>\n<\/div><\/div>\n\n\n\n Most anti-virus software removes viruses and Trojan automatically, or offers quite detailed instructions for manual removal of malware via links. <\/p>\n\n\n\n If you nonetheless have difficulties in the removal of malware, you can get help and support free of charge from the Botfrei Community in the Botfrei forum<\/a><\/strong>.<\/p>\n<\/div><\/div>\n\n\n\n Botfrei.de:\u00a0EU-Cleaner for first aid<\/a> Information page for Trojans and virus infections on your computer, smartphone, or tablet.
